Abstract: <P>PROBLEM TO BE SOLVED: To compensate a threshold voltage of a driving transistor with respect to a technique for controlling behaviors of electro-optical elements.  <P>SOLUTION: A driving transistor M1 generates a driving current Iel corresponding to a potential of a gate thereof. A light emitting element 11 emits light with luminance corresponding to the driving current Iel. A threshold voltage Vth is stored in a first capacitive element C1, and a data voltage is held in a second capacitive element C2. A potential of a connection point Z is fixed to a reference potential Vref during a write period when a data potential VD[j] is written, and a compensation period when the threshold voltage is compensated. Therefore, it is possible that the data voltage is written to the second capacitive element C2 simultaneously at the time of writing the threshold voltage to the first capacitive element C1. During a light emission period, the threshold voltage compensated driving current Iel is supplied to the light emitting element 11 because the first capacitive element C1 and the second capacitive element C2 are connected in series between a gate and a source of the driving transistor M1.  <P>COPYRIGHT: (C)2007,JPO&INPIT
