Abstract
(EN)

A method and an apparatus for testing an array substrate that is a component of a liquid crystal display panel. The method and apparatus realize shortening of the test times and also realize reduction of the equipments. In the method and apparatus, while the array substrate is placed in a tester chamber, an electric signal is supplied to a driver circuit part including at least one of a scan line driver circuit and a signal line driver circuit (S1). The electric signal having flowed through that driver circuit part is detected, thereby testing that driver circuit part (S2). An electron beam is irradiated to a pixel electrode that has been charged, and information of secondary electrons discharged from the pixel electrode is used to perform the test as to the pixel electrode (S5).
