Abstract
An organic light-emitting diode (OLED) display panel and a method of manufacturing the same are disclosed. The OLED display panel includes a base substrate and a plurality of film layers sequentially deposited on a side of the base substrate in a stacked arrangement in a first direction. The plurality of film layers includes a first planarization layer configured to initially planarize an array substrate, and a second planarization layer configured to further planarize the array substrate. The first planarization layer and the second planarization layer are made of different materials.
