Abstract

The present disclosure relates to a display panel and a display apparatus. The display panel includes an array substrate, a color filter substrate, a driving chip, and a backlight structure; where the driving chip is electrically connected to the array substrate and is configured to control a voltage signal on the array substrate, the driving chip is disposed at an inner side of the array substrate, and the color filter substrate is located between the array substrate and the backlight structure. In the above structure, the array substrate may be covered on the outer side of the color filter substrate and the driving chip, thereby achieving the protection of the structure at an inner side of the array substrate.
