<P>PROBLEM TO BE SOLVED: To improve effectiveness of an inspection result by enabling the inspection after installing a driving device. <P>SOLUTION: A data line driving circuit 200 comprises; n pieces of output terminals Tout, each of which is connected to a data line 103; a signal generation circuit 25 for generating data signals X1 to Xn according to a grayscale specified for each pixel; a detection wiring 30 for detecting current leak in each data line 103; and n pieces of switching elements 271, each of which is connected to the output terminal Tout. Each switching element 271 outputs the data signals X1 to Xn generated by the signal generation circuit 25 to each output terminal Tout when a driving mode is specified by a mode selection signal Smod, while all the output terminals Tout is made conductive to the detection wiring 30 when a detection mode is specified by the mode selection signal Smod. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
