<p>PURPOSE:To materialize the reduction of manhour in inspection and the price down of an inspection device, and improve productivity, concerning the method of inspecting the a matrix type liquid crystal display board which has X-Y cross over. CONSTITUTION:The method of inspecting the a matrix type liquid crystal display board which has X-Y cross over is as follows: inspection heads 32a and 32b consisting of conductive materials with lengths covering arrangement areas are pressed to each of the arrangement areas at least on each side of driving electrodes 11a' and 11b' exposed in line in X and Y directions near time peripheral piece of the display board and are brought into contact with each driving electrode en-block. The voltage below the breakdown strength voltage of a switching element positioned near the cross point is applied between the inspection head 32a corresponding to the driving electrode 11a' in Y direction and the inspection head 32b corresponding to the driving electrode 11b' in Y direction, and then the inspection heads 32a and 32b are removed.</p> |
