Description

ABSTRACT:
A liquid crystal display substrate includes a first substrate, a second substrate, terminals, and a conductive region. The first substrate has a large number of pixel electrodes arranged in a matrix. The second substrate is arranged to be opposite to the first substrate and to interpose a liquid crystal with the first substrate and has a counter electrode for performing liquid crystal display by a voltage applied across said pixel electrodes and the counter electrode. The terminals include common electrode terminals arranged at one part of a peripheral portion of the first substrate. The conductive region is formed at a part of the peripheral portion in which the terminals of the first substrate are not formed, and the conductive region is connected to at least one of the common electrode terminals to apply a common potential to the counter electrode. A liquid crystal display device using the above liquid crystal display substrate is also disclosed.
