Abstract
A liquid crystal display device including a pair of transparent baseplates which are opposed to each other. A pair of transparent electrodes are disposed on an inner surface of each of the baseplates. A sealing member is disposed so as to form a chamber between the baseplates for containing therein the transparent electrodes and a liquid crystal. Contact electrodes are disposed on one end portion of the inner surface of each of the baseplates for contacting with a pair of external electrodes to be inserted into the device, from the external electrodes a signal to control optical transmission/screening of the liquid crystal being received. A pair of connecting electrodes are disposed on the inner surface of each of the baseplates for electrically connecting the contact electrodes with the transparent electrodes in order to transmit the signal from the contact electrodes to the transparent electrodes. The device is constructed so that the connecting electrodes are not electrically conducted with each other.
