Abstract
The present application provides a polarizer and a display device. The polarizer is fixed to one side of a display panel. The polarizer includes a polarizing layer and at least one functional layer stacked on the polarizing layer. The functional layer is added with a light absorber to reduce transmittance of light with a predetermined wavelength. This can effectively solve a problem that a color temperature of the display panel drops greatly after irradiation of the light of the predetermined wavelength. The present application also improves viewing angles and relieves color shift and dark-state light leakage.
