ABSTRACT OF THE DISCLOSURE A pseudo-luminous panel has an optical color filter and a reflecting film formed all over the back thereof. The surface of the optical color filter is formed by obliquely downward and upward band-like surface portions alternately arranged side by side in the vertical direc- tion. The back face of the optical color filter is has obliquely upward band-like back face portions each on the opposite side from one of the obliquely downward band-like surface portions and obliquely downward band-like back face portions each on the opposite side from one of ob- liquely upward band-like surface portions. The obliquely downward band-like surface portions of the optical color filter are each a smooth surface extending straight in the longitudinal section of the panel. The obliquely upward band-like surface portions of the optical color filter are each a rough surface. the obliquely upward band-like back face portions of the optical color filter are each a smooth surface. The obliquely downward band-like surface portions of the optical color filter are each a smooth, irregular or uneven surface. The surface (i.e. the re- flecting surface) of the reflecting film is formed by the back of the optical color filter.
