1. A display apparatus including a plurality of pixels, wherein each of the plurality of pixels includes:
a light-emitting diode;
a first transistor electrically connected to a driving voltage line and the light-emitting diode;
a second transistor electrically connected to the first transistor and the light-emitting diode;
a third transistor electrically connected to the second transistor and a first initialization voltage line; and
a fourth transistor electrically connected to the light-emitting diode and a second initialization voltage line, and wherein:
during a frame, each of the plurality of pixels operates in a first scan period and a second scan period, wherein the first scan period includes a write-period in which a data signal is supplied and a first emission period in which each of the plurality of pixels is configured to emit light at a brightness corresponding to the data signal, wherein the second scan period includes a second emission period in which the data signal is maintained and each of the plurality of pixels is configured to emit light at a brightness corresponding to the data signal,
during the second scan period, the third transistor is supplied with a first initialization voltage from the first initialization voltage line, and the fourth transistor is supplied with a second initialization voltage from the second initialization voltage line, and
during the second scan period, a magnitude of the first initialization voltage and a magnitude of the second initialization voltage are equal to a first voltage.
