Abstract

A liquid-crystal display panel includes a first region and a second region, and a transmittance of the first region is greater than a transmittance of the second region; the liquid-crystal display panel includes a plurality of sub-pixels; the plurality of sub-pixels include a first-color sub-pixel and a second-color sub-pixel, a transmittance of the first-color sub-pixel is greater than a transmittance of the second-color sub-pixel, and an area of the first-color sub-pixel is greater than an area of the second-color sub-pixel; and the plurality of sub-pixels further include a first-region sub-pixel and a second-region sub-pixel that have a same color, the first-region sub-pixel is located within the first region, the second-region sub-pixel is located within the second region, and a thickness of a color-resistance layer of the first-region sub-pixel is less than or equal to a thickness of a color-resistance layer of the second-region sub-pixel.
