ABSTRACT:
A liquid-crystal display panel having different-pitch transparent electrodes to be inspected, a first inspection region defined for stripe electrodes on a transparent substrate included in the liquid-crystal display panel, and a second inspection region defined for other electrodes, allows for the use of multi-purpose inspection probes arranged at regular intervals to inspect all the electrodes without difficulty. The first inspection region includes a plurality of stripe electrodes arranged at regular first inspection interval, a plurality of stripe electrodes arranged at intervals different from the first interval, with the stripe electrodes connected to first inspection electrodes included in the second inspection region. When the first inspection electrodes are located in the second inspection region, their spacing is arranged at a second inspection interval characteristic of the second inspection region so they can be inspected with inspection probes spaced at the second inspection interval.
