PROBLEM TO BE SOLVED: To provide a half-mirror film for a display which has excellent surface quality and low color saturation, shows little color change depending on visual recognition angles, and achieves excellent reflectivity and transmissivity.SOLUTION: A half-mirror film for a display satisfies all of the following (1) to (4): (1) the half-mirror film is a laminate film that has a layer formed of a resin A (hereinafter referred to as A layer) and a layer formed of a resin B (hereinafter referred to as B layer), is formed by alternately laminating 250 or more layers in total in a thickness direction, contains three or more thick film layers having a thickness of at least 1 μm or more and 20 μm or less, and in which the thick film layer becomes the uppermost layer on both sides; (2) an average reflectance at a wavelength band of 400-700 nm is 40% or more and 80% or less and the sum of the average reflectance and an average transmittance is 90% or more; (3) color saturation in a range of 1 m×1 m on a film surface is 0 or more and 7 or less; and (4) the film has no unevenness with an average height of ±5 nm or more and a major axis of 50 mm or more thereon.SELECTED DRAWING: None |
