Abstract
A method for manufacturing an active matrix array substrate having a plurality of pixel drive cells, each pixel drive cell includes a pixel switching element and a capacitor element connected to the pixel switching element in series. The method comprising the inspection steps of storing a charge in the capacitor element and detecting the charge stored in the capacitor element by measuring the voltage and comparing the voltage measured with a reference voltage obtained with a good pixel.
