Title
(EN) POLARIZING DEVICE AND METHOD FOR PREPARING THE SAME, DISPLAY SUBSTRATE AND DISPLAY DEVICE
Abstract
(EN)

The present disclosure provides a polarizing device and a method for preparing the same, a display substrate, and a display device. The polarizing device includes: a base substrate, a metal wire grid, and an anti-reflection layer, in which the metal wire grid is arranged on the base substrate, the anti-reflection layer is arranged on the surface of the metal wire grid away from the base substrate, and the anti-reflection layer is a carbon film layer.
