MANUFACTURING METHOD FOR HALF MIRROR USED IN IMAGE DISPLAY SURFACE OF IMAGE DISPLAY DEVICE, HALF MIRROR, AND MIRROR WITH IMAGE DISPLAY FUNCTION

摘要

The present invention provides a manufacturing method for a half mirror, said manufacturing method comprising preparing a transfer material that includes a circularly polarized light reflection layer, laminating a transparent substrate and the surface of the circularly polarized light reflection layer of the transfer material by means of a curing adhesive, and curing the curing adhesive to form an adhesion layer having a thickness of 1.0-5.0 μm, inclusive, wherein the surface of the transfer material which is laminated to the transparent substrate has a pencil hardness of HB or lower. By using a half mirror manufactured by the manufacturing method according to the present invention, it is possible to provide a mirror with an image display function that enables bright, clear image display and mirror-reflected image display.
