Abstract
Disclosed herein is a driving method of a display device. The display device includes display elements arranged in a form of a two-dimensional matrix and each have a driving circuit and a light emitting section. The driving circuit includes a driving transistor having a gate electrode and source/drain regions and a capacitance section, and a current flowing through the light emitting section via the source/drain regions of the driving transistor. The driving method includes the step of performing a first writing process, a second writing process, and then setting the gate electrode of the driving transistor in a floating state. A current corresponding to a value of a voltage retained in the capacitance section for retaining a voltage of the gate electrode of the driving transistor with respect to a source region of the driving transistor flows through the light emitting section, so that the light emitting section emits light.
