There is disclosed a display device comprising a display panel having plural a plurality of pixel elements, plural driver circuit elements for receiving a serially input image signal, converting the signal into a parallel form, and then sending the converted signal to the display panel, and a printed-wiring board. This printed-wiring board has a plurality of signal output terminals for delivering the serial image signal and control signals to the driver circuit elements. The printed-wiring board further includes dummy output terminals close to the signal output terminals. One of the dummy terminals is electrically connected with one signal output terminal within the printed-wiring board. Another dummy terminal is electrically connected with another signal output terminal within the printed-wiring board. Thus, an inspection can be performed easily. Furthermore, the cause of a defect in the displayed image can be readily identified. Hence, the time taken to repair the device can be shortened.
