A display device including a housing; a display unit accommodated in the housing; and a control unit configured to cause the display unit to operate in a speaker mode to play a song while the display unit is fully inserted in the housing, receive an image display command, according to the image display command, withdraw the display unit and display a first content corresponding to the image display command in a first region of the display unit, and display a second content of an audio controller for controlling the speaker mode in a second region of the display unit.

An image display apparatus according to the present invention includes an image light generator (100) that emits image light, a first reflection element (11) that the image light from the image light generator (100) is to enter, the first reflection element (11) having a transmitting action and a reflecting action on the image light, a second reflection element (12) that reflects, toward the first reflection element (11), the image light that has entered via the first reflection element (11) and causes the image light to re-enter the first reflection element (11), the second reflection element (12) having a reflecting action on the image light, a light-condensing optical system (20) that converges, toward a position of a pupil of an observer, the image light that has re-entered the first reflection element (11), and a controller (40) that controls a placement angle of the first reflection element (11), the second reflection element (12), or both on the basis of the position of the pupil of the observer.

The object of the present invention is to provide an optical device capable of easily making a sum of grating vectors of optical elements disposed on a light guide plate zero and realizing further improvement of optical characteristics, and a method for manufacturing the optical device.

An optical device (100) of the present invention includes: a light guide plate (1) that totally reflects and guides incident light; a first optical element (5) that is disposed on the light guide plate (1); an input optical element (2) that is disposed on the light guide plate (1) and introduces the incident light into the light guide plate; a second optical element (3) that is disposed on the light guide plate (1) and bends light propagated by total reflection in the light guide plate, in a direction different from a direction of the light; and

an output optical element (4) that is disposed on the light guide plate (1) and emits light propagated by total reflection in the light guide plate, to an outside of the light guide plate. The first optical element (5) has substantially the same grating vector as a grating vector of the input optical element (2), and the first optical element (5) and the input optical element (2) are disposed to face each other with the second optical element (3) interposed therebetween.

A collectible is provided. The collectible includes a viewer operable to display content. The viewer has a body which at least partially encapsulates a processor and a display. The body forms a recess which is operable to at least partially receive a remote. The remote is operable to control the viewer. When the remote is at least partially received within the viewer, the remote and the viewer together form a design which corresponds to a theme. The content displayed by the viewer also corresponds to the theme. The display has a size that is smaller than 2 inches.
