Liquid crystal display device
View Patent ↗The present invention provides a liquid crystal display device which includes a first pixel and a second pixel which are arranged close to each other and are allocated to the same color, and color filters which differ in color tone and are formed on the first pixel and the second pixel, wherein a voltage for driving liquid crystal of the first pixel and a voltage for driving liquid crystal of the second pixel are controlled independently from each other.
1. A liquid crystal display device comprising:
a pixel which is allocated to one color; and
color filters which differ in color tone and are allocated to the same color and are formed on a first divided region and a second divided region of the pixel, wherein
a layer thickness of liquid crystal in the first divided region is set larger than a layer thickness of liquid crystal in the second divided region, and
wherein the first color filter formed in the first divided region and the second color filter formed in the second divided region are formed such that when chromaticity coordinates of color which are observed through a color filter of the same color are changed corresponding to a change from a high gray scale to a low gray scale, a color filter which is specified with coordinates at a starting-point side of movement of the change is formed as the first color filter and a color filter which is specified with coordinates at a terminal-point side of the movement of the change is formed as the second color filter.
2. A liquid crystal display device according to claim 1 , wherein the second divided region is configured as a pixel which compensates the coordinates displacement in CIE chromaticity coordinates of display information from the first divided region.
3. A liquid crystal display device according to claim 1 , wherein the liquid crystal display device is driven in a state that the luminance of the first divided region is set larger than the luminance of the second divided region.
4. A liquid crystal display device according to claim 1 , wherein the respective pixels which constitute a unit pixel for color display and are allocated to respective colors consisting of red, green and blue are formed in a state that the respective pixels are arranged close to each other, and the first divided region and the second divided region are provided to each pixel.
5. A liquid crystal display device according to claim 1 , wherein the respective color filters which differ in color tone differ in coordinates on CIE chromaticity coordinates.
