The present invention addresses the problem of providing: a half-mirror film for displaying a projected image, said half-mirror film having high adhesion; a laminated glass in which the occurrence of wrinkles in the half-mirror film is suppressed or the adhesion is further improved; and an image display system using the laminated glass. The present invention solves the problem by a half-mirror film for projected image display, the half-mirror film for projected image display having a transparent support and a selective reflection layer that reflects light in a wavelength selective manner, the absolute value of the in-plane phase difference of the transparent support at a wavelength of 550 nm being 10 nm or less, and the absolute value of the in-plane phase difference of the transparent support at a wavelength of 550 nm being 10 nm or less. A heat sealing layer is arranged on the surface opposite to the surface provided with the selective reflection layer of the transparent support body, the heat sealing layer contains thermoplastic resin, and a mixed layer is arranged between the transparent support body and the heat sealing layer and is formed by mixing components of the transparent support body and the heat sealing layer.
本发明的课题在于提供一种密合性高的投影图像显示用半反射镜膜、抑制产生半反射镜膜的褶皱或者密合性进一步高的夹层玻璃及使用该夹层玻璃的图像显示系统。本发明通过投影图像显示用半反射镜膜解决课题,所述投影图像显示用半反射镜膜具有透明支撑体及以选择波长的方式反射光的选择反射层,透明支撑体在波长550nm中的面内相位差的绝对值为10nm以下,在透明支撑体的具有选择反射层的面的相反面侧具有热封层,热封层含有热塑性树脂,在透明支撑体与热封层之间具有混合有两者的成分的混合层。
