Filed: 1997-04-02
Abstract: PROBLEM TO BE SOLVED: To easily view displayed information and to improve the visibility by providing the display section which has the display pattern region having a different reflection scattering characteristic with respect to an adjacent region. SOLUTION: In a display section 4, which is separately provided with respect to a recording region 3, an adjacent region 4b is provided adjacent to a pattern region 4a which is used to display information including characters and pictures. The region 4a is formed by a mirror finished surface. The region 4b is formed by a sattin finished surface having random and minute projections and recessions. When the region 4a is viewed through a transparent substrate 2, reflected light beams are scattered at the portion where the sattin finished surface of the region 4b is transferred. However, no scattering occurs at the portion, where the mirror finished surface of the region 4a is transferred, the contrast against the adjacent portion becomes stronger and viewing is easily performed.  Note that the sattin finished surface and the mirror finished surface are reversed to obtain the same effect. In any event, the pattern 4a and the region 3 are separated and therefore, the adverse effect caused by the optical interference of the pits in the region 3 is reduced and the visibility is improved.
