ABSTRACT:
A color filter (401) for a transflective liquid crystal display (LCD) includes a transparent substrate (4011), a color filter layer (4012) covering the transparent substrate, a transparent electrode (4013) covering the color filter layer, and a transparent layer (4014). The color filter layer comprises a plurality of color units (4015). Each color unit has a first overlapping portion (4015a), a second overlapping portion (4015b) and a middle portion (4015c) therebetween, and the first overlapping portions of color units are formed on second overlapping portions of contiguous color units to form a plurality of light blocking areas, the middle portion of each color unit has a first portion (r) that corresponds to a reflective mode, and a second portion (t) that corresponds to a transmissive mode. The second portion is thicker than the first portion. A transflective LCD using the color filter is also described.
