Abstract
A polarizer substrate includes a substrate, an organic planarization layer, an inorganic buffer layer, and a plurality of strip-shaped polarizer structures. The organic planarization layer is located on the substrate. The inorganic buffer layer is located on the organic planarization layer. The inorganic buffer layer has a plurality of trenches located on a first surface. The trenches do not penetrate through the inorganic buffer layer. The strip-shaped polarizer structures are located on the first surface of the inorganic buffer layer. Each of the trenches is located between two adjacent polarizer structures. A display panel is also provided.
