Rupture of distance holding members, aback substrate or a front substrate attributed to atmospheric pressure is suppressed in a display device in which, between the back substrate having cathode lines and plate-member control electrodes and the front substrate, a large number of distance holding members, which maintain distance between the substrates, are mounted in an erect manner. At portions where the distance holding members are brought into contact with the back substrate and/or the front substrate, a buffering/fixing material, which is constituted of a buffering material having high resiliency and an adhesive, is interposed for dispersing the atmospheric pressure applied from the back substrate and the front substrate substantially uniformly. Further, the distance holding members are fixed between the back substrate and the front substrate by a heat treatment and a pressurizing step.
