Abstract

The present invention provides an optical laminate that can contribute to the improvement of display characteristics of VR goggles. A display system according to an embodiment of the present invention comprises: a display element that has a display surface for emitting light representing an image forward through a polarization member; a reflection part that is disposed forward of the display element, includes a reflection-type polarization member, and reflects light emitted from the display element; a first lens part that is disposed on an optical path between the display element and the reflection part; a one-way mirror that is disposed between the display element and the first lens part, transmits light emitted from the display element, and reflects light reflected by the reflection part toward the reflection part; a first retardation member that is disposed on an optical path between the display element and the one-way mirror; and a second retardation member that is disposed on an optical path between the one-way mirror and the reflection part. The polarization member and the first retardation member constitute an optical laminate, and the optical laminate includes the polarization member, a layer functioning as a half-wave plate, and a layer functioning as a quarter-wave plate in the stated order.

Abstract

A ventilation structure 3a comprises a housing 2a and a ventilation component 1a. The housing 2a has at least one stopper 22 that is positioned in the circumferential direction of a ventilation port 21 communicating an internal space 2u of the housing 2a with an external space 2v of the housing 2a, and that protrudes from an outer surface 2s of the housing 2a. The ventilation component 1a comprises: a cylindrical internal member 10a which is mounted on the ventilation port 21 and has a through-hole as a ventilation path between the internal space 2u and the external space 2v; and an external member 30a which is mounted on an outer peripheral part 12b of the internal member 10a and covers the opening of the through-hole. In plan view with the outer surface 2s of the housing 2a as a reference, at least a part of the stopper 22 overlaps the ventilation component 1a without a base end part 22a of the stopper 22 overlapping the ventilation component 1a.
