Abstract
A main object of the present invention is to make it possible to supply current to electric field light emitting elements without decreasing the aperture ratio of pixels. In order to achieve the object, the present invention provides an image displaying device wherein: current driven typed light emitting elements and transistors for current driving are formed on a same substrate; comprising a plurality of display cells having such a structure that the current driven typed light emitting elements and transistors for current driving are connected in between a power supply line and a ground line; the transistors for current driving are selectively driven to conduct display; and a power supply electrode column for supplying currents to each display cell is formed on a power supply common electrode that is formed on a surface of a facing substrate parallel to the substrate.
