Abstract

The present disclosure relates to a display device and an OLED display panel thereof. The OLED display panel includes a substrate, a first OLED pixel unit and a second OLED pixel unit, an encapsulation layer, a polarizer, and a cover plate, in which an opening of the polarizer between the cover plate and the encapsulation layer is filled with a transparent filler. In a first aspect of the present disclosure, the first OLED pixel unit and the second OLED pixel unit are respectively arranged in a transparent display area and a non-transparent display area, so that when the first OLED pixel unit and the second OLED pixel unit are driven, the transparent display area and the non-transparent display area form a full screen; when the first OLED pixel unit is not driven, the transparent display area performs a light-transmission function.
