Zusammenfassung:The present disclosure relates to a gate driver and an organic light-emitting display device including same. A gate driver according to an embodiment of the present disclosure includes a plurality ofstages. Each of the stages includes: a first pull-up transistor configured to output a carry clock to a first output terminal as a carry signal while a Q node is bootstrapped to a voltage higher thana gate on voltage; a second pull-up transistor configured to output a scan clock to a second output terminal as a scan signal while the Q node is bootstrapped; and holding transistors configured to operate based on a voltage of a QB node, which QB node is charged and discharged in a manner reverse to that of the Q node. The holding transistors are connected to the second output terminal and the Qnode, and the holding transistors are electrically isolated from the first output terminal. 本公开内容涉及栅极驱动器和包括该栅极驱动器的有机发光显示装置。根据本公开内容的实施方式的栅极驱动器包括多个级。每个级包括:第一上拉晶体管,其被配置成在Q节点被自举至高于栅极导通电压的电压时将进位时钟作为进位信号输出至第一输出端子;第二上拉晶体管,其被配置成在Q节点被自举
