摘要:
Disclosed herein is a liquid crystal display that compensates an hourglass phenomenon using a backlight unit. The liquid crystal display includes a liquid crystal panel, a polarizer adhered to the liquid crystal panel, and a backlight unit including a diffuser sheet. A predetermined region of the diffuser sheet facing a region of the polarizer, where an hourglass phenomenon occurs, is formed to permit a smaller quantity of light to be transmitted therethrough than other regions of the diffuser sheet. With this construction, the liquid crystal display can avoid the hourglass phenomenon from being observed by a viewer, and prevent non-uniform brightness while improving image quality.
