For an inspection of a display device which incorporates a driver circuit around pixels, a start pulse and a clock pulse are required to be inputted as inspection signals. The more complex the driver circuit is, the more complexity the start pulse and the clock pulse tend to have, which will increase the manufacturing cost of inspection signals. In addition, since a clock generator is required, cost of an inspection device is increased. Furthermore, it will lead to a longer inspection time. By setting all the power supplies for the driver circuit at a desired potential, a desired potential is outputted regardless of an input signal.
