Abstract
An electro-optical display device comprises two electrode plates disposed in superposed spaced relationship from each other with a clearance therebetween, and a substance which exhibits an electro-optical effect, such as liquid crystal material, disposed within the clearance. A plurality of display electrodes are mounted in a predetermined pattern on one electrode plate and a plurality of common electrodes are mounted on the other electrode plate respectively facing predetermined ones of the display electrodes to define therewith display characters. A network of electrical conductors is mounted on the two electrode plates and electrically connected in a predetermined array to the said display and common electrodes. A conductive adhesive electrically connects together, at prescribed junctions, the electrical conductors which are mounted on the two electrode plates. The conductive adhesive comprises a mixture of conductive particles having a size substantially equal to the clearance between said electrode plates interspersed in a non-conductive adhesive. The mixing ratio of the conductive particles does not exceed 60% based on the total volume of the conductive adhesive.
