Abstract:
A liquid crystal display device which can obviate color mixing of colors when a display screen is viewed from oblique directions while enhancing a numerical aperture of a pixel is provided. In a liquid crystal display device having red sub pixels, green sub pixels and blue sub pixels, a width of a light blocking film arranged on a boundary portion between the blue sub pixel and the sub pixel of other color is set larger than a width of a light blocking film arranged on a boundary portion between the red sub pixel and the green sub pixel.
