Document Type and Number:
WIPO Patent Application WO/2022/217690
Kind Code:
A1
Abstract:
Disclosed in the present application are a polarizer and a display device. The polarizer is fixed on one side of a display panel, and comprises a polarizing layer and at least one functional layer stacked with the polarizing layer. A light absorber is added to the functional layer to reduce the transmittance of light having a preset wavelength. The present application can effectively solve the problem that color temperature of the display panel is greatly reduced after the display panel is irradiated by the light having the preset wavelength, and improves a viewing angle, color cast and dark state light leakage.
