The elemental image points of color red, green blue forming a color image point are disposed in a triangle. An elemental image point is comprised of a thin film transistor connected to an electrode of a condenser, this electrode facing a second, colored electrode. The electrodes connected to a transistor are arrayed in lines, the other in columns. Each column of electrodes corresponding to a color successively red, green, blue. Three electrodes connected to three thin film transistors and forming a color image point are connected to one and the same address line conductor.
