Patent ID: 8891044

Claim:
A color display device having a matrix array of unit pixel layouts each comprised of four colors of sub-pixels for performing color displaying, wherein each color is made substantially equal in total area while causing an area of sub-pixel and a number thereof to be different on a per-color basis, wherein each sub-pixel includes a single unit sub-pixel or a plurality of unit sub-pixels which are placed adjacent to each other; size of each of the unit sub-pixels is substantially equal each other; said four colors include two colors red (R) and blue (B) with lower visual sensitivity and two colors with higher visual sensitivity; the two colors of sub-pixels with higher visual sensitivity among said four colors of sub-pixels are each constituted from two unit sub-pixels which are not directly adjacent to each other; each of the red (R) sub-pixel and the blue (B) sub-pixel comprises two unit sub-pixels, which are directly adjacent to each other; each of the single unit sub-pixels consists of one color of sub-pixels; each of the two unit sub-pixels included in the red (R) and blue (B) sub-pixels includes a thin-film transistor; two thin-film transistors of the two unit sub-pixels included in the red (R) sub-pixel are connected to a same signal line; and two thin-film transistors of the two unit sub-pixels included in the blue (B) sub-pixel are connected to a same signal line, each of the single unit sub-pixels of the two colors of sub-pixels with higher visual sensitivity among said four colors of sub-pixels includes one thin-film transistor.
