Abstract

一种显示装置、显示面板及其制造方法，显示面板包括衬底(1)、第一绝缘层(2)、第一电极层(3)、像素定义层(4)、发光功能层(5)和第二电极(6)；第一绝缘层(2)设于衬底(1)一侧，第一绝缘层(2)具有阵列分布的多个像素区(202)以及分隔像素区202的分隔区(201)；第一电极层(3)设于第一绝缘层(2)背离衬底(1)的表面，且包括多个第一电极(31)；各第一电极(31)在第一绝缘层(2)的正投影位于各像素区(202)以内；像素定义层(4)设于第一绝缘层(2)背离衬底(1)的表面，且露出各第一电极(31)；像素定义层(4)在对应于分隔区(201)的区域形成有像素定义槽(41)，像素定义槽(41)的中部具有向背离衬底(1)的方向凸起的第一凸起(42)，第一凸起(42)的侧壁与像素定义槽(41)的侧壁之间形成子槽(40)。发光功能层(5)覆盖像素定义层(4)以及被像素定义层(4)露出的第一电极(31)和第一绝缘层(2)；第二电极(6)覆盖发光功能层(5)，从而能够降低尖端放电的风险，减少对相邻子像素的干扰。
