<P>PROBLEM TO BE SOLVED: To provide a driving method capable of improving the luminescence property of an organic EL device. <P>SOLUTION: The organic EL device includes a driving circuit and an electroluminescence portion ELP. The driving circuit includes a drive transistor TR<SB>D</SB>, a write transistor TR<SB>W</SB>, and a capacitor portion C<SB>1</SB>. By using the drive circuit, an auxiliary bootstrap processing for turning OFF the write transistor for one scanning time period in a state in which a higher voltage than a voltage obtained by subtracting a threshold voltage of the drive transistor from a first node initialization voltage is applied from the power source portion to one of the source/drain regions for a time period from the completion of the preprocessing to the start of the threshold voltage canceling processing to be executed right before execution of write processing to cause the potential at the second node to rise, thereby causing the potential at the first node held in the floating state to rise is executed at least once. <P>COPYRIGHT: (C)2009,JPO&INPIT |
