摘要
An active matrix circuit substrate for liquid crystal or EL display having a drive circuit for each of the pixels. In the proximity of each drive circuit, there is provided an optical control switch for performing control so that a current path between the drive circuit and an external wiring is provided when the ON state is set in. During inspection, light is applied to a predetermined optical control switch so as to turn ON the optical control switch and evaluation is performed by measuring the current passing through the optical control switch.
