Patent ID: 8610117

Claim:
A display panel comprising: a light emitting element over a substrate; a capacitor over the substrate; a first transistor over the substrate; a second transistor over the substrate; a third transistor over the substrate; a fourth transistor over the substrate; a wiring over the substrate; and a seal member over the substrate, wherein one of a source and a drain of the first transistor is electrically connected to the light emitting element, wherein the other of the source and the drain of the first transistor is directly connected to one of a source and a drain of the second transistor, wherein the other of the source and the drain of the second transistor is directly connected to a first line, wherein one of a source and a drain of the third transistor is directly connected to a gate of the first transistor, wherein the other of the source and the drain of the third transistor is electrically connected to a second line, wherein a gate of the third transistor is directly connected to a third line, wherein one of a source and a drain of the fourth transistor is directly connected to the other of the source and the drain of the first transistor, wherein a gate of the fourth transistor is directly connected to a fourth line, wherein a first electrode of the capacitor is directly connected to the gate of the first transistor, wherein a second electrode of the capacitor is directly connected to the first line, wherein the wiring is electrically connected to the first line, wherein the wiring is in contact with the seal member, and wherein the wiring is electrically connectable to an FPC.
