A flat display apparatus with spacers between a first panel substrate and a second panel substrate and a method of manufacturing the same are disclosed. The spacers are interposed between an anode substrate and a cathode substrate. The spacers are each formed to have an elongate sheet structure and to be elastically deformable in the thickness direction thereof. A plurality of projected portions is provided on each of the black stripes of the anode substrate, and each spacer is fastened to the plurality of projected portions by a recoil strength obtained when the spacer is elastically deformed. By this, each spacer is supported in an upright condition on the anode substrate by the plurality of projected portions. There is no need for an adhesive or the like for supporting the spacers in the upright condition.
