A flat panel display plate (10) comprising part of a liquid crystal display device is tested by overlying the plate with a probe plate (18) comprised of light-transmissive electrode (22) a light-transmissive electrode support (20), and a sensing layer (24). The probe plate in combination with the flat panel display plate (10) realize a conventional liquid crystal display device whose operation depends on the operability of the flat panel display plate. Thus, by observing the liquid crystal display device realized by the combination of the flat panel display plate (10) and the probing plate (18), defects in the flat panel display plate can be detected.
