A display device includes: pixel transistors electrically connected to the respective source lines and the respective gate lines; a monitor transistor in which a lead-out wiring of a drain electrode is electrically connected to a first external terminal, a lead-out wiring of a gate electrode is electrically connected to a second external terminal, and a lead-out wiring of a source electrode is electrically connected to a third external terminal; a reference transistor in which a lead-out wiring of a drain electrode is electrically connected to a fourth external terminal, a lead-out wiring of a gate electrode is electrically connected to a fifth external terminal, and a lead-out wiring of a source electrode is electrically connected to a sixth external terminal; and a detector electrically connected to the third external terminal and the sixth external terminal to detect a shift amount of a threshold voltage of the monitor transistor.

Display device

A display device comprises: data lines extending in a first direction; gate lines extending in a second direction, and being divided into groups each of which has the gate lines adjacent in the first direction; selection signal supplying wirings each of which is provided in each group, and connected to each control electrode of the selector transistors corresponding to the group; gate voltage supplying wirings connected to the other conductive electrode of each of the selector transistors corresponding to the group; and wherein a gate driver supplies a second gate voltage having a voltage level lower than that of a first gate voltage to at least one of the gate voltage supplying wirings in each of the groups before supplying the first gate voltage in order to turn on a pixel transistor disposed in an intersection portion of the data line and the gate line.
