Abstract
A phosphor screen with a smooth-surfaced phosphor layer is formed by casting a phosphor layer in liquid form on a sheet to which the layer adheres without bonding. The exposed surface of the layer is then solidified and bonded to a permanent substrate. The sheet on which the phosphor has been cast is then removed, leaving a smooth exposed surface, which may then be covered with a transparent protective layer.
