Abstract: A driving circuit to drive a display apparatus includes first through third driving circuits to respectively receive first through third clock signals for respectively outputting a first gate signal with a gate-on voltage synchronized with rising edge timing of the corresponding clock signal in a first period in which data is supplied to the pixel in a frame period, a second gate signal with a gate-on voltage synchronized with rising edge timing of the corresponding clock signal in a second period for initializing a transistor of the pixel in the frame period, and a third gate signal with a gate-on voltage synchronized with rising edge timing of the corresponding clock signal in a third period for compensating for a threshold voltage of the transistor in the frame period. The rising edge timing of the second clock signal is different from the rising edge timing of the third clock signal.

Abstract: A gate driver includes an input circuit, a pull-up circuit, a pull-down circuit, a QB node control circuit and a Q node control circuit. The input circuit transmits an input signal to a Q node in response to a first clock signal. The pull-up circuit pulls up a gate output signal to a high voltage in response to a signal of a QF node. The pull-down circuit pulls down the gate output signal to a low voltage in response to a QB node. The QB node control circuit controls a signal of the QB node based on a QB control signal and a second clock signal. The Q node control circuit controls a signal of the Q node based on the QB node.

Abstract: A display apparatus includes a substrate, a wire having an inner edge including first and second portions, a first insulating layer covering a portion of the substrate, and a second insulating layer. The portion of the substrate covered by the first insulating layer is closer to a center of the substrate than the wire, the first insulating layer covers a part of the first portion of the wire and a part of the second portion of the wire, and a first end of the first insulating layer is disposed on the wire. The second insulating layer covers the first insulating layer and has a second end disposed on the wire. A distance between the first end and the second end covering the first portion of the wire is different from a distance between the first end and the second end covering the second portion of the wire.
