Abstract

A display panel and a display apparatus are provided. The display panel includes a display area. The display area includes color pixels and pixel groups. The color pixels include a first pixel, a second pixel and a third pixel that have different colors from one another, each of the pixel groups includes one first pixel, one second pixel, one third pixel and at least one color-changing pixel. An operating state of the at least one color-changing pixel includes a transparent state and a black state. The display panel provided by the present disclosure can achieve a transparent display effect, and can also display black pixel information in an image by using a black state of the color-changing pixel, which solves the technical problem in the related art in which transparent display is difficult to display black pixel information in the image.
