PROBLEM TO BE SOLVED: To provide a display device, capable of detecting a drive voltage signal. SOLUTION: The display device is provided with: a DSD 2 which outputs digital image signal; and a wiring substrate 3R including a first wiring part 32 in which signal wiring 32_1-32_10 for transmitting the digital image signal output by the DSD 2 is arranged, a signal generation circuit 31R which generates drive voltage signal, and a second wiring part 33 in which signal wiring 33_1-33_320 for transferring the drive voltage signal to a panel substrate 4R is arranged. Detecting lines 31-13 for transferring the drive voltage signal to the DSD 2 are disposed in the first wiring part 32, and output lines Y_1-Y_320 for outputting the drive voltage signal to each signal wiring 33_1-33_320 and a detection line Ys having one-side end connected to the detecting wiring 32_12 and the other end connected to optional output lines Y_1-Y_32 through opening and closing switches SW1_1-SW1_32 are provided in the signal generation circuit 31R.
