Abstract

Provided is an optical laminate that can contribute to an improvement in display characteristic of a pair of VR goggles. A display system according to an embodiment of the present invention includes: a display element having a display surface configured to emit light representing an image to a front side through a polarizing member; a reflecting portion, which is arranged on a front side of the display element and includes a reflection-type polarizing member, the reflecting portion being configured to reflect the light emitted from the display element; a first lens portion arranged on an optical path between the display element and the reflecting portion; a half mirror arranged between the display element and the first lens portion, the half mirror being configured to transmit the light emitted from the display element and to reflect the light reflected by the reflecting portion toward the reflecting portion; a first retardation member arranged on an optical path between the display element and the half mirror; and a second retardation member arranged on an optical path between the half mirror and the reflecting portion. In an optical laminate including the polarizing member and the first retardation member, transmitted light having a wavelength of 550 nm has an ellipticity of 0.77 or more, which is measured at a polar angle of 30° and an azimuth angle of from 0° to 360°.
