Abstract
Provided are a windshield glass and a head-up display system in which double images are suppressed even in a case where s-polarized light and p-polarized light are mixed in light incident on the windshield glass in a head-up display. A windshield glass includes: an outer glass plate; a reflective layer consisting of a plurality of layers; a retardation layer; an interlayer; and an inner glass plate, wherein a front retardation of the retardation layer at a wavelength of 550 nm is 280 nm or more and 400 nm or less, and an angle between a direction of a slow axis of the retardation layer and a vertical direction of the windshield glass is 1° or more and 20° or less, or 91° or more and 110° or less.
