1. A display device comprising:
a substrate; and
pixels on the substrate, each of the pixels comprising:
a transistor including a gate electrode and a semiconductor layer having a channel region, the gate electrode overlapping the channel region in a plan view;
a first transparent electrode directly in contact with the semiconductor layer;
a first insulating layer located on the first transparent electrode and having an opening that exposes the first transparent electrode and overlaps the channel region in the plan view;
a second transparent electrode located on the first insulating layer and electrically connected to the first transparent electrode via the opening, the first insulating layer being located between the first transparent electrode and the second transparent electrode;
a second insulating layer on the second transparent electrode, a part of the second insulating layer being located in the opening;
a third transparent electrode located on the second insulating layer, a part of the third insulating layer being located in the opening, the second insulating layer being located between the second transparent electrode and the third transparent electrode; and
a metal layer located in the opening and between the second insulating layer and the third transparent electrode, the metal layer directly in contact with neither the first transparent electrode nor the second transparent electrode.
