Abstract
A transreflective liquid crystal display comprises a plurality of pixels. Each pixel includes at least four subpixels including a white subpixel, a red subpixel, a green subpixel and a blue subpixel. Each subpixel comprises a transmissive area and a reflective area. The reflective area of the white subpixel is smaller than that of each of the R, G, and B subpixels so that the percentages of effective output light of the white subpixel and the other colored subpixels are consistent in both reflective and transmissive modes.

A transreflective liquid crystal display, comprising:
- a substrate;
- a plurality of pixels formed on the substrate, each pixel comprising a first subpixel and a second subpixel, wherein each of the subpixels comprises a transmissive area and a reflective area, and the reflective area of the first subpixel is smaller than that of the second subpixel;
- and
- a color filter including a plurality of colored regions respectively above the second subpixels and a plurality of uncolored regions respectively above the first subpixels.
A transreflective liquid crystal display, comprising:
- a plurality of pixels, each pixel comprising a red subpixel, a green subpixel, a blue subpixel and a white subpixel, each of the four subpixels including a transmissive area and a reflective area;
- and a color filter comprising red regions, green regions, blue regions and uncolored regions, one of the red regions, the green regions and the blue regions including a uncolored block located above one of the reflective areas.
