摘要
A test signal is supplied to a test switch provided between a D/A converter for selecting and outputting a gray scale voltage of the driving circuit and an amplifier for amplifying and supplying an output voltage at the D/A converter to set a test mode, and an output voltage of the D/A converter is directly measured by a measuring device through the test switch to measure an ON resistance of a gray scale voltage selection circuit of the D/A converter.
