Liquid crystal display

The utility model provides a liquid crystal display, belongs to the technical field of display, and aims to solve the problem that the display effect of the liquid crystal display is affected due to light leakage of the liquid crystal display. An electrochromic layer in the liquid crystal display is integrally arranged between a backlight source and a second polaroid; the electrochromism layer comprises an electrochromism unit, and the electrochromism driving circuit is used for controlling the electrochromism unit to change color so as to block light emitted by the backlight source. The liquid crystal display is used for displaying patterns, the electrochromic layer of the liquid crystal display is integrally arranged between the backlight source and the second polaroid, errors generated when the electrochromic layer is attached to the adjacent layer can be avoided, the attaching degree between the electrochromic layer and the adjacent layer can be improved, then the light leakage problem is prevented, and t
