An electro-optic passive display cell including two glass plates positioned spaced from each other with the edges thereof sealed and having an active constituent disposed between said plates. The plates are maintained in spaced and sealed relationship by a frame-shaped distance-piece adhered to the plates by a layer of glass paste solidified by sintering. The cell is formed by applying a high frequency induction current to fuse the frame-shaped piece to at least one plate.
