ABSTRACT:
A plasma addressed display device in which a microsheet glass can be bonded without the risk of cracking and an abnormal local discharge between neighboring cathode electrodes may be prohibited from occurring. The plasma addressed liquid crystal display device is made up of a first substrate having a plurality of first electrodes arranged substantially parallel to one another on its one major surface, and a second substrate having a plurality of second electrodes on its major surface facing the first electrodes on the first substrate. The second electrodes extends substantially parallel to one another and substantially at right angles to the first electrodes, a dielectric sheet arranged between the first and second substrates, a layer of an electro-chemical material provided between the first substrate and the dielectric sheet, a plurality of partitions, as barrier ribs, formed along the second electrodes in a discharge chamber defined between the second substrate and the dielectric sheet, a sealing member arranged between the second electrodes and the dielectric sheet for sealing the discharge chamber, and an insulating film formed in the inside of the sealing member for covering an upper part of the second electrode.
