Abstract: A display apparatus includes a first transistor, a first data line, a second data line, a driving voltage line, and a first insulating layer. The first transistor includes a first semiconductor layer and a first gate electrode. The first semiconductor layer includes a source region and a drain region. The first data line is disposed at a left side of the first transistor, and the second data line is disposed at a right side of the first transistor. The driving voltage line at least partially overlaps the first data line and the second data line. The first insulating layer is disposed between the first data line and the driving voltage line and between the second data line and the driving voltage line.

Abstract: A driver includes a stage that includes a first controller, a second controller, and a first output unit. The first controller controls a voltage level of a first node. The second controller controls voltage levels of a second node and a third node to be equal to the voltage level of a first node or an opposite voltage level of the voltage level of the first node, and controls a voltage level of a fifth node to be equal to the opposite voltage level of the voltage level of the first node. The first output unit may output a gate control signal, which has a first voltage when the second node and the third node is in an on-voltage level state, and has a second voltage when the fifth node is in an on-voltage level state.
