[Problem] To provide a uniaxially stretched multi-layer laminate film with a higher brightness in the front direction as compared with the prior art and a uniaxially stretched multi-layer laminate film laminate body formed therefrom. [Solution] Provided is a uniaxially stretched multi-layer laminate film composed of 251 or more layers in which a first layer and a second layer are alternately laminated, wherein the first layer is a layer composed of a polyester containing a 2,6-naphthalene dicarboxylic acid component as a constituent component; the second layer is a layer composed of a thermoplastic resin as a constituent component; the thermoplastic resin is a resin having an average refractive index of 1.60 or more and not more than 1.65 and having negative optical anisotropy or isotropy; an S polarization component has an average reflectance of 90% or more relative to the incident polarized light at an angle of incidence of 0 degree and 50 degrees, respectively; and a P polarization component has an average reflectance of not more than 15% relative to the incident polarized light at an angle of incidence of 0 degree and an average reflectance of 20% or more relative to the incident polarized light at an angle of incidence of 50 degrees. |
