Abstract
A scan driver includes a stage, wherein the stage includes: a first output controller including a first pull-up transistor and a first pull-down transistor, wherein the first pull-up transistor has a gate connected to a first control node, and the first pull-down transistor has a gate connected to a second control node; a second output controller including a second pull-up transistor and a second pull-down transistor, wherein the second pull-up transistor has a gate connected to the first control node, and the second pull-down transistor has a gate connected to the second control node; and a stabilizer configured to maintain the first control node at an off-voltage level based on the second control node being at an on-voltage level.
