Liquid crystal display

摘要

A liquid crystal display (LCD) is provided and includes an liquid crystal panel, a diffraction plate, a first polarizer, a second polarizer, a first brightness enhancement film (BEF), and a second BEF. The diffraction plate is disposed on a first surface of the liquid crystal panel and has a diffractive direction. The first polarizer is disposed between the diffraction plate and the liquid crystal panel and has a first absorption axis. The second polarizer is disposed on a second surface of the liquid crystal panel opposite to the first surface and has a second absorption axis perpendicular to the first absorption axis. The first BEF has a first light-collecting direction. The second BEF has a second light-collecting direction perpendicular to the first light-collecting direction. The first light-collecting direction is parallel or perpendicular to the diffractive direction or the first absorption axis.

1. A liquid crystal display, comprising:
a liquid crystal panel comprising a liquid crystal layer, a diffraction plate disposed on a first surface of the liquid crystal panel, wherein the diffraction plate includes a plurality of grating regions having at least one first diffractive direction and a plurality of space regions located between the grating regions, and the space regions have no grating and are transparent; a first brightness enhancement film disposed on a second surface of the liquid crystal panel, wherein the first brightness enhancement film having a first light-collecting direction, and the second surface is opposite to the first surface of the liquid crystal panel; wherein an included angle between the first diffractive direction and the first light-collecting direction is in a range from −110 degrees to −65 degrees or from −30 degrees to 20 degrees and excluding 0 degree and −90 degrees.
