Abstract
Disclosed is a shift register which prevents current leakage and degradation of an oxide transistor due to light to improve output stability, and a display device using the same. The shift register includes a plurality of stages, and each stage includes a transmission line unit including a plurality of clock lines to supply a plurality of clock signals and a plurality of power lines to supply a plurality of voltages, a transistor unit including a plurality of transistors, and a light-shielding layer overlapping at least one transistor of the transistor unit so as to block light.
