Abstract
PURPOSE:To easily and accurately perform inspection by providing an inspection panel equipped with a detection electrode matrix of structure similar to that of the picture element matrix of the liquid crystal display device and detecting characteristics of individual switching elements of a substrate to be inspected which is arranged opposite. CONSTITUTION:The inspection panel 1 has detection electrodes 4 arrayed in matrix structure having pitch similar to that of picture elements 3 of the matrix stricture of a liquid crystal display device substrate 2, and an insulator layer 8 is formed thereupon. An electrode 4 is provided with a scanning electrode 6 and a signal electrode 7 at an intersection of switching elements 5 made of TFTs. A scanning electrode driving circuit 10 applies a voltage to the electrode 6 at the time of the inspection and a detection signal obtained through the switching element 5 and electrode 4 is stored in a storage device 14 through a detecting circuit 13 and further inputted to a computer 15 to accurately inspect the characteristics of the object switching element.
