    摘要: Light is directed to a VA (Vertical Alignment) liquid crystal panel whose optical axis is in a direction perpendicular to the panel surface in such a manner that the light is incident obliquely on the VA liquid crystal panel surface, by which birefringence that results only from the liquid crystal layer is artificially generated so that measurement of the thickness (cell gap) of the VA liquid crystal is accurately performed.
