  • Patent number: 9261727
    Abstract: A liquid crystal display includes a liquid crystal display panel including pixels and a backlight unit disposed at a rear side of the liquid crystal display panel to supply first and second color lights having different wavelengths to the liquid crystal display panel. In each pixel, first and second color filters having first and second colors different from each other are sequentially arranged in a first direction. Each pixel also includes a first open portion allowing the first and second color filters to be spaced apart from each other in the first direction and a second open portion allowing the second color filter to be spaced apart from a color filter of an adjacent pixel in the first direction. The backlight unit supplies the first and second color lights to the liquid crystal display panel during first and second sub-fields obtained by dividing a frame.
