Abstract: A display device includes gate lines, data lines, first wires and second wires extending in the directions of the gate lines and data lines, and pixels having a first subpixel and a second subpixel each. The first subpixel has a first subpixel electrode and a first switching element, and the second subpixel has a second subpixel electrode and second and third switching elements. The control terminals of the three switching elements are connected to the same gate line, and the input terminals of the first and second switching elements are connected to the same data line. The first and second switching elements have output terminals connected to the first and second subpixel electrodes, respectively. The second switching element's output terminal connects to the third switching element, which has an output terminal connected to a second wire. The first wires and the second wires are connected in a pixel.
