Abstract: A display apparatus includes a substrate which includes a first pixel area and a second pixel area. A third pixel area is spaced apart from the second pixel area. A notch peripheral area is adjacent to the first, second and third pixel areas. A plurality of pixels are provided in the first, second and third pixel areas. A first scan line is disposed on the substrate. The first scan line includes a first portion disposed in the second pixel area, a second portion disposed in the third pixel area, and a third portion which connects the first portion to the second portion. The third portion is disposed in the notch peripheral area. A second scan line is disposed on the substrate in the first pixel area. A surface area of the first scan line is from about 90% to about 110% of a surface area of the second scan line.

Abstract: A gate driver comprises a plurality of stages. Each of the stages includes a writing selection circuit configured to apply a writing selection signal to a first inversion control node based on the writing selection signal in a writing period, a holding selection circuit configured to apply a holding selection signal to a second inversion control node based on the holding selection signal in a holding period, and a gate output circuit configured to output a first low gate voltage as a low gate voltage in response to a voltage of the first inversion control node in the writing period, and output a second low gate voltage that is different from the first low gate voltage as the low gate voltage in response to a voltage of the second inversion control node in the holding period.

Abstract: An emission driver includes a plurality of stages. A stage of the plurality of stages receives a start signal, a first clock signal, a second clock signal, a protection signal, a first gate power voltage and a second gate power voltage and outputs an emission signal. The stage of the plurality of stages includes a pull-up switching element connected between a first gate power voltage terminal which receives the first gate power voltage and an emission signal output terminal which outputs the emission signal, a pull-down switching element connected between a second gate power voltage terminal which receives the second gate power voltage and the emission signal output terminal and a protection switching element which applies the first gate power voltage to a control electrode of the pull-down switching element in response to the protection signal.
