参阅图4，图4是本发明液晶显示面板第二实施例的像素单元的结构示意图。在本实施例中，像素电极23的长边优选与扫描线20平行设置，薄膜晶体管22的漏极d1具有延长部28以作为扫描线20的修复线，其中，延长部28沿着平行于扫描线20的方向延伸，且延长部28远离薄膜晶体管22的一端与扫描线20部分重叠。扫描线20在邻近延长部28远离薄膜晶体管的一端处对应设有凸起部27，凸起部27朝向延长部28延伸且和延长部28的末端部分重叠。
在本实施例中，凸起部27优选设置为与扫描线20垂直相接，在其他实施例中，凸起部27也可以设置为与扫描线不垂直相接。
参阅图5，图5是本发明液晶显示面板第一实施例中扫描线发生断线后的修补结构示意图。当扫描线20发生断线时，将位于薄膜晶体管22的漏极d1和栅极g1的重叠区域处的A点打通孔并且利用激光焊接实现漏极d1与栅极g1之间的电连接，同时将延长部26和扫描线20的重叠处B点打通孔并利用激光焊接技术处理以实现延长部26和扫描线20的电连接，由于栅极g1与扫描线20为电连接，则上述方式可实现扫描线20两端的电连接，通过上述A、B两点的电连接处理，从A点到B点的修复线充当扫描线，可以起到修复扫描线的效果。
参阅图6，图6是本发明液晶显示面板第二实施例中扫描线发生断线后的修补结构示意图。当扫描线20发生断线时，将薄膜晶体管22的漏极d1和栅极g1的重叠区域处C点打通孔并且利用激光焊接实现漏极d1与栅极g1之间的电连接，同时将延长部28与扫描线20的凸起部27的重叠处D点打通孔并利用激光焊接以实现延长部28和扫描线20的凸起部27之间电连接，由于栅极g1与扫描线20为电连接，则上述方式可实现扫描线20两端的电连接，通过上述C、D两点的电连接处理，从C点到D点的修复线充当扫描线，同样可以起到修复扫描线的效果。
此外，本发明还提供了一种液晶显示装置。参阅图7，图7为本发明的液晶显示装置的结构示意图。液晶显示装置30包括液晶显示面板31以及背光模组32，液晶显示面板31为上述任一种实施方式所述的液晶显示面板。
区别于现有技术的情况，本发明通过利用薄膜晶体管的漏极的延长部充当扫描线断线时的修补线，在扫描线断线时用激光焊接技术将扫描线两端重新电连接，从而能够将扫描线断线的不良品修补成良品，提高生产良率从而节约生产成本。
以上所述仅为本发明的实施方式，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
