Embodiment 1

[0031] Such as figure 1 As shown, this embodiment provides a polarizer 100 , which includes a substrate 101 , a metal wire grid layer 102 and a transparent layer 103 . Wherein the metal wire grid layer 102 is disposed on the substrate 101, specifically, the metal wire grid layer 102 is prepared on the substrate by nanoimprint technology; the transparent layer 103 is disposed on the metal on the wire grid layer 102 .

[0032] Wherein the metal wire grid layer 102 is provided with a wire grid on the surface away from the substrate 101, and the wire grids are arranged at intervals; specifically, the width range of the wire grid is 50-150 nm, and the wire grid The distance between them is in the range of 50-150nm, and the depth of the wire grid is in the range of 50-150nm. By arranging the wire grids at intervals, a patterned metal wire grid layer 102 is formed, thereby improving the transmittance of the polarizer 100 .

[0033] The material of the metal wire grid layer 102 inc...

Embodiment 2

[0037] Such as figure 2 As shown, this embodiment also provides a liquid crystal display device, which includes: a lower polarizer, a color filter 200 , a liquid crystal 300 and an upper polarizer. The color filter 200 is arranged on the lower polarizer; the liquid crystal 300 is arranged between the lower polarizer and the color filter 200; the upper polarizer is arranged on the color filter 200 on. The lower polarizer and the upper polarizer are both the polarizer 100 described in Embodiment 1. Thus, the transmittance of the liquid crystal display device can be increased, thereby expanding the application scenarios and scope of the liquid crystal display device.

Abstract

The invention relates to a polaroid and a liquid crystal display device. The polaroid comprises a substrate, a metal wire grid layer and a transparent layer. On the one hand, according to the polaroidand the liquid crystal display device, the metal wire grid layer is prepared on the substrate through nano-imprinting technology, and the transparent layer is filled on the metal wire grid layer to improve the transmittance of the polaroid; and on the other hand, the polaroid is applied to the liquid crystal display device to improve the penetration rate of the liquid crystal display device.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a polarizer and a liquid crystal display device. Background technique [0002] The display device can convert the data of the computer into various characters, numbers, symbols or intuitive images and display them, and can use keyboard and other input tools to input commands or data into the computer, and add, delete, modify and change the display at any time with the help of the system's hardware and software. content. Display devices are classified into plasma, liquid crystal, light emitting diode, and cathode ray tube according to the display device used. [0003] The working principle of CRT (abbreviation for Cathode Ray Tube) cathode ray tube display is that the filament heats up after being energized, the cathode is excited, and the electron flow is emitted. The electron flow is accelerated by the internal metal layer with high voltage, and is formed by lens focusing The...
