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<SUB>T </SUB>and b<SUB>T</SUB>, respectively, and when in reflected light, displayed value b is designated as b<SUB>r</SUB>, in the transmitted light, a<SUB>T </SUB>and b<SUB>T </SUB>are in the range of -2<=A<SUB>T</SUB><=2, and -2<=B<SUB>T</SUB><=1.3 and the difference between the displayed value b to the transmitted light and the reflected light is |(b<SUB>T</SUB>-b<SUB>r</SUB>)|<10.
