Abstract:
1. A method of driving a pixel circuit, said pixel circuit including a first transistor connected between a power source and a light emission portion, a second transistor connected to a date line, and a capacitor connected between a gate electrode and a current electrode of the first transistor, the method comprising, within a given frame period: turning ON the second transistor at a first timing, the first timing occurring while a first video signal voltage is applied to the data line; subsequent to the first timing, initializing a potential at the capacitor by applying an initialization voltage to the data line; and supplying a second video signal voltage from the data line to the capacitor through the second transistor, wherein the gate electrode of the first transistor is connected to the capacitor via a first node, and the capacitor and the light emission portion are connected to the current electrode of the first transistor via a second node, the method further comprising, while performing the aforementioned initializing a potential at the capacitor, applying a second initializing voltage, lower than driving voltage for driving light emission of the light emission portion, to the second node.
