A plurality of spacers are arranged between a face substrate and a back substrate of a planar image display device and both ends of each spacer are respectively fixed to the face substrate and the back substrate using a fixing material which contains a conductive component and 10 to 90 wt % of vitrifying component. Due to such a constitution, the display device can ensure the parallelism of both substrates and a panel strength by ensuring a fixing strength and conductive properties of the spacers. Accordingly, the display device can realize the large-sizing of a display size and the high-quality display. The display device also can prolong the lifetime.
