A front glass substrate and a back glass substrate face each other with a discharge space in between. A phosphor layer is provided on the back glass substrate for colored-light emission by means of a discharge produced in the discharge space. The phosphor layer is formed of a phosphor thin film having visible-light transmission properties. A column-electrode protective layer and a partition wall have black- or dark-colored faces in contact with a face of the phosphor layer opposite a face facing toward the front substrate.
