Abstract:
1. A liquid crystal display device comprising: a plurality of pixels that are arranged in rows and columns so as to form a matrix pattern; and TFTs, source bus lines, gate bus lines and CS bus lines, which are associated with the respective pixels, wherein each said pixel includes at least three subpixels with liquid crystal capacitors that are able to retain mutually different voltages, wherein by supplying a signal that makes two of the at least three subpixels display mutually different luminances at least at a certain grayscale tone from the source, gate and CS bus lines to each said pixel, the at least three subpixels are able to display mutually different luminances; wherein each said pixel is associated with at least three TFTs for the at least three subpixels, one source bus line, at least one gate bus line and at least two CS bus lines, wherein each of the TFTs associated with the at least three subpixels includes a gate electrode, a source electrode and a drain electrode; wherein when the at least three subpixels are comprised of first, second and third subpixels and the at least two CS bus lines are comprised of first and second CS bus lines, the first subpixel has a storage capacitor that is connected to the first CS bus line, the second subpixel has a storage capacitor that is connected to the second CS bus line, and the third subpixel has a storage capacitor that is connected to the first CS bus line and a storage capacitor that is connected to the second CS bus line; and wherein the pixels include a red pixel to represent the color red, a blue pixel to represent the color blue, and a green pixel to represent the color green, and wherein the blue pixel has a narrower cell gap than the red pixel or the green pixel.
