Abstract: A display apparatus includes a display panel, a gate driver, a data driver and an emission driver. The display panel includes a pixel. The gate driver is configured to output a gate signal to the pixel. The data driver is configured to output a data voltage to the pixel. The emission driver is configured to output an emission signal to the pixel. The pixel includes a light emitting element, a driving switching element configured to apply a driving current to the light emitting element and a bias switching element configured to apply a bias voltage to the driving switching element. The display apparatus increases a level of the bias voltage when a duration of a light emission time of the pixel is increased.
