Abstract

A display device is provided in which each subpixel includes a driving TFT, an organic light-emitting diode, and at least one switching TFT for driving the subpixel. At least one of the driving TFT and the switching TFT is formed as a double-gate TFT having a first gate node and a second gate node, and each subpixel comprises a compensation circuit that senses a threshold voltage of the double-gate TFT and applies the same to the first gate node or the second gate node of the double-gate TFT.
