    • An object of the invention is to shorten the inspection time of wiring board. A high frequency signal is applied to source signal wiring of a substrate member 12 put on a table 13 from signal feeding means 17 through terminals of a frame 14. A signal of which voltage absolute value is greater than the voltage amplitude of the high frequency signal and voltage polarity is positive is applied to a scanning wiring of the substrate member 12. An infrared image of the substrate member 12 with signal applied is taken by image pickup means 15. In image processing means 16, from the image data fed from the image pickup means 15, an infrared image changing in contrast depending on the emission of infrared rays is formed, and the infrared image is divided into plural regions equal in the size of wiring pattern. In control means 18, the image of each divided region is compared with images of plural adjacent regions, and difference is detected. When a difference is detected, it is judged there is a defect in that region.
    • 本发明的目的是缩短布线板的检查时间。 从信号馈送装置17通过帧14的端子将高频信号施加到放置在台13上的基板部件12的源极信号布线。电压绝对值大于高频信号的电压振幅的信号 并且电压极性为正。施加信号的基板部件12的红外图像由图像拾取装置15拍摄。在图像处理装置16中,从图像馈送的图像数据 拾取装置15形成相对于红外线发射的红外图像,红外图像被分成与布线图案大小相等的多个区域。 在控制装置18中,将各分割区域的图像与多个相邻区域的图像进行比较,并检测差异。 当检测到差异时,判断该区域存在缺陷。

    • A manufacturing method of a liquid crystal display of the present invention is a manufacturing method of a liquid crystal display having a glass substrate provided thereon with a matrix of thin film transistors, each having a semiconductor film pattern formed by photo-etching a high-resistance semiconductor film and a low-resistance semiconductor film, and a third metal film serving as a source metal film layer layered on the semiconductor film pattern, in which the semiconductor film pattern is formed on the glass substrate first, and thence the third metal film is layered on the glass substrate. Consequently, a liquid crystal display can be manufactured with a fewer number of manufacturing steps while at the same time the manufacturing costs can be saved by preventing a decrease in the yield caused by film separation.
