Abstract

The invention discloses a display panel and a display device, which relate to the field of display technology, having a display area and a non-display area surrounding the display area, including: a base substrate, a common electrode layer, a first passivation layer, and a pixel electrode arranged in sequence layers and an alignment film; the pixel electrode layer includes a plurality of pixel electrodes arranged in an array along the first direction and the second direction, and the common electrode layer includes a common electrode; the first passivation layer includes a plurality of first hollow parts, and the first hollow The part exposes at least part of the common electrode, and the first hollow parts are all located in the display area; in the display area, along the first direction, at least one first hollow part is provided on one side of at least part of the pixel electrodes; the alignment film passes through the first hollow part in contact with the common electrode. The invention solves the problem that charged ions are easily gathered on the surface of the alignment film in the display panel in the prior art.

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...
