Abstract

A transflective and non-rectangular display panel and a display device are provided. The non-rectangular display panel includes a display region, a non-display region surrounding the display region, multiple pixels including multiple sub pixels, and a light shielding layer. There is a first boundary between the display region and the non-display region, and a region surrounded by the first boundary and the display region is non-rectangular. Each of the multiple pixels includes at least three of the multiple sub pixels. An open region of each of the multiple sub pixels has a transmissive region and a reflective region. The multiple pixels include normal pixels in the display region and abnormal pixels passed through by the first boundary. In each of the abnormal pixels, each of the transmissive region and the reflective region is partially blocked by the light shielding layer and partially emits light therefrom.
