Patent ID: 7787168

Claim:
A display device, comprising: a plurality of pixels, each pixel comprising a first sub-pixel, a second sub-pixel, a third sub-pixel, and a fourth sub-pixel; a thin film transistor disposed in each sub-pixel; a first color filter disposed in a first sub-pixel region adjacent to the thin film transistor in the first sub-pixel, a second color filter disposed in a second sub-pixel region adjacent to the thin film transistor in the second sub-pixel, and a third color filter disposed in a third sub-pixel region adjacent to the thin film transistor in the third sub-pixel; a planarization layer disposed on the first color filter, the second color filter, and the third color filter; and a pixel electrode connected to each thin film transistor, wherein a color filter and the planarization layer are not disposed in a fourth sub-pixel region adjacent to the thin film transistor in the fourth sub-pixel.
