LCD DEVICE

摘要

An LCD device is provided. The LCD device includes a blue backlight source, a lower polarizer, an array substrate, a liquid-crystal layer, an upper substrate, an upper polarizer, and a quantum excitation color filter layer. The LCD device is capable of emitting colored natural light by disposing the blue backlight source which has blue planar light with three wavelengths, improves luminous efficiency of the LCD device, and increases a viewing angle of the LCD device.

主权项

1. A liquid crystal display (LCD) device, comprising:
a blue backlight source utilized to emit a blue planar light; a lower polarizer utilized to transform the blue planar light into a blue polarized light; an array substrate utilized to rotate liquid-crystal molecules in a liquid crystal layer; the liquid crystal layer utilized to modulate a part of the blue polarized light passing through the array substrate according to driving signals; an upper substrate utilized to form a space with the array substrate for keeping the liquid crystal layer; an upper polarizer utilized to obstruct the blue polarized light which is not modulated; and a quantum excitation color filter layer utilized to transform the blue polarized light which passes through the upper polarizer into a planar light comprising multicolored patterns; wherein the blue planar light comprises a first blue planar light with a first wavelength, a second blue planar light with a second wavelength, and a third blue planar light with a third wavelength; the lower polarizer is disposed on an exterior surface of the array substrate; the upper polarizer is disposed on an exterior surface of the upper substrate.
