Abstract

A display device includes a display panel, a touch screen panel and a receiving container. The display panel displays an image. The touch screen panel is spaced apart from the display panel. The receiving container receives the display panel and has a venting part facing a side surface of the display panel to reduce a pressure difference between a pressure in a space between the display panel and the touch screen panel of the display device and a pressure exterior to the display device.

Claims

1. A display device comprising:

a display panel which displays an image;

a touch screen panel disposed above the display panel; and

a receiving container including a mold frame which has an upper surface facing a lower surface of the touch screen panel, and receives and supports the display panel and has a venting part extending therethrough and having an entrance formed at an inner side surface of the mold frame to adjust a pressure of a space between the display panel and the touch screen panel which is in direct fluid communication with an external space.

2. The display device of claim 1, wherein the venting part has an air hole formed through the mold frame, the air hole extending from the inner side surface to an outer side surface of the mold frame.

3. The display device of claim 2, wherein the air hole has a zigzag shape.

4. The display device of claim 2, wherein the air hole has a serpentine shape.

5. The display device of claim 1, wherein the venting part has an air hole formed through the mold frame, the air hole extending from the inner side surface toward a lower bottom surface of the mold frame.

6. The display device of claim 5, wherein the air hole comprises:

a first straight portion extending from an opening at the inner side surface of the mold frame in a first direction substantially toward an outer side surface of the mold frame;

a first bent portion connecting the first straight portion to a second straight portion, the second straight portion extending from the first bent portion in a second direction substantially perpendicular to the first direction downward toward the bottom surface of the mold frame;

a second bent portion connecting the second straight portion to a third straight portion, the third straight portion extending from the second bent portion in the first direction;

a third bent portion connecting the third straight portion to a fourth straight portion, the fourth straight portion extending from the third bent portion in the second direction;

a fourth bent portion connecting the fourth straight portion to a fifth straight portion, the fifth straight portion extending from the fourth bent portion in a third direction substantially opposite to the first direction; and

a fifth bent portion connecting the fifth straight portion to a sixth straight portion, the sixth straight portion extending from the fifth bent portion in the second direction to an opening at the bottom surface of the mold frame.

7. The display device of claim 5, wherein the air hole has a serpentine shape.

8. The display device of claim 1, wherein the venting part comprises:

an expansion space formed in the mold frame;

a first air hole formed from the expansion space to an outer side surface of the mold frame; and

a second air hole formed from the expansion space to an inner side surface of the mold frame.

9. The display device of claim 8, wherein a width of the expansion space is greater than a width of the first air hole and a width of the second air hole.

10. The display device of claim 8, wherein the venting part further comprises a plurality of first air holes.

11. The display device of claim 1, wherein the venting part further comprises a porous venting portion formed through the mold frame from an inner side surface of the mold frame to an outer side surface of the mold frame.

12. The display device of claim 11, wherein the porous venting part further comprises a foam resin or a porous fabric.

13. The display device of claim 1, wherein the receiving container further comprises:

a mold frame which supports the display panel;

a chassis member on the mold frame to support the touch screen panel;

a first adhesive member interposed between the mold frame and the chassis member; and

a second adhesive member interposed between the chassis member and the touch screen panel.

14. The display device of claim 13, wherein the venting part comprises an air hole formed through the first adhesive member between the mold frame and the chassis member.

15. The display device of claim 1, further comprising:

a backlight assembly disposed under the display panel to supply the display panel with light; and

a bottom chassis combined with the receiving container to receive the backlight assembly.
