A titanium nitride-stripping liquid for stripping a titanium nitride coating film, the titanium nitride-stripping liquid being capable of stripping a titanium nitride coating film even in a semiconductor multilayer laminate having particularly a layer that includes tungsten or a tungsten alloy, without corrosion of this layer is provided, and furthermore, a titanium nitride-stripping liquid which can strip a titanium nitride coating film without affecting an insulating layer is provided. A titanium nitride-stripping liquid including hydrofluoric acid, hydrogen peroxide and water, and further including an inorganic acid other than hydrofluoric acid. According to the present invention, since the titanium nitride-stripping liquid includes an inorganic acid other than hydrofluoric acid, a titanium nitride coating film can be stripped even in the case in which a semiconductor multilayer laminate has a layer that includes tungsten or a tungsten alloy, without corrosion of the layer by the titanium nitride-stripping liquid.

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.
