Transreflective LCD having color adjusting windows substantially same size and shape, but different in number in at least 2 different colors
View Patent ↗A liquid crystal display device, by which a reduction of costs of a color filter is realized and declining of the transmittance or reflectance due to an alignment error is suppressed, comprising a pair of substrates arranged facing to each other over a liquid crystal layer, wherein one substrate is formed pixels PXL arranged in matrix. Each pixel is formed a reflection portion for reflecting an outside light and a transmission portion for transmitting a light. The other substrate is formed a color filter colored to be different colors (red, green and blue) corresponding to respective pixels. One or more color adjusting windows CFW having a coloring concentration of zero or less than that of other portions are provided on reflection regions CFR superposing with reflection portions inside pixel regions corresponding to respective pixels.
1. A liquid crystal display device, comprising a first substrate and a second substrate arranged facing each other with a liquid crystal layer therebetween,
pixels arranged in a matrix, and each pixel comprises a reflection portion to reflect light and a transmission portion to transmit light; and
a color filter is secured to the second substrate for coloring respective pixels to be different colors;
wherein each of a plurality of pixels has one or more color adjusting windows located at the reflection portion of the pixel through which light passes without passing through a color filter material of the remaining portions of the pixel, wherein each color adjusting window is formed to be of substantially a same size and shape and a number of color adjusting windows located within a pixel is different for pixels of at least two different colors and at least one pixel has a plurality of color adjusting windows separately provided in the single pixel.
