Abstract
The present invention provides a liquid crystal display device which exhibits improved color reproducibility, high definition and a high numerical aperture by minimizing a change of a total area of color filter non-forming regions even when a position of a color filter is displaced. A color filter forming region and the color filter non-forming regions are formed within a lighting region which is visible to a viewer in the inside of one pixel. Further, in the inside of one pixel, a first side of the lighting region includes both of the color filter forming region and the color filter non-forming region, a second side of the lighting region which faces the first side in an opposed manner includes both of the color filter forming region and the color filter non-forming region, the first side assumes the color filter non-forming region at a region which faces the color filter forming region of the second side in an opposed manner, and the second side assumes the color filter non-forming region at a region which faces the color filter forming region of the first side in an opposed manner.
