ABSTRACT:
A display apparatus includes a DSD for outputting a digital video signal and a wiring board. The wiring board includes a first wiring portion in which signal lines used to transmit the digital video signal output from the DSD are disposed, a signal generation circuit for generating drive voltage signals, and a second wiring portion in which signal lines used to transmit the drive voltage signals to a panel substrate are disposed. In the first wiring portion, a detection signal line used to transmit the drive voltage signals to the DSD is disposed. In the signal generation circuit, an output wiring portion including output lines used to transmit the drive voltage signals to the signal lines in the second wiring portion and a detection line having one end connected to the detection signal line and the other end connected to the output lines via switches are disposed.
