Abstract: The combiner has a reflecting surface that reflects incident light. When the incident light has an incident angle in a range from 0° to 25°, inclusive, defined as a first value, in a wavelength range from 400 nm to 700 nm, inclusive, the upper limit wavelength of a wavelength range having a reflectance of 90% or more of the reflectance peak of the incident light is shorter than 700 nm. When the incident angle takes a second value in a range from 60° to 85°, inclusive, in the wavelength range from 400 nm to 700 nm, inclusive, the reflectance peak of an S-wave component contained in the incident light has a wavelength shorter than 570 nm.

Abstract: A reflective display device includes a substrate that has a side surface including a surface having arithmetic average roughness of at least 5 μm, and that is formed by injection-molding cycloolefin-based resin, and a vapor-deposited film formed of SiOx (x is 1 or more and 2 or less) formed on a first surface of the substrate. Two corner portions on one side of the substrate each have a curved portion of a radius of at least 1 mm, and two corner portions on another side opposite to the one side of the substrate each have a bent edge portion. The substrate includes a level difference portion where a second surface side portion is formed recessed with respect to a first surface side portion with a parting line as a boundary, where the parting line is positioned in such a proportion that the first surface side portion becomes greater than the second surface side portion on an opposite side of the first surface side portion with respect to a width dimension of the side surface of the substrate.
