<P>PROBLEM TO BE SOLVED: To control current flowing in a light emitting element without being influenced by the property of a thin-film transistor. <P>SOLUTION: In a writing period, no current flows in the light emitting element, and the drain current of a first transistor flows into the light emitting element during a writing period. Accordingly, the capacitor of the light emitting element does not influence the length of period which starts with change of the gate voltage and which ends with stabilization of the gate voltage value. Therefore, compared to pixels of prior art, the pixel of the present invention is quicker in stabilizing the voltage converted from a supplied current and shorter in current writing time, and can prevent after image from being recognized in animation display. <P>COPYRIGHT: (C)2009,JPO&INPIT |
