An embodiment of the present invention relates to a liquid crystal display. An upper surface alignment layer in the liquid crystal display is arranged to comprise, in the direction from a color filter substrate to a liquid crystal layer, a first upper surface alignment layer, a color washout compensation film layer and a second upper surface alignment layer; an alignment direction of the color washout compensation film layer is opposite to the pre-alignment direction of the liquid crystal layer. In the technical solution, the color washout compensation film layer is used to rectify the color washout problem occurring when the screen of a liquid crystal display screen of a fringe field switching mode is viewed from both the left side and right sides.
