Patent ID: 8542164

Claim:
A display device comprising: a wiring; a light emitting element including a first electrode, an electroluminescent layer over the first electrode and a second electrode over the electroluminescent layer wherein the second electrode of the light emitting element is electrically connected to the wiring; a capacitor including a first electrode and a second electrode; a first transistor wherein one of a source and a drain of the first transistor is electrically connected to the first electrode of the light emitting element; a second transistor wherein one of a source and a drain of the second transistor is electrically connected to the wiring and the other of the source and the drain of the second transistor is electrically connected to the first electrode of the capacitor; a third transistor wherein a gate of the third transistor is electrically connected to the first electrode of the capacitor and one of a source and a drain of the third transistor is electrically connected to the other of the source and the drain of the first transistor; a fourth transistor wherein a gate of the fourth transistor is electrically connected to a gate of the first transistor and one of a source and a drain of the fourth transistor is electrically connected to the other of the source and the drain of the third transistor; a fifth transistor wherein one of a source and a drain of the fifth transistor is electrically connected to the other of the source and the drain of the first transistor and the other of the source and the drain of the fifth transistor is electrically connected to the other of the source and the drain of the second transistor; and a sixth transistor wherein one of a source and a drain of the sixth transistor is electrically connected to the other of the source and the drain of the third transistor.
