Abstract: An image display with high brightness where a long time can be secured for light emission of self-luminous elements can be implemented using only line memories. The period for the writing in of a display voltage (period for writing in of data) continues for a number of lines (three lines), and the reset pulse becomes of a “high” state. Subsequently, operation for three lines is carried out collectively during a triangular wave period (period for writing in of a triangular wave voltage), and only the light emission controlling pulse becomes of a “high” state. During the period for the writing in of a triangular wave voltage, the writing in of a triangular wave voltage from the second time onward is rewriting of a triangular wave voltage, and thus, the period for rewriting the display voltage (dotted line portion) becomes unnecessary, and a longer period for light emission, where the light emission controlling pulse becomes of a “high” state, can be secured.

A data line driving circuit 14 is provided with a triangular wave generating circuit 71 for generating a number of types of triangular waves having different phases and waveforms, and a gradation voltage-triangular wave switching circuit 75 for selecting and switching one of the number of types of triangular waves generated by the triangular wave generating circuit 71 for each signal line. One horizontal period is divided into a signal write-in period and a triangular wave period, so that the signal voltage and the triangular wave are outputted during the signal write-in period and the triangular wave period, respectively. Different triangular waves are selected and outputted for each signal line, so that the location of the shift in the outline in a moving image changes for each column.
