Airtight container and image displaying apparatus using the same

Abstract

An airtight container includes a front substrate, a rear substrate opposite to the front substrate, a plurality of spacers arranged between the front substrate and the rear substrate with the spacers having a predetermined interval therebetween, and a frame provided between the front substrate and the rear substrate and surrounding the plurality of spacers, and of which an internal space surrounded by the front substrate, the rear substrate and the frame is maintained at pressure lower than atmospheric pressure, wherein both the front substrate and the rear substrate are made from glass material, the airtight container satisfies H1<H2<H3, and 1.3(H2−H1)/L<(H3−H2)/W, where H1 is an average height of the spacers, H2 is a height of an edge of the frame on a side of the internal space, H3 is a height of an edge of the frame on a side opposite to the internal space, W is a width of the frame, and L is the predetermined interval.
