摘要： A propagation optical system includes: a first optical system; an intermediate optical element; and a second optical system. The first optical system, the intermediate optical element, and the second optical system being sequentially arranged in a direction from the image display element toward the light guide member along an optical axis. The intermediate optical element has a non-rotationally symmetric curved surface, of which shape is non-rotationally symmetric about the optical axis. A cross-sectional shape, of the non-rotationally symmetric curved surface, in a first plane including the optical axis is non-arc shape. The first plane is a plane in which the non-rotationally symmetric surface has a strongest positive power among planes including the optical axis. The propagation optical system is configured to form, between the first optical system and the second optical system, an intermediate image corresponding to an image displayed on the image display element.

摘要： A virtual image display device includes: an image display element that displays an image to be displayed as a virtual image; a propagation optical system that propagates light from the image display element; and a light guide member that guides the light propagated by the propagation optical system. The light guide member includes: a light beam incident part that introduces light including image information from the propagation optical system into the light guide member; an image extractor that extracts the light including image information from an inside of the light guide member; and an image emitter that emits the light including image information to an outside of the light guide member. The propagation optical system includes one or more optical members each having a curved surface shape that is non-rotationally symmetric with respect to an optical axis.

摘要： An object of the present disclosure is to provide a display apparatus (1) that enhances the response speed while suppressing the reduction in durability even when the transmittance control is performed. A display apparatus (1) includes a display unit (10), a plurality of light adjustment devices (140), and a controller (9). The display unit (10) is configured to be attached to a head of a user (A) to display information to the user (A). Each of the plurality of light adjustment devices (140) is configured to change a transmittance to adjust an intensity of light (L′) incident from outside. The controller (9) is configured to independently control the transmittances of the plurality of light adjustment devices (140) separately from each other.
