Abstract:
1. A method of driving a light emitting device including a first power supply line, a second power supply line, a first transistor that is P-channel type, a driving transistor that controls a driving current flowing between the first power supply line and the first transistor and that is P-channel type, a light emitting element having a first electrode coupled to the first transistor and a second electrode coupled to the second power supply line, a capacitor having a first end coupled to a first gate of the driving transistor and a second end, and a second transistor coupled between the second end of the capacitor and a data line, the method comprising: setting a first gate potential of the driving transistor through the second transistor and the data line by turning the second transistor on and turning the first transistor off during a writing period, supplying the driving current through the first transistor to the light emitting element for a light emitting period during which the light emitting element is allowed to emit light, when let −V
