  • Patent number: 5209688
    Abstract: A plasma display panel is disclosed, which comprises a pair of insulating substrates with a predetermined space therebetween; a group of anode electrodes and a group of cathode electrodes formed on the inner side of each of the insulating substrates in such a manner that the groups of the electrodes are normal to each other; and barriers formed on the insulating substrate having the anode electrodes thereon by photolithography. Since the barriers are formed by photolithography using an ultraviolet-curable resin or positive-type resist, high precison patterns having a line width of 100 .mu.m or less and a line spacing of 100 .mu.m or less can be easily obtained and, thereby, a high resolution plasma display having a decreased picture element area and a wider discharge space can be obtained. When photolithography is used in the formation of the cathode electrodes, further high precision fine patterns can be obtained and further finely detailed pitch of picture elements can be achieved.
