An inspection apparatus for inspecting wires of an object in which a plurality of x-axis and y-axis wires are arranged perpendicular to each other, each x-axis and y-axis wire having a display wire and tab wire, respectively. The apparatus includes a power supply device supplying an AC signal to the wire as an inspection object; a connecting device being in conductive contact with the tab wire to transmit the AC signal, a first detecting device disposed in a non-contact manner at one end of the display wire and conductively connected to one end of the power supply device, a second detecting device disposed in the non-contact manner and opposed to the display wire and conductively connected to the one end of the power supply device, and a determining device determining quality of the wire on the basis of results of the first and second detecting devices.
