A phosphor panel is composed of a phosphor layer consisting essentially of phosphor in the form of columnar crystals and a protective layer provided on the phosphor layer via an adhesive layer, in which the adhesive layer has a thickness of 0.3 μm or more and intrudes into the phosphor layer in a depth of 2.0 μm or less.
1. A phosphor panel, comprising a phosphor layer consisting essentially of phosphor in the form of columnar crystals and a protective layer provided thereon via an adhesive layer in contact with the protective layer and phosphor layer, wherein the adhesive layer has a thickness of 0.3 to 3.0 um and intrudes into the phosphor layer to a depth of 0.3 to 2.0 um.
2. The phosphor panel of claim 1 , wherein the protective layer has a thickness in the range of 1 to 10 μm.
3. The phosphor panel of claim 1 , wherein the protective layer is a resin film.
4. The phosphor panel of claim 1 , wherein a moisture-proof layer made of inorganic substance and having a moisture permeability of 1 g/m 2 day or less is provided on at least one surface of the protective layer.
5. The phosphor panel of claim 1 , wherein a stimulating light-antireflection layer is provided on at least one surface of the protective layer or of the moisture-proof layer.
6. The phosphor panel of claim 5 , wherein the moisture-proof layer has a function as the stimulating light-antireflection layer.
7. The phosphor panel of claim 4 , which comprises a support, the phosphor layer, the adhesive layer, the moisture-proof layer and the protective layer, placed in order.
