FLAT PANEL DISPLAY DEVICE

1 . A flat panel display device comprising:

a plurality of sub-pixels for emitting light having different wavelengths; and

an intensity adjusting layer in a light path of at least one sub-pixel from among the plurality of sub-pixels and for adjusting an intensity of light emitted from the at least one sub-pixel.

2 . The device of claim 1 , wherein the intensity adjusting layer is in a light path of each sub-pixel and corresponds to each sub-pixel.

3 . The device of claim 1 , wherein the intensity adjusting layer is configured to adjust the intensity of the light emitted from each sub-pixel at a different ratio.

4 . The device of claim 1 , wherein the intensity adjusting layer is configured to adjust the light emitted from the sub-pixels to have different intensity ratios.

5 . The device of claim 1 , wherein the intensity adjusting layer is configured to adjust the intensity of the light emitted from each sub-pixel so that the light transmitted through the intensity adjusting layer is white light.

6 . The device of claim 1 , wherein the intensity adjusting layer is configured to adjust the intensity of the light at a wavelength of maximum intensity from among the light emitted from each sub-pixel.

7 . The device of claim 1 , wherein the intensity adjusting layer is configured to reduce the intensity of the light emitted from each sub-pixel by a predetermined amount to adjust the intensity of the light.

8 . The device of claim 1 , wherein each sub-pixel comprises an organic light emitting element.

9 . A flat panel display device comprising:
