Abstract

一种显示基板以及显示装置。显示基板中的子像素包括发光元件以及像素电路，发光元件包括第一电极、发光层以及第二电极，像素电路包括第一连接部、驱动晶体管和阈值补偿晶体管，阈值补偿晶体管的第一极与驱动晶体管的第一极电连接，阈值补偿晶体管的第二极通过第一连接部与驱动晶体管的栅极电连接。子像素包括第一颜色子像素对，第一颜色子像素对包括第一像素块和第二像素块。第一像素块的第二电极在衬底基板上的正投影与第一连接部在衬底基板上的正投影的交叠面积与第二像素块的第二电极在衬底基板上的正投影与第一连接部在衬底基板上的正投影的交叠面积之比为0.8～1.2，由此可以降低两个第一颜色子像素中的驱动晶体管的栅极节点的负载差异。
