Abstract

A display device is provided with a display panel displaying variable visual images, a transparent protective unit located at a front side of the display panel, an adhesive layer that is formed between the display panel and the transparent protective unit to adhere the transparent protective unit to the display panel, and a fixing member disposed at a rear side of the display panel and surrounding and fixing side surfaces of the display panel and the adhesive layer.

Claims

1. A display device, comprising:

a display panel displaying variable visual images;

a transparent protective unit located at a front side of the display panel;

an adhesive layer formed between the display panel and the transparent protective unit to adhere the transparent protective unit to the display panel; and

a fixing member disposed at a rear side of the display panel and surrounding and fixing side surfaces of the display panel and the adhesive layer.

2. The display device of claim 1, comprised of the adhesive layer being made from a transparent synthetic resin.

3. The display device of claim 1, comprised of the adhesive layer having a thickness of approximately 0.15 mm to approximately 0.25 mm.

4. The display device of claim 1, comprised of the fixing member comprising a bottom portion contacting a rear surface of the display panel, and a guide portion extending from an edge of the bottom portion toward the transparent protective unit and contacting side surfaces of the display panel and adhesive layer.

5. The display device of claim 4, comprised of the guide portion having a greater height than a sum of thicknesses of the display panel and the adhesive layer.

6. The display device of claim 5, comprised of the transparent protective unit having the same size as the adhesive layer, and the side surface of the transparent protective unit contacting the guide portion.

7. The display device of claim 4, comprised of the guide portion having the same height as a sum of thicknesses of the display panel and the adhesive layer.

8. The display device of claim 7, comprised of the transparent protective unit having a greater width than that of the adhesive layer, and a part of a rear surface of the transparent protective unit contacting the top surface of the guide portion.

9. The display device of claim 4, comprised of the guide portion being provided with at least one opening through which bubbles that are generated during the formation of the adhesive layer are discharged.

10. The display device of claim 9, comprised of the guide portion has a pair of long sides and a pair of short sides, and the openings being located on one of the short sides and on both of the long sides.

11. The display device of claim 1, comprised of the display panel comprising a front substrate and a rear substrate, a polarizing film being located on a front surface of the front substrate, and the adhesive layer having the same refractive index as the transparent protective unit.

12. The display device of claim 1, comprised of the display panel comprising a front substrate and a rear substrate, a polarizing film being located on a front surface of the transparent protective unit, and the adhesive layer having a same refractive index as the transparent protective unit and the front substrate.

13. The display device of claim 1, comprised of the display panel being an organic light emitting diode display.
