Abstract
The present invention provides an OLED display screen and a manufacturing method thereof. The OLED display screen includes a substrate, a functional layer, and a polarizing layer including a photoresist layer. A concave-convex structure is disposed on a surface of the polarizing layer facing away from the functional layer. The manufacturing method of the OLED display screen includes the steps: forming a display panel and forming a polarizing layer. The invention adopts the polarizing layer instead of a polarizer, and designs the concave-convex structure on the surface of the polarizing layer, thereby reducing reflectance of the surface of the polarizing layer and improving light emitting rate of the light emitting layer. Moreover, the concave-convex structure can change light angles and increase viewing angles, thereby improving narrow viewing angles of current OLED display screens and issues affecting readability, and improving readability of OLED display screens under outdoor sunlight.
