## Abstract

A display panel and a display device. The first display region of the display panel includes a first boundary on a side of the display panel, the second display region includes a second boundary on the same side and is connected with the first boundary, and the display panel includes a first pixel unit which is located in the first display region and includes a plurality of first sub-pixels of different colors. A second pixel unit which is located in the second display region and includes a plurality of second sub-pixels of different colors, and dummy sub-pixels which are located in the first display region and between the first pixel unit and the first boundary. A color of the dummy sub-pixels is the same as that of the second sub-pixels in the second pixel unit adjacent to the second boundary.

## Claims
