Abstract: PURPOSE:To detect a short-circuit defect by finding a rough range where a short-circuit defective thin film transistor (TR) is present from the resistance between one both ends of each scanning line and the resistance between one end of one of two scanning lines to be short-circuited and the other end of the other scanning line, and irradiating respective connection lines in this range with laser light in order. CONSTITUTION:The resistance between two scan bus lines SBn and SBn+1 to which the gate electrodes G and drain electrodes D of thin film TRs are connected is checked in order to detect a scan bus line to which the short-circuit TFT is connected. Then resistances RAA', RAB, and RAB' between terminals A and A', A-B, and A-B' led out of respective scan bus lines SBi and the place where the short defect is present is found roughly from the ratios of said values and RAB. Then while the resistance between the terminals A and B is measured, the connection lines 21, 22... in this range are irradiated with the laser light. Consequently, the short-circuit defect place of a matrix system opposite to gate connection can be specified.
