Abstract

A display device is provided. The display device includes a display panel configured to output a screen, at least one optical member configured to make the screen output from the display panel pass therethrough, and an optical attachment layer configured to attach the optical member to the display panel. The optical attachment layer is colored and transparent.

Claims

1. A display device comprising:

a display panel configured to output a screen;

at least one optical member configured to make the screen output from the display panel pass therethrough; and

an optical attachment layer configured to attach the optical member to the display panel,

wherein the optical attachment layer is colored and transparent.

2. The display device of claim 1, wherein the optical attachment layer is configured to be made of a Pressure Sensitive Adhesive (PSA).

3. The display device of claim 1, wherein the optical attachment layer is configured to be an optical adhesive film.

4. The display device of claim 1, wherein the optical attachment layer is configured to transmit light having a wavelength ranging from 380 nm to 800 nm.

5. The display device of claim 1, wherein the optical member is configured to be a polarizing film which is made of polyvinyl alcohol.

6. The display device of claim 5, wherein the optical attachment layer is configured to be made of a Pressure Sensitive Adhesive (PSA).

7. The display device of claim 6, further comprising a protective film disposed on at least one surface of the optical member and interposed between the optical member and the optical attachment layer.

8. The display device of claim 7, further comprising a surface coating layer formed on at least one other surface of the optical member.

9. The display device of claim 8, wherein the surface coating layer is configured to be at least one of a hard coating layer, an anti-reflective coating layer, a low-reflective coating layer, and an anti-glare coating layer.

10. The display device of claim 1, wherein the optical member is configured to be an Indium-Tin Oxide (ITO) film that provides a touch screen function.

11. The display device of claim 10, wherein the optical attachment layer is configured to be an optical adhesive film.

12. The display device of claim 1, wherein the optical attachment layer includes a color additive in order to be colored and transparent.

13. The display device of claim 1, wherein the display panel is configured to be a Liquid Crystal Display (LCD) panel, and

wherein a white balance is set by a color combination of light emitted from the light source provided adjacent to the display panel and light emitted from the optical member.

14. The display device of claim 1, wherein the display panel is configured to be made of an Organic Light Emitting Diode (OLED), and

wherein a white balance is set by a color combination of light emitted from a phosphor of the display panel and the color of the optical attachment layer.

15. A display device comprising:

a display panel configured to output a screen;

at least one optical member disposed on the display panel, the at least one optical member being transparent to the screen output from the display panel; and

an optical attachment layer disposed between the optical member and the display panel,

wherein the optical attachment layer is colored so as to have a color tint.

16. The display device of claim 15, wherein the optical member is configured to be an Indium-Tin Oxide (ITO) film that provides a touch screen function.

17. The display device of claim 15, wherein the optical attachment layer is configured to be one of an optical adhesive film and a Pressure Sensitive Adhesive (PSA).

18. The display device of claim 15, wherein the optical attachment layer is configured to be transparent to light having a wavelength ranging from 380 nm to 800 nm.

19. The display device of claim 15, wherein the display panel is configured to be a Liquid Crystal Display (LCD) panel,

wherein the display device further comprises a light guide plate disposed below the display panel and a light source providing light to the light guide plate, and

wherein a white balance is set by a color combination of light emitted from the light source provided adjacent to the display panel and light emitted from the optical member.

20. The display device of claim 15, wherein the display panel is configured to be made of an Organic Light Emitting Diode (OLED), and

wherein a white balance is set by a color combination of light emitted from a phosphor of the display panel and the color of the optical attachment layer.
