Patent number: 6543903Abstract: There is provided a reflecting mirror for use in a rear projection display and so on, comprising a glass substrate at least one surface of which is polished to have a predetermined surface waviness (0.05 &mgr;m or less on the measurement condition that the cut-off value is 0.8 mm to 8 mm), and a reflecting film which is formed on the polished surface of the glass substrate by film-forming in order of aluminum (Al), magnesium fluoride (MgF2) and titanium dioxide (TiO2). As a result, it is possible to obtain a reflecting mirror wherein any pattern of light and shade in an image projected on a screen which occurs due to the difference in light intensity resultant from irregularities in the mirror are prevented, and thereby the image quality can be improved.Type: GrantFiled: December 11, 2000Date of Patent: April 8, 2003Assignee: Nippon Sheet Glass Co., Ltd.Inventors: Toshio Akimoto, Hiroshi Nishikawa
