<P>PROBLEM TO BE SOLVED: To provide a light control film and an optical device having a simple structure in which the manufacturing cost is suppressed, and the incoming of dust is prevented. <P>SOLUTION: The composition is simple and manufacturing cost is suppressed by providing a light control film 10 on the front face of a liquid crystal display device body 13 because through holes 12a, 12b and 12c are formed in a predetermined pattern in the film 11, a peeping is prevented even when a person other than an operator tries to peep in from the both side faces or the upper face of the light control film 10 because the light from the liquid display body 13 is reflected, further, the dust does not come into the light control film 10. The dust does not come into the light control film 10 even when the light control film 10 is installed in an illumination device body, and the film is uniformly illuminated. <P>COPYRIGHT: (C)2004,JPO |
