DISPLAY BOARD FOR SOLAR CLOCK

PROBLEM TO BE SOLVED: To provide a display having good appearance and quality and excellent in commercial property in which a solar cell and the cross line of an insulating band situated under the display board are never seen through the display board, the display board can be colored, and design variations including color tone can be significantly extended. SOLUTION: In a solar clock display board structure A having a solar cell 11 built in a clock 1 and a solar clock display board B arranged on the surface side of the solar cell 11, the display board B is formed of a color diffusing plate in which the light of a wavelength band for inducing the generation of the solar cell 11 built under the display board, of at least the incident light incident to the display board B, is transmitted through the display board B, the visual confirmation of the solar cell 11 through the display board B from the outside is made difficult, and a color tone can be imparted to the display board B.
