(EN) DISPLAY PANEL AND METHOD FOR MANUFACTURING SAME
(FR) PANNEAU D'AFFICHAGE ET SON PROCÉDÉ DE FABRICATION
(ZH) 一种显示面板及其制作方法
Abstract
(EN) Provided are a display panel and a method for manufacturing same. The display panel comprises: a thin film transistor array substrate; an anode, wherein the anode is arranged on the thin film transistor array substrate; a pixel definition layer, wherein the pixel definition layer is arranged on the anode, and the pixel definition layer comprises a first area and a second area, the first area being provided with an opening, and the second area being provided with a plurality of recesses; a light-emitting layer, wherein the light-emitting layer is arranged in the opening; a cathode, wherein the cathode covers the light-emitting layer and the pixel definition layer; and an encapsulation layer, wherein the encapsulation layer covers the cathode.
(FR) L'invention concerne un panneau d'affichage et son procédé de fabrication. Le panneau d'affichage comprend : un substrat de réseau de transistors en couches minces ; une anode disposée sur le substrat de réseau de transistors en couches minces ; une couche de définition de pixels disposée sur l'anode, et comprenant une première zone et une seconde zone, la première zone étant pourvue d'une ouverture, et la seconde zone étant pourvue d'une pluralité d'évidements ; une couche électroluminescente disposée dans l'ouverture ; une cathode recouvrant la couche électroluminescente et la couche de définition de pixels ; et une couche d'encapsulation recouvrant la cathode.
(ZH) 本发明提供一种显示面板及其制作方法,包括:薄膜晶体管阵列基板;阳极,阳极设置在薄膜晶体管阵列基板上;像素定义层,像素定义层设置在阳极上,像素定义层包括第一区域和第二区域,其中,第一区域设置有开口,第二区域设置有多个凹槽;发光层,发光层设置于开口内;阴极,阴极覆盖发光层和像素定义层;封装层,封装层覆盖阴极。
