1. A display device, comprising:
a substrate including a display area including a plurality of pixels, and a peripheral area at least partially surrounding the display area;
a first transistor disposed in each of the plurality of pixels, the first transistor including a semiconductor layer including a channel area;
an overlap layer disposed between the channel area of the first transistor and the substrate in a sectional view, the overlap layer overlapping the channel area of the first transistor in a plan view; and
a driving voltage line disposed over the first transistor in the sectional view and transmitting a driving voltage,
wherein the overlap layer is supplied with the driving voltage through a contact hole which is for electrical connection between the overlap layer and the driving voltage line, and
wherein the contact hole is not disposed in an area of the pixel.
