An inspecting device for a display panel module is provided to accurately detect an error state of the short or open circuit of signal lines on a panel substrate by a voltage level generated in the signal lines by a voltage display unit. An inspecting device(100) for a display panel module(200) includes a driving signal generating unit(110), a printed circuit board(120), mounting units(130,132,134), and a voltage display unit(140). The driving signal generating unit outputs a plurality of driving signals to signal lines wired in the display panel module. The printed circuit board receives the driving signals from the driving signal generating unit. The mounting units are electrically connected to the printed circuit board. The mounting units transmit the driving signals inputted through the printed circuit board to external apparatuses through the signal lines of the display panel module held in upper parts of the mounting units. The voltage display unit is electrically connected to the signal lines of the display panel module. The voltage display unit displays voltage levels of the driving signals. |
