Disclosed are a shift register and a display device using the shift register to prevent current leakage and deterioration of the oxide transistor due to light, thereby enhancing output stability. The shift register includes a plurality of stages, each stage comprising: a transmission line unit including a plurality of clock lines for supplying a plurality of clock signals and a plurality of power supply lines for supplying a plurality of power supply voltages; a transistor unit, The transistor unit including a plurality of transistors; and a light blocking layer overlapping at least one transistor of the transistor unit to block light. The transistor unit of each stage includes an output unit including a pull-up transistor for outputting any one of the plurality of clock signals as the scan signal in response to control of the first node and a first node controller. The first node controller includes a plurality of transistors for controlling charging and discharging of the first node. 公开了种移位寄存器及使用该移位寄存器的显示装置
