1. A display apparatus comprising:
a display panel comprising a pixel;
a gate driver which provides a gate signal to the pixel;
a data driver which provides a data voltage to the pixel; and
an emission driver which provides an emission signal to the pixel,
wherein the pixel comprises:
a light emitting element;
a driving switching element which applies a driving current to the light emitting element;
a storage capacitor connected to a control electrode of the driving switching element; and
a bias capacitor including a first electrode connected to the storage capacitor and a second electrode which receives a bias gate signal, and
wherein a waveform of the bias gate signal varies based on an off ratio representing a ratio of an off period of the emission signal in a frame period.
