Display device and method of driving the same

摘要

A circuit for driving an organic light emitting element by alternating current in an active matrix organic light emitting display is provided. A circuit of a pixel provided with a switching TFT and a current controlling TFT further is provided with an element that has a rectifying characteristic. The switching TFT charges a capacitor in accordance with a data signal and the current controlling TFT controls light emission of an organic light emitting element in accordance with voltage supplied from the capacitor. Reverse bias is readily applied to the organic light emitting element by applying voltage to the element that has a rectifying characteristic in the forward direction from an alternating current source.
