A wire grid polarizer, its manufacturing method and display panel

Abstract

The invention relates to a wire gating polarizer, a manufacturing method thereof and a display panel. The wire gating polarizer, the manufacturing method thereof and the display panel are used for solving the problem of declined reflectivity of the wire gating polarizer for a metal wire grate of the existed metal wire gating polarizer is very easy to be oxidized or corroded in use. The wire gating polarizer comprises several wire grates arranged on a substrate, wherein the wire grates are aligned in parallel to each other, and space between every two adjacent wire grates is equal; at least one wire grate comprises a wire grate main body and a protecting film coating on the surface of the wire grate main body; the hardness and corrosive resistance of the protecting film material are more than that of the wire grate main body material. The wire grate comprises the wire grate main body and the protecting film coating on the surface of the wire grate main body; for the hardness and corrosive resistance of the protecting film material are more than that of the wire grate main body material, the protecting film can effectively protect the wire grate main body from being oxidized or corroded, and further improve the hardness and wear resistance of the wire grate.

Description

technical field [0001] The invention relates to the technical field of wire grid polarizers, in particular to a wire grid polarizer, a manufacturing method thereof and a display panel. Background technique [0002] The wire grid polarizer is composed of a diffraction grating, which has a function of polarizing the transmitted light. The diffraction grating is arranged in parallel with a wire grid at a period shorter than the wavelength of the light on a substrate made of glass or the like, wherein the wire grid The period of is the sum of the width of the grid and the spacing between the grids. For the light incident from the light source, the wire grid polarizer can reflect back the light parallel to the wire grid, and transmit the light perpendicular to the wire grid direction, that is: the direction perpendicular to the wire grid is the transmission axis, parallel to the The wire grid direction is the reflection axis. [0003] A wire grid polarizer made of metal materia...
