1. A display device comprising:
a transistor with a semiconductor layer and a gate electrode;
a pixel including the transistor and a display area emitting light to an outside of the pixel;
a first transparent conductive layer overlapping more than half of the gate electrode in a direction of a gate length in a plan view and being in contact with the semiconductor layer in a first contact area not overlapping the gate electrode; and
a second transparent conductive layer overlapping the gate electrode in a plan view and being connected to the first transparent conductive layer in a second contact area overlapping the gate electrode,
wherein
a first part of the second transparent conductive layer overlaps the display area in a plan view,
the first transparent conductive layer is in contact with the second transparent conductive layer in a contact hole,
the contact hole is filled with a spacer, and
a part of the spacer is located outside the contact hole.
