-182689 and Japanese Unexamined Patent Publication No. 60-205989. As a means of activating and encapsulating a phosphor in a porous film formed by anodizing, the porous film is immersed in a phosphor salt solution such as a europium salt solution or a terbium salt solution, and then re-anodized. method can be adopted. In such a method, in order to prevent the phosphor sealed in the porous film from leaking out, the pores filled with the phosphor are sealed, and the fluorescent material inside the pores of the porous film is sealed. In order to increase the amount of encapsulation and stability, it is also possible to perform a secondary anodic oxidation treatment at a lower voltage after the first anodization treatment step to form even finer encapsulation holes at the bottom of each hole.
