Abstract: A display device includes: a pixel unit including pixels connected to first scan lines, second scan lines, and data lines; a scan driver for supplying a first scan signal to the pixels through the first scan lines at a first frequency and supplying a second scan signal to the pixels through the second scan lines at a second frequency different from the first frequency in a first mode; a first signal supply for supplying an inspection signal to the pixels through at least one of the data lines in response to the first scan signal in a first period of the first mode; and a second signal for supply supplying a bias signal to the pixels through the data lines in response to the first scan signal in a second period of the first mode.

Abstract: A display device includes a first electrode on a first conductive layer, a first insulating layer, a second electrode on a second conductive layer on the first insulating layer, a second insulating layer, a transistor active layer on a semiconductor layer on the second insulating layer, a gate insulating layer on the second insulating layer, and on a part of the active layer, a third electrode on a third conductive layer on the gate insulating layer, a third insulating layer on the second insulating layer, and covering the semiconductor layer, the gate insulating layer, and the third conductive layer, and a fourth electrode on the fourth conductive layer on the third insulating layer. The fourth electrode overlaps the first electrode and is directly connected to the first electrode through a first contact hole penetrating the first insulating layer, the second insulating layer, and the third insulating layer.
