Liquid crystal display device
View Patent ↗To provide a liquid crystal display device to suitably perform color balance adjustment. For this, the liquid crystal display device includes pixel regions each including a light reflection portion and a light transmission portion on a liquid-crystal-side surface of one substrate out of respective substrates arranged to face each other in an opposed manner while sandwiching liquid crystal therebetween, wherein color filters are formed in pixel regions on a liquid-crystal-side surface of the other substrate out of the respective substrates, and each color filter is provided with an opening or notch at a part of a portion facing the light reflection portion in an opposed manner, material layers having a layer thickness substantially equal to a height of step generated by the color filters in regions facing the opening or notch of each color filter in an opposed manner on the liquid-crystal-side surface of one substrate.
1. A liquid crystal display device comprising pixel regions each of which includes a light reflection portion and a light transmission portion on a liquid-crystal-side surface of one substrate out of respective substrates which are arranged to face each other in an opposed manner while sandwiching liquid crystal therebetween, wherein
color filters of different colors are formed on pixel regions which are disposed close to each other out of pixel regions on a liquid-crystal-side surface of the other substrate out of the respective substrates, and the color filter of at least one color is provided with an opening or a notch at a part of a portion thereof which faces the light reflection portion in an opposed manner, and
at least one of the light transmission portions of respective pixel regions of the color filters of different colors differs in size from the other light transmission portions,
and each said light transmission portion having a length and a first end substantially aligned in the direction of said length with the first ends of said other light transmission portions within each pixel region.
2. A liquid crystal display device according to claim 1 , wherein colors of the respective color filters having different colors are respectively formed of red, green and blue.
3. A liquid crystal display device according to claim 1 , wherein colors of the respective color filters of different colors are respectively formed of cyan, magenta and yellow.
4. A liquid crystal display device according to claim 1 , wherein an area of the light reflection portion of the pixel region on which said color filter of blue color is formed is set larger than an area of the light reflection portion of the pixel region on which the color filter of other color is formed.
5. A liquid crystal display device according to claim 1 , wherein an area of the light reflection portion of the pixel region on which the color filter of yellow color is formed is set smaller than an area of the light reflection portion of the pixel region on which the color filter of other color is formed.
6. A liquid crystal display device according to claim 1 , wherein a total area of the opening or the notch depends on the color of the color filter.
7. A liquid crystal display device according to claim 1 , wherein the liquid crystal display device includes a backlight.
