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 a T and b T , respectively, and when in reflected light, displayed value b is designated as b r , in the transmitted light, a T and b T are in the range of −2≦a T ≦2, and −2≦b T ≦1.3 and the difference between the displayed value b to the transmitted light and the reflected light is |(b T −b r )|<10. |
