A pseudo-luminous panel has a substrate (1) and a thin film optical color filter (3) 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 (2A) and upward (2B) 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 (2A) 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 (2B), or the obliquely upward band-like surface portions of the substrate, are each a smooth, irregular or uneven reflecting surface. Obliquely downward band-like surface portions (4A) of the thin film optical color filter are each a smooth surface extending straight in the longitudinal section of the panel, and obliquely upward band-like surface portions (4B) of the color filter are each a rough 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 with artificial illumination to recognize in a predetermined hue when the panel is set up out doors high above the ground. <IMAGE> |
