DISPLAY DEVICE AND METHOD FOR DRIVING DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To correctly correct threshold voltage even when not regulating a period correcting the threshold voltage of a transistor driving a light emitting element.

SOLUTION: The display device corrects irregularity of a transistor TR2 and sets gradation by setting a signal level of a signal line SIG after setting the threshold voltage of the transistor TR2 in the capacitor Cs2 for holding a signal level provided between gate sources of the transistor TR2 to the transistor TR2 driving by current the light emitting element 12. It discharges accumulation charge of the transistor TR2 through the light emitting element 12, and is held at the threshold voltage of the transistor TR2 by supplying lowering of voltage between the gate sources by lowering of terminal voltage due to discharge of the accumulation charge of the light emitting element 12 after the voltage between the gate sources lowers down to the threshold voltage of the transistor TR2.
