发明名称 LIGHT EMITTING APPARATUS, DRIVING CIRCUIT OF LIGHT EMITTING ELEMENT, AND DRIVING METHOD
摘要 A light emitting apparatus includes a light emitting element, a driving circuit which has a driving transistor having a gate, a drain, and a source, and a capacitor having one end connected to the gate, a power line, and first and second voltage lines, and, in a period in which the gate and the drain are short-circuited and the drain and the light emitting element are blocked, the source is connected to the first voltage line and the other end of the capacitor is connected to the second voltage line to hold a voltage in the capacitor, and, in a period in which the gate and the drain are disconnected and the drain and the light emitting element are connected, the source is connected to the power line, and the other end of the capacitor is connected to the source to supply a current to the light emitting element.
