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 and a non-display area surrounding the display area; the display panel comprises a substrate, a common electrode layer, a first passivation layer, a pixel electrode layer and an alignment film which are sequentially arranged; the pixel electrode layer comprises a plurality of pixel electrodes arranged in an array in the first direction and the second direction; the common electrode layer comprises a common electrode; the first passivation layercomprises a plurality of first hollow-out parts which expose at least part of the common electrodes; the first hollow-out parts are positioned in the display area; at least one first hollow-out partis arranged on one side of at least part of the pixel electrodes in the display area along the first direction; and the alignment film is in contact with the common electrodes through the first hollow-out parts. The problem that in the prior art, the surface of the alignment film in the display panel is easy to gather with ions is solved.

Description

technical field

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

[0002] From the CRT (Cathode Ray Tube, cathode ray tube) era to the liquid crystal era, and to the current OLED (Organic Light-Emitting Diode, organic light-emitting diode) era, the display industry has experienced decades of development and has become ever-changing. The display industry has been closely related to our lives. From traditional mobile phones, tablets, TVs and PCs to the current smart wearable devices and VR, display technology is inseparable.

[0003] The charged ions accumulated on the surface of the alignment film in the display panel are not easy to be guided away. These accumulated charged ions form a built-in electric field in the panel, which is opposite to the direction of the electric field that normally drives liquid crystal molecules in the panel, and it is easy to cause afteri...
