Abstract

The invention discloses an array substrate and a display panel including the same. The array substrate comprises a substrate base plate, a planarized layer arranged on the substrate base plate, and multiple pixel electrodes arranged on the planarized layer. A groove is arranged between any two adjacent pixel electrodes in the planarized layer, and the depth of the groove is smaller than the depth of the planarized layer. According to the scheme provided by the invention, through arranging the grooves whose depth is smaller than that of the planarized layer between any two adjacent pixel electrodes in the planarized layer, the thickness of a film layer for making a pixel electrode formed at the side face of the groove is smaller than the thickness of film layers for making the pixel electrode formed at other places, at the same time the liquidity of an etching medicine liquid in the groove is poor, thus the etching medicine liquid in the groove can fully react with a contact film layer for making the pixel electrode, and thus a short circuit phenomenon formed by incomplete etching of the film layer for making the pixel electrode between adjacent pixel electrodes is improved.

Description

technical field [0001] The present application generally relates to the field of display technology, and in particular relates to an array substrate and a display panel including the array substrate. Background technique [0002] A display panel usually includes a plurality of pixels, and each pixel usually includes a pixel electrode. The material of each pixel electrode may include indium tin oxide (ITO). When manufacturing a display panel, it is usually necessary to manufacture independent pixel electrodes by etching a film layer including indium tin oxide coated on a base substrate. [0003] In the process of etching the film layer including indium tin oxide to make each independent pixel electrode by etching process, the etching may be incomplete, and the partially etched indium tin oxide will make the adjacent two pixels A short circuit occurs between them, causing adjacent pixels that should not emit light to emit light, resulting in poor display of the display panel...
