Metal wire grid polarizing film and liquid crystal display device

Abstract

The invention provides a metal wire grid polarizing film and a liquid crystal display device. The metal wire grid polarizing film comprises blue light quantum dots, the blue light emitted by blue light quantum dots is used to compensate the problem of the low transmission rate of the metal wire grid polarizing film in a blue light area, the color cast of the liquid crystal display device is prevented, and the display quality of the liquid crystal display device is improved. According to the liquid crystal display device of the invention, through arranging the blue light quantum dots in the metal wire grid polarizing film or individually arranging a blue light quantum dot film layer in the liquid crystal display device, the blue light quantum dots can absorb the UV light and blue violet light of the short wave high energy emitted by a blue light emitting diode, the light utilization rate of a back light source can be improved, the damage to eyes by the UV light and blue violet light with short wavelengths can be avoided, at the same time, the blue light emitted by the blue light quantum dots can compensate the problem of the low transmission rate of the metal wire grid polarizing film in the blue light area, the color cast of the liquid crystal display device is prevented, and the display quality of the liquid crystal display device is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a metal wire grid polarizer and a liquid crystal display device. Background technique [0002] With the development of science and technology and the progress of society, people are increasingly dependent on information exchange and delivery. As the main carrier and material basis of information exchange and transmission, display devices, especially Liquid Crystal Display (LCD), have become the focus of more and more people's attention, and are widely used in all aspects of work and life. [0003] For a liquid crystal display device, a backlight source is an essential part thereof. Generally speaking, the backlight of a liquid crystal display device uses blue light emitted by a blue light-emitting diode (LED, Light Emitting Diode) to excite yttrium aluminum garnet (YAG) phosphors, which form white light after modulation. The blue light emitted by ordinary blue light-emitting d...
