An active matrix substrate inspecting device.

摘要

A device and method for inspecting any fault in an active matrix substrate which includes a transparent conductive film on the substrate, an orientation film on the transparent conductive film, a polymer sheet opposite the orientation film with a liquid crystal sandwiched therebetween, a spacer for maintaining a space between the orientation film and the polymer sheet. An electrical modulation is observed in the liquid crystal by applying a voltage across the pixel electrode and the transparent conductive film. <IMAGE>
