ABSTRACT:
A liquid crystal display includes a first substrate having a plurality of pixel electrodes arranged in a matrix, a plurality of row terminals and common electrode terminals arranged on one side of two adjacent sides of the first substrate, a plurality of column terminals and common electrode terminals arranged on the other side of the two adjacent sides of the first substrate; a second substrate arranged to be opposite to the first substrate and to interpose a liquid crystal display with the first substrate and having a counter electrode for performing liquid crystal display by applying a voltage across the pixel electrodes and the counter electrode. The conductive region being connected to at least one of the common electrode terminals to apply a common potential to the counter electrode. Instead of using a common drive circuit, a single conductive region is formed along only a single one of the two remaining sides of the first substrate so as to allow for measuring of at least one of a voltage drop and a voltage signal delay occurring at a substantially central portion of the matrix.
