Abstract

A display device includes a backlight assembly, a display panel, a top chassis and a sealing member. The backlight assembly includes a light-generating unit, a receiving container receiving the light-generating unit and a mold frame disposed along an edge portion of the receiving container. The display panel is disposed on the mold frame. The top chassis is coupled to the receiving container, covers an edge portion of the display panel and fixes the display panel by. The sealing member is disposed between the mold frame and the top chassis to surround an end portion of the display panel, such as to fully seal a space between the end portion of the display panel and the mold frame. The sealing member has elasticity, insulating properties and adsorption capacity for foreign matter.

Claims

1. A display device comprising:

a backlight assembly comprising a light-generating unit generating light, a receiving container receiving the light-generating unit, and a mold frame disposed along an edge portion of the receiving container;

a display panel disposed on the mold frame to display images by using the light;

a top chassis coupled with the receiving container, covering an edge portion of the display panel and fixing the display panel; and

a sealing member disposed between the mold frame and the top chassis and surrounding an end portion of the display panel, the sealing member fully sealing a space between the end portion of the display panel and the mold frame, and having elasticity, insulating properties and adsorption capacity for foreign matter.

2. The display device of claim 1, wherein the mold frame comprises:

a mold bottom part disposed substantially in parallel with a lower surface of the display panel facing the receiving container, the mold bottom part supporting the display panel; and

a mold side part extended from the mold bottom part and facing the end portion of the display panel.

3. The display device of claim 2, wherein the sealing member fully seals a space between the end portion of the display panel and the mold side part.

4. The display device of claim 3, wherein the sealing member contacts the end portion of the display panel and an edge portion of the lower surface of the display panel.

5. The display device of claim 3, wherein the sealing member contacts the end portion of the display panel and an edge portion of an upper surface of the display panel.

6. The display device of claim 3, wherein the sealing member contacts the end portion of the display panel, an edge portion of a lower surface of the display panel, and an edge portion of an upper surface of the display panel, the end portion of the display panel being directly adjacent to both the edge portion of the lower surface and the edge portion of the upper surface of the display panel.

7. The display device of claim 6, wherein the sealing member is a continuous member.

8. The display device of claim 6, wherein the sealing member comprises:

a lower sealing part contacting the end portion of the display panel and the edge portion of the lower surface of the display panel; and

an upper sealing part contacting the end portion of the display panel and the edge portion of the upper surface of the display panel.

9. The display device of claim 8, wherein the lower sealing part seals a space between the mold bottom part and the lower surface of the display panel, and

the upper sealing part seals a space between the top chassis and the upper surface of the display panel.

10. The display device of claim 1, wherein the sealing member comprises a silicon material.

11. The display device of claim 1, wherein the sealing member comprises a plastic material having high elasticity.

12. The display device of claim 1, further comprising a panel-supporting part disposed on the mold bottom part and contacting a lower surface of the display panel, the panel-supporting part having elasticity to support the display panel.

13. The display device of claim 1, further comprising a panel-pressing part disposed on an inner side surface of the top chassis, the panel-pressing part having elasticity and pressing the display panel.

14. The display device of claim 13, wherein the panel-pressing part comprises a conductive material emitting static electricity of the display panel.

15. A method of manufacturing a display device, the method comprising:

manufacturing a backlight assembly including a light-generating unit generating light, a receiving container receiving the light-generating unit and a mold frame disposed along an edge portion of the receiving container;

forming a sealing member on at least one of the mold frame and a top chassis which will be coupled to the receiving container;

disposing a display panel displaying images on the mold frame; and

coupling the top chassis and the receiving container, such that the sealing member surrounds an end portion of the display panel and fixes the top chassis to the display panel.

16. The method of claim 15, wherein the mold frame comprises:

a mold bottom part disposed substantially in parallel with a lower surface of the display panel facing the receiving container, the mold bottom part supporting the display panel; and

a mold side part extended from the mold bottom part and facing the end portion of the display panel,

the sealing member fully sealing a space between the end portion of the display panel and the mold side part after the top chassis is coupled to the receiving container.

17. The method of claim 16, wherein the forming a sealing member includes disposing the sealing member on the mold bottom part, the sealing member having a protruding shape protruded toward the top chassis and fully sealing a space between the end portion of the display panel and the mold side part.

18. The method of claim 16, wherein the forming a sealing member includes disposing the sealing member on an inner side surface of the top chassis, the sealing member having a protruding shape protruded toward the receiving container and fully sealing a space between the end portion of the display panel and the mold side part.

19. The method of claim 16, wherein the sealing member comprises:

a lower sealing part disposed on the mold bottom part; and

an upper sealing part disposed on an inner side surface of the top chassis to correspond with the lower sealing part.

20. A method of manufacturing a display device, the method comprising:

manufacturing a backlight assembly including a light-generating unit generating light, a receiving container receiving the light-generating unit and a mold frame disposed along an edge portion of the receiving container;

disposing a display panel displaying images on the mold frame;

forming a sealing member on the mold frame and surrounding an end portion of the display panel; and

coupling a top chassis and the receiving container to fix the display panel.

21. The display device of claim 20, wherein the mold frame comprises:

a mold bottom part disposed in parallel with a lower surface of the display panel facing the receiving container to support the display panel; and

a mold side part extended from the mold bottom part and facing the end portion of the display panel,

the sealing member fully sealing a space between the end portion of the display panel and the mold side part after the top chassis is coupled to the receiving container.
