The present invention comprises pixels each configured by a switching element and a light-emitting element, and a plurality of source signal lines for one pixel column. An input terminal of the switching element is connected to any one of the plurality of source signal lines and an output terminal of the switching element is connected to the light-emitting element so as to enable a light emission when the switching element is turned ON. Pixels in plurality of rows emit light simultaneously, so that a longer light emission time can be realized. It can make the lifetime of an element longer and the power consumption lower.
