Patent ID: 7298163

Claim:
A TFT array inspection device for inspecting a TFT array substrate having a TFT array arranged in a matrix pattern and driving electrode terminals, comprising: array inspection electrodes disposed on the TFT array substrate and connected to the driving electrode terminals, said array inspection electrodes being arranged on said TFT array substrate commonly with other TFT array substrates regardless of layouts thereof, at least one probe frame electrically connected to the array inspection electrodes of the TFT array substrate, probe pins disposed on the at least one probe frame for contacting the array inspection electrodes, said probe pins being arranged to correspond to an arrangement of the array inspection electrodes of the TFT array substrate, and connecting means detachably attached to the at least one probe frame for connecting between the at least one probe frame and an external device, said connecting means having switching means for switching connections between the probe pins and the external device, said switching means including a connection switching connector having a wiring for connecting between the probe pins and the external device according to the layout of the TFT array substrate, wherein a plurality of connecting means different from each other, each having a wiring corresponding to the layout of the TFT array substrate to be inspected, is prepared, and the at least one probe frame is used commonly for the TFT array substrates with different layouts by selecting and changing to one of the plurality of connecting means.
