Abstract
A wide-frame display consisting of a plurality of constituent display cells is described. The display cell comprises a pair of substrates between which a light influencing layer is disposed. The light influencing layer changes its optical property in accordance with an electric field applied thereacross by means of an electrode arrangement. Driving signals are supplied to the electrode arrangement through holes opened in the substrate and receiving leads which make contact with the electrode arrangement at one end and extends from the external surface of the substrate for coupling with a driving circuit for supplying the driving signals.
