良、不良を判定で赦る。Next, the signal that has been detected by the upper P photoelectric conversion element 11, which shows the overall flow of the electric grid, is output to the above-mentioned monitor 16, and the desired pattern is displayed normally on the above-mentioned liquid crystal display device 13. The 0 judgment result that determines whether or not is displayed is
It is determined whether to output the signal to the control circuit 15 and proceed to the next display. Based on the signal from the control circuit 15, the drive circuit '14 outputs a signal for the next pattern to the liquid crystal display device 113. If the above-described process is repeated, it is possible to efficiently determine whether the liquid crystal display device 13 is good or bad in a short period of time.
