Abstract: The present invention provides an unbaked laminate for producing a front plate (1) of a plasma display device, and a method for producing such a front plate (1). The laminate includes a burnable intermediate layer (14), and may include an unbaked dielectric layer (12A) and a photosensitive unbaked spacer material layer (16A). The burnable intermediate layer (14) positions between the dielectric layer (12) and the spacer material layer (16), and may burn up upon baking treatment, enabling removal of residues of the spacer material layer in the region subjected to its removal.
