Abstract
A liquid crystal display comprises a plurality of pixels, each pixel comprising three or more sub-pixels. A first sub-pixel of the three or more sub-pixels comprises a first transmissive part that has a first transmissive area, and a first reflective part having a first reflective area. A second sub-pixel comprises a second transmissive part that has a second transmissive area, and a second reflective part that has a second reflective area. A third sub-pixel comprises a third transmissive part that has a third transmissive area, and a third reflective part that has a third reflective area. At least two among the first transmissive area, the second transmissive area, and the third transmissive area are different in size. The first reflective area, the second reflective area, and the third reflective area are equal in size.
