Patent ID: 8362489

Claim:
A light-emitting device comprising: a data line; a scan line; a pixel electrode; a counter electrode; a light-emitting element disposed between the pixel electrode and the counter electrode; and a first transistor having a conduction state controlled by data signals supplied through the data line, the first transistor controlling a current level of a current that flows through the light emitting element, the light-emitting device being configured such that: the data signals include a first data signal that sets a gate voltage of a first gate of the first transistor to a first gate voltage, the first gate voltage turning on the first transistor; and the data signals include a second data signal that sets the gate voltage of the first gate of the first transistor to a second gate voltage, the second gate voltage turning on the first transistor, and the second gate voltage being greater than the first gate voltage, wherein the light-emitting element does not emit a light during a first period in which the first gate voltage is applied to the first gate, and the light-emitting element emits a light during a second period in which the second gate voltage is applied to the first gate.
