<p>PURPOSE:To easily and surely check a defect by providing a signal line for check connected to the other end of a data signal line and checking a data signal line driving circuit and the data signal line based on the output from a video signal line. CONSTITUTION:Two signal lines 4 for data check to which data signal lines X are alternately connected are formed on the terminal side of data signal lines X from a data signal line driving circuit 2 to a picture element part 1, and data check signal input terminals S are provided in their end parts. Two signal lines 5 for scanning check to which scanning signal lines Y are alternately connected are formed on the terminal side of scanning signal lines Y from a scanning signal line driving circuit 3 to the picture element part 1, and scanning check signal output terminals G are provided in their end parts. In this case, check is performed through signal lines 4 for data check and signal lines 5 for scanning check in the terminals of data signal lines X and scanning signal lines Y, and these signal lines 4 and 5 are removed after the end of check.</p> |
