摘要: A liquid crystal display has a panel, backlight and dark layer. The panel an upper polarizer, cell, lower the two polarizers both have wide view optical compensation films. light emitted from is transmitted to viewer through sequentially. layer of invention placed between viewer, it lowers dark-state brightness improve downward angle contrast ratio thereof be greater than 10.
