Abstract

显示面板及显示装置，涉及显示技术领域。显示面板通过在基底(10)上设置多个子像素(20)，每个子像素(20)包括补偿晶体管(T1)、驱动晶体管(T2)、存储电容(Cst)和第一初始化信号线(252)，补偿晶体管(T1)的第一有源图案(211)包括依次连接的第一有源部(2111)、第二有源部(2112)和第三有源部(2113)，第二有源部(2112)沿第一方向延伸，且第一有源部(2111)和第三有源部(2113)的延伸方向均与第一方向相交；第一初始化信号线(252)沿第一方向延伸，且第一初始化信号线(252)在基底(10)上的正投影与第二有源部(2112)在基底(10)上的正投影存在重叠区域，直接通过第一初始化信号线(252)与第一有源图案(211)交叠形成耦合电容。
