Document Type and Number:
WIPO Patent Application WO/2010/061577
Kind Code:
A1
Abstract:
A multiple primary color liquid crystal display device in which a plurality of red sub-pixels are provided per pixel, and which has improved viewing angle characteristics.
The multiple primary color liquid crystal display device comprises a pixel defined by a plurality of sub-pixels, and performs color display using four or more primary colors displayed by the plurality of sub-pixels. The plurality of sub pixels of the multiple primary color liquid crystal display device include first and second red sub-pixels (R1, R2) which display red, a green sub-pixel (G) which displays green, a blue sub-pixel (B) which displays blue, and a cyan sub-pixel (C) which displays cyan. When a color with a hue within a predetermined first range is displayed by the pixel, the gradation level of the first red sub-pixel (R1) and the gradation level of the second red sub-pixel (R2) differ from each other. When a color with a hue within a second range different from the first range is displayed by the pixel, the gradation level of the first red sub-pixel (R1) and the gradation level of the second red sub-pixel (R2) are the same.
