Abstract
An optically semi-transmission reflection material comprises a resinous film comprising a thermoplastic resin, wherein the sum of total light ray transmittance, T %, and total light ray reflectance, R %, i.e., T+R, is 80 to 100%; an absolute value of their difference is |(T−R)|<50% when displayed value a and displayed value b in transmitted light are designated as aand b, respectively, and when in reflected light, displayed value b is designated as b, in the transmitted light, aand bare in the range of −2≦a≦2, and −2≦b≦1.3 and the difference between the displayed value b to the transmitted light and the reflected light is |(b−b)|<10.
