Abstract

Disclosed is a shift register which is an embedded shift register using an oxide transistor is capable of improving output performance, operation range and output stability, and a display device using the same. In the shift register, each stage includes at least two light shielding layers individually overlapped with the transistors of the stage by dividing the transistors into at least two regions, and a connection transistor selectively applying a voltage to a first shielding layer overlapped with the pull-up transistor of the two light shielding layers to allow the first light shielding layer to float.
