摘要： A light guide includes: a light guide board configured to allow light incident on an optical entrance to propagate through the light guide board, the light guide board including: the optical entrance; a first face; and at least one partial reflection layer within the light guide board and tilted to the first face. The at least one partial reflection layer is configured to reflect a part of light incident on the at least one partial reflection layer at an incident angle of greater than or equal to a critical angle θr to allow the reflected light to exit the light guide board through the first surface while transmitting therethrough a remainder of the light incident on the at least one partial reflection layer. Formula below is satisfied: θr=sin−1(n2/n1) where θr is the critical angle; n1 is a refractive index of the light guide board; and n2 is a refractive index of the at least one partial reflection layer.

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.
