Abstract

PURPOSE:To produce a mirror having high-precision display part readily, by forming a reflecting film on one side of transparent glass, scanning a focus part of laser beam converged into letter or diagram on the reflecting film, removing the reflecting film on the part and further providing an opaque colored film on the reflecting film side. CONSTITUTION:Cr, Al, TiO2, etc., is formed as a reflecting film 2 on one side of transparent plate glass 1 by sputtering or deposition method. Then, the focus part of laser beam converged by a condenser 4 is scanned on the reflecting film 2 depending upon shape such as letter, diagram, etc., the scanned part is melted, evaporated, the plate glass 1 is shown and a display part 5 such as letter, diagram, etc., is formed. Since the focus part of laser bean is ultrathin, the display part 5 having improved precision of outline is formed. Then, an opaque or semitransparent colored film 7 is bonded to the side of the reflecting film 2 so a mirror 6 having the display part 5 with improved decorative effect is simply produced.

Figure 3 shows the general method.
As shown in a), a plate-shaped metal mask (11) having a slit (Ila) of a predetermined shape is placed on a transparent glass (12). Then, as shown in (b), sandblasting with inorganic or metal particles is performed from the mask (It) side to roughen the glass in the slit (lla) portion. Thereafter, as shown in (c), the mask (11) is removed and a reflective film (13) is formed on one side of the glass surface (b). In this way, a display section (14) that is visible without a reflective function is formed.
