<P>PROBLEM TO BE SOLVED: To improve display quality by reducing degradation in the display quality due to the variations in the luminance of light-emitting elements, which is caused by the variations in the voltage due to the wiring resistance of current supply lines. <P>SOLUTION: In a voltage program period, a terminal serving as a source of a transistor for driving an EL element is electrically connected to a first wiring to which a first potential is supplied; in a light-emitting period, the terminal serving as the source of the driving transistor is electrically connected to a second wiring to which a second potential is supplied; and consequently, voltage between a gate terminal and the source terminal of the driving transistor can be held without being adversely affected by the variation in voltage because of the wiring resistance of the current supply lines. <P>COPYRIGHT: (C)2010,JPO&INPIT |
