Claim 17:
18. A display device comprising:
a driving voltage line;
a light emitting element including an anode and a cathode;
a capacitor;
a transistor including a gate electrode connected to the capacitor, an oxide semiconductor layer including a channel region, a first electrode connected to the anode of the light emitting element, and a second electrode connected to the driving voltage line; and
a lower layer electrically connected to the first electrode and including an overlapped region where a body portion and the channel region of the transistor overlap each other in a plan view and a plurality of protrusions protruding from the overlapped region,
wherein the plurality of protrusions include a plurality of first protrusions extending in a first direction and a plurality of second protrusions extending in a direction opposite to the first direction.
