A pseudo-luminous panel has a substrate and a thin film optical color filter formed all over the main surface of the substrate with or without a reflecting film interposed therebetween. The main surface of the substrate is formed by obliquely downward and upward band-like surface portions alternately arranged side by side in a vertical direction. Obliquely downward band-like surface portions of the reflecting film, formed on the obliquely downward band-like surface portions of the substrate, or the obliquely downward band-like surface portions of the substrate are each a smooth reflecting surface. Obliquely upward band-like surface portions of the reflecting film, formed on the obliquely upward band-like surface portions of the substrate, or the obliquely upward band-like surface portions of the substrate are each an irregular or uneven reflecting surface. With the pseudo-luminous panel of such a structure, it is possible to prevent that a pattern on the panel is too dazzling in the daytime and too dark at night to recognize in a predetermined hue when the panel is disposed above ground outdoors.
