In a plasma tube array-type display device, a first surface of the intermediate member, which is a flexible and bumpy intermediate member 4 interposed between a plasma tube array and a frame substrate, is attached with the rear surface of the plasma tube array at a top face of a plurality of convex portions provided on the first surface, and a second surface opposite to the first surface is attached with the frame substrate so as to define a screen shape, thereby the plasma tube array can be separated easily from the frame substrate.
