A display apparatus includes a display panel, a driving controller, a gate driver, an emission driver and a data driver. The display panel includes a pixel including a driving switching element and a light emitting element. The driving controller is configured to determine a driving frequency varied according to input image data or a driving mode. The gate driver is configured to output a gate signal and a bias control signal to the pixel. The emission driver is configured to output an emission signal to the pixel. The data driver is configured to output a data voltage to the pixel. The bias control signal to apply a bias voltage to the driving switching element has a first width in a writing frame and a second width different from the first width in a holding frame.
