Abstract:
1. A drive method of a display device having: an array substrate; an opposing substrate facing the array substrate; and an electro-optic substance held between the array substrate and the opposing substrate, the array substrate being provided with: a plurality of gate wirings and a plurality of source wirings intersecting each other; a pixel electrode disposed in a region defined by two adjacent gate wirings and two adjacent source wirings; a switching element for switching a voltage applied to the pixel electrode from the source wiring based on a signal voltage supplied from the gate wiring; and a common wiring formed between the two adjacent gate wirings; and an opposing electrode being electrically connected to the common wiring and generating an electric field for driving the electro-optic substance between the opposing electrode and the pixel electrode whereto a voltage is applied, the pixel electrode and the opposing electrode being made of the materials having different transmittances, said method comprising the step of adding a prescribed brightness compensation voltage to the voltage applied to the pixel electrode.
