<P>PROBLEM TO BE SOLVED: To effectively suppress deterioration of display quality resulting from an error included in current to be supplied to an electro-optic element. <P>SOLUTION: This pixel circuit has a capacitor C1, transistors T1, T2 which constitute a current mirror and an organic EL element OLED. At the time of setting of a first driving mode, the transistor T1 functions as a programming element for writing data according to data current Idata in the capacitor C1 and the transistor T2 functions as a driving element for generating driving current Ioled according to the data held in the capacitor C1. In addition, at the time setting of a second driving mode to be alternately switched to the first driving mode with predetermined cycle, the transistor T2 functions as the programming element and the transistor T1 functions as the driving element. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
