Abstract
A display device is provided. A liquid crystal display panel has a first display area and a second display area. When the display device displays, a brightness of the first display area is lower than a brightness of the second display area. The liquid crystal display panel includes a pixel electrode, a common electrode, and an insulating layer disposed between the pixel electrode and the common electrode. A thickness of at least part of the insulating layer in the first display area is greater than a thickness of at least part of the insulating layer in the second display area.
