A display includes an electric current controlled light-emitting device that emits light with a luminance depending on an electric current flowing therethrough. The display also includes a transistor that has a gate electrode, a source electrode, and a drain electrode, and controls the electric current based on a data voltage between one of the source and drain electrodes and the gate electrode; and a controller that controls a gate-to-source voltage and a gate-to-drain voltage of the transistor based on a change in the luminance of the electric current controlled light-emitting device while maintaining the transistor element in a saturation region.
