Display panel and display device

Abstract

The invention discloses a display panel and a display device, and relates to the technical field of display. The display panel comprises a display area, the display area comprises a first display area and a second display area, and the light transmittance of the second display area is greater than that of the first display area. The display panel comprises a first substrate, a second substrate and liquid crystal arranged between the first substrate and the second substrate, wherein the first substrate and the second substrate are oppositely arranged. The first substrate comprises an underlayment and a first insulating layer which is arranged on the underlayment and faces the second substrate; a first electrode and a second electrodes which are arranged on the side, facing the second substrate, of the first insulating layer, and are isolated by the second insulating layer in the direction perpendicular to the underlayment. In the second display area, a plurality of grooves are formed in the surface, facing the second substrate, of the first insulating layer and / or the second insulating layer, and the first electrodes and the second electrodes are overlapped with the grooves in the direction perpendicular to the underlayment. Therefore, the possibility of diffraction in the second display area is reduced, and the imaging effect of the second display area is improved.

Description

technical field

[0001] The present invention relates to the field of display technology, and more specifically, to a display panel and a display device. Background technique

[0002] With the development of display technology, display panels have higher and higher screen-to-body ratios, and full screens have attracted widespread attention due to their narrow-frame or even frame-less display effects. At present, display devices such as mobile phones and tablet computers often need to reserve space for electronic photosensitive devices such as commonly used front cameras, infrared sensing devices, and fingerprint recognition devices. For example, these photosensitive devices are arranged at the top of the front of the display device, and the corresponding position forms a non-display area, thereby reducing the screen-to-body ratio of the device.

[0003] In the prior art, in order to increase the screen-to-body ratio, a high light transmission area may be provided in the disp...
