The purpose of the present technology is to provide a video projection device capable of obtaining a satisfactory video (image) while achieving reduction in power consumption and reduction in size of the device. Provided is a video projection device including at least: a monolithic semiconductor laser array including multiple light emitting units, each of which emits a laser light beam; an optical waveguide that guides the laser light beam in a predetermined direction; a mirror that scans the laser light beam in two axes; and a diffractive element that diffracts the laser light beam in a specific direction in front of an eye and projects the laser light beam on a retina. The multiple light emitting units are respectively optically coupled to different input ports among multiple input ports included in the optical waveguide.

Is addressed. A video transmissive head-mounted display device capable of avoiding danger to a user when worn by the user has an external world image acquired by a first image inputting unit, and the external world image is displayed on a display unit. The head-mounted display device has a second image inputting unit that acquires a binocular image of a wearer. The head-mounted display device is configured so that a control unit determines, from the binocular image of the wearer acquired by the second image inputting unit, that the wearer is awake when both eyes are closed for no longer than a predetermined period of time and that the wearer is asleep when both eyes are closed for a predetermined period of time or longer, and the display unit displays the external world image acquired by the first image inputting unit when the wearer wakes from sleep.

To provide an HMD that provides a wearing comfort and a high degree of detachability regardless of the size of the head of a user. A head-mounted image display apparatus according to an embodiment of the present technology includes a display-section body, a holding section, and a weight section. The display-section body displays an image in front of eyes of a user. The holding section is mounted on a head of the user, and includes a first arm that movably holds the display-section body. The weight section includes a weight, and a second arm that is provided to the holding section and movably holds the weight; and is balanced with the display-section body in the holding section.

The present disclosure relates to a display module, a display device, and an assembling method of the display module. The display module includes: a display panel; a backplane disposed on one side of the display panel away from a light emitting surface of the display panel; a reflective sheet disposed between the display panel and the backplane; and an adapter bracket disposed between the reflective sheet and the backplane, and configured to connect with an external support structure located outside the display module, wherein the adapter bracket has a first surface and a second surface, the first surface is fixed on a surface of the backplane adjacent to the display panel in a surface contact manner, and the second surface supports the reflective sheet.

Provided are: a method of manufacturing an optical element that can display a clear image having no blurriness in AR glasses or the like; and an optical element that is manufactured using this manufacturing method. The manufacturing method include: a step of forming a photo-alignment film, performing interference exposure to form an alignment pattern, and applying a liquid crystal composition to the photo-alignment film to form a first liquid crystal layer; a liquid crystal layer lamination step of forming a photo-alignment film, performing interference exposure to form an alignment pattern, applying a liquid crystal composition to the photo-alignment film to form a liquid crystal layer for lamination, peeling off the liquid crystal layer for lamination from the photo-alignment film, and laminating the peeled liquid crystal layer for lamination on the first liquid crystal layer or the liquid crystal layer for lamination, the liquid crystal layer lamination step being optionally performed once or more; a step of peeling off the first liquid crystal layer from the photo-alignment film; a step of forming an adhesive layer having a surface roughness Ra of 15 nm or less on the light guide plate and/or the first liquid crystal layer; and a step of bonding the light guide plate and the first liquid crystal layer using the adhesive layer.

A display apparatus includes a base, a stand, a head having a display and pivotable between a landscape mode and a portrait mode, a penetration groove, an inner bracket disposed inside the head and having a slit formed therein to face the penetration groove, a shaft including a first extension connected to the stand and extending to an inside of the head through the penetration groove and a second extension extending from an end of the first extension to pass through the slit, a long hole formed in the second extension and extending in a longitudinal direction of the second extension, a guide pin fixed to an inside of the head to pass through the long hole, a slider sliding along the second extension, and a spring disposed on an outer circumference of the second extension and configured to pressurize the slider to maintain contact between the slider and the inner bracket.
