PROBLEM TO BE SOLVED: To provide a reflector for an LED element substrate, including a reflective layer made of an olefin-based resin, having the physical properties that a reflector of an LED element substrate is required to have, and achieving a superior productivity.;SOLUTION: A reflector 15 for an LED display comprises: a base layer 152 including polyethylene terephthalate as a base resin and having a thickness of 25 μm or more; and a reflective layer 151 laminated on one surface of the base layer, including an olefin-based resin as a base resin, and composed of a foamed resin film of 180 μm or less in thickness. With light incident from the side of the reflective layer 151, the reflectance of light of 450-650 nm in wavelength is 95% or more, and the specular reflectance is 30% or less.;SELECTED DRAWING: Figure 3;COPYRIGHT: (C)2017,JPO&INPIT
