摘要： A display device includes a display panel on which gate lines, data lines and subpixels are disposed; a gate driving circuit which drives the gate lines; and a data driving circuit which drives the data lines. Each of the subpixels includes: a light emitting device; a second transistor which has a first node, a second node that is a gate node, and a third node electrically connected to the light emitting device, and drives the light emitting device; a first transistor electrically connected between the third node and the data line; a third transistor electrically connected between the first node and the second node; and a fourth transistor electrically connected between the third node and the light emitting device. The third transistor performs a turn-off operation later than the first transistor, so that a voltage applied to the third node is transmitted to the second node via the first node.
