ABSTRACT:
In the present invention, there is disclosed a reflective mirror whose contrast or resolution performance is equal to that of a surface mirror of a glass mirror for general use and which does not have any problem in reliability of resistance to environment and whose color shift or brightness performance is inhibited from being degraded. For this, in the present invention, a reflective film is formed on a glass substrate by use of silver mirror reaction, and a topcoat is formed of a colorless/transparent resin. At this time, a wavelength of a crest of a ripple indicated by a reflectance characteristic is constituted to substantially agree with that of a green luminescent line. Accordingly, a back projection type video display device which is satisfactory in the contrast or resolution performance can be prepared.
