A self light emission display device which substantially enables dual scan drive by one data driver comprises a plurality of scan lines K1, K2, . . . which are arranged in a horizontal direction, a plurality of data lines A1, A2, . . . which intersect these scan lines and are arranged in a vertical direction, and a plurality of light emitting elements Ra11, Rb11, . . . arranged on intersecting areas of the scan lines and the data lines. Cathode terminals of the light emitting elements whose anode terminals are connected respectively to the two adjacent data lines A1, A2 are connected to different scan lines one by one. Any two of the scan lines are selected for scanning simultaneously. Thus, since light emission duty of each EL element can also be approximately doubled, instantaneous light emission intensity of each EL element can be set low, and stress on the EL elements can be reduced. Further, since respective data lines can be drawn from one side end portion of the display panel, dual scan drive becomes substantially possible by one data driver.
