OLED显示基板及其制作方法、显示装置及掩模板
摘要：
本发明涉及显示技术领域，公开了一种OLED显示基板及其制作方法、显示装置和一种掩模板。OLED显示基板包括衬底基板以及形成于衬底基板之上的多个像素单元，每个像素单元包括位于衬底基板之上的第一电极、位于第一电极之上的有机发光层和位于有机发光层之上的第二电极，多个像素单元的第二电极相连接，OLED显示基板还包括位于多个像素单元的第二电极之上的电极增厚层，电极增厚层包括第一增厚部和第二增厚部，第一增厚部与OLED显示基板的边缘区域位置相对，第二增厚部位于相邻两个像素单元之间。相比现有技术，该方案提高了OLED显示产品的显示品质和电学特性。
摘要（英）：

The invention relates to the technical field of display, and discloses an OLED display substrate and a manufacturing method thereof, a display device and a mask plate. The OLED display substrate comprises a base substrate and multiple pixel units formed on the base substrate. Each pixel unit comprises a first electrode disposed on the base substrate, an organic light emitting layer disposed on the first electrode, and a second electrode disposed on the organic light emitting layer. The second electrodes of the multiple pixel units are connected. The OLED display substrate further comprises an electrode thickening layer on the second electrodes of the multiple pixel units. The electrode thickening layer consists of a first thickening part and a second thickening part, the first thickening part corresponds to the edge region of the OLED display substrate, and the second thickening part is disposed between two adjacent pixel units. Compared with the prior art, the display quality and electrical characteristic of OLED display products are improved through the scheme.
