Abstract
An organic light-emitting diode (OLED) display panel and an electronic device are disclosed. The OLED display panel includes a display area having a light-emitting area and a non-light emitting area. The OLED display panel includes a cover. The cover includes a base layer, a color resist layer, a black matrix layer, a planarization layer, and a first optical compensation layer. The first optical compensation layer is located corresponding to the black matrix layer.
