Abstract

A display panel and a display device are provided. The display panel has a display area including a conventional display region and a translucent display region; and a non-display area. First sub-pixels, second sub-pixels and third sub-pixels are provided in the conventional display region, the first sub-pixels are arranged in a first density, and the second and third sub-pixels are arranged in a second density. Fourth sub-pixels, fifth sub-pixels and sixth sub-pixels are provided in the translucent display region, the fourth sub-pixel has a same color as the first sub-pixel, the fifth sub-pixel has a same color as the second sub-pixel, and the sixth sub-pixel has a same color as the third sub-pixel. The fourth sub-pixels are arranged in a third density equal to the first density, the fifth and sixth sub-pixels are arranged in a fourth density. The second density is greater than the fourth density.
