Title
(EN) DISPLAY PANEL AND MANUFACTURING METHOD THEREFOR, AND DISPLAY DEVICE
(FR) PANNEAU D'AFFICHAGE ET SON PROCÉDÉ DE FABRICATION, ET DISPOSITIF D'AFFICHAGE
(ZH) 显示面板及其制造方法、显示装置
Abstract
(EN) Provided are a display panel and a manufacturing method therefor, and a display device, relating to the technical field of display. The thickness of a second part of a first electrode of a sub-pixel in the display panel can be relatively large, capable of blocking a light-emitting film layer; light emitted by part of the film layer located above a first part of the first electrode is transmitted to the area where an adjacent sub-pixel is located, light emitted by the light-emitting film layer in the sub-pixel is prevented from being emitted out of a second electrode of the adjacent sub-pixel, and then crosstalk of light of a plurality of sub-pixels is prevented.
(FR) La présente invention concerne un panneau d'affichage et son procédé de fabrication, et un dispositif d’affichage, se rapportant au domaine technique de l’affichage. L'épaisseur d'une seconde partie d'une première électrode d'un sous-pixel dans le panneau d'affichage peut être relativement grande, capable de bloquer une couche de film électroluminescent ; la lumière émise par une partie de la couche de film située au-dessus d'une première partie de la première électrode est transmise à la zone où se trouve un sous-pixel adjacent, une lumière émise par la couche de film électroluminescent dans le sous-pixel est empêchée d'être émise à partir d'une seconde électrode du sous-pixel adjacent, puis la diaphonie de la lumière d'une pluralité de sous-pixels est empêchée.
(ZH) 提供一种显示面板及其制造方法、显示装置,涉及显示技术领域。该显示面板中子像素的第一电极的第二部分的厚度可以较厚,能够阻挡发光膜层中,位于第一电极的第一部分上方的部分膜层发出的光线传输至相邻子像素所在区域,避免该子像素中的发光膜层发出的光线从相邻子像素的第二电极射出,进而避免多个子像素的光线产生串扰。
