Abstract: A display panel and a display device are provided. The display panel includes a display area including a transparent display area and an opaque display area surrounding the transparent display area. In the display area, the display panel also includes a backlight and a liquid crystal display panel. The backlight includes a first through hole corresponding to the transparent display area. The liquid crystal display panel is disposed over the backlight. The liquid crystal display panel includes a driving layer and a liquid crystal layer. The driving layer includes a first driving circuit and a second driving circuit. The liquid crystal layer includes a first liquid crystal region corresponding to the transparent display area and a second liquid crystal region corresponding to the opaque display area. The first driving circuit corresponds to the first liquid crystal region. The second driving circuit corresponds to the second liquid crystal region.

Abstract: A display panel and a display device are provided. The display panel includes a display area including a transparent display area and an opaque display area surrounding the transparent display area. The display panel further includes a first substrate layer, a luminous layer, a liquid crystal layer, a first driving layer, and a second driving layer. The display panel is divided into the transparent display area and the opaque display area by combining an organic light-emitting diode technology and a liquid crystal display technology, such that the transparent display area can provide a light channel for a camera and can also display an image, thereby improving a screen-to-body ratio and realizing a real full-screen display.
