Abstract:
1. A light emitting device comprising: a light emitting element; a first transistor, wherein one of a source and a drain of the first transistor is connected to the light emitting element; a second transistor, wherein one of a source and a drain of the second transistor is directly connected to the other of the source and the drain of the first transistor; a third transistor, wherein one of a source and a drain of the third transistor is directly connected to the other of the source and the drain of the second transistor; a power supply line directly connected to the other of the source and the drain of the third transistor; a first scanning line connected to a gate of the first transistor and a gate of the third transistor; a capacitor comprising a first electrode and a second electrode, wherein the first electrode is electrically connected to a gate of the second transistor; a fourth transistor, wherein one of a source and a drain of the fourth transistor is connected to the first electrode of the capacitor; a second scanning line connected to a gate of the fourth transistor; and a fifth transistor, wherein one of a source and a drain of the fifth transistor is connected to the other of the source and the drain of the first transistor.
