The present invention relates to a display device. The display device includes a display panel having gate lines and data lines, a driving chip mounted on the display panel, and a flexible printed circuit film (FPC) attached to the display panel. The display panel includes a plurality of first to third pads, a first switching element, a second switching element, a first test pad, and a second test pad. The plurality of first to third pads are sequentially disposed and electrically connected with each other. The first switching element is interposed between the first pad and the second pad. The second switching element is connected to the third pad. The first test pad is commonly connected to control terminals of the first and second switching elements. The second test pad is connected to an input terminal of the second switching element. According to the present invention, processing time and production yield can be increased by improving the detection performance in a visual inspection test process.
