Abstract

A display device is provided having a layer of liquid crystal in a space enclosed by a rim of sealing material between two supporting plates. One supporting plate has a pattern of electrodes to be driven individually with supply electrodes and a number of external connection electrodes. The supply electrodes and connection electrodes are connected to at least one non-encapsulated IC-crystal provided on the one supporting plate. To provide protection for IC-crystal and to minimize a non-effective display area, the IC-crystals are accommodated in recesses of the rim of sealing material of the display device.
