PROBLEM TO BE SOLVED: To provide a testing method for a liquid crystal device with which positioning is excellently performed when performing an acceleration test and reliability of a test result can be maintained. SOLUTION: The testing method for the liquid crystal device includes: modifying a part of a region of an alignment film by irradiating the liquid crystal device having the alignment film disposed between a substrate and a liquid crystal layer with laser light through an optical system; acquiring an image in the modified region of the alignment film through the optical system while moving the liquid crystal device in the optical axis direction of the optical system and defining a reference position on the basis of image information; moving the liquid crystal device by a predetermined movement quantity from the reference position in the optical axis direction and irradiating a part of a region of the alignment film different from the modified region with laser light through the optical system to acquire transmissivity information on the liquid crystal layer; and specifying the focus position of the optical system for the laser light on the basis of the movement quantity and the transmissivity information on the liquid crystal layer.
