Abstract
A wire grid polarizer and a display panel using the same are provided. The wire grid polarizer includes a substrate, a plurality of wire grids, a plurality of patterned light absorbing layers, and a surface covering layer. The plurality of wire grids are disposed on the substrate, wherein there are a plurality of gaps between every two wire grids. The plurality of patterned light absorbing layers are disposed corresponding to and overlapping the wire grids respectively, wherein every two of the patterned light absorbing layers have one of the gaps. The surface covering layer is disposed on the patterned light absorbing layers and directly contacts the patterned light absorbing layers.
