An object of the present invention is to provide an optical device, an image display device, and a display device that can provide an image of high image quality. The optical device according to the present invention includes a first light guiding member (40) having a first surface to a sixth surface and including first deflecting means (41) and a second light guiding member (50) having a seventh surface to a twelfth surface and including second deflecting means 51; the first and third surfaces (40A, 40C) are parallel with each other; the second and fourth surfaces (40B, 40D) orthogonal to the first and third surfaces (40A, 40C) are parallel with each other; the seventh and ninth surfaces (50A, 50C) are parallel with an XY plane; light entering from the fifth surface (40E) is totally reflected within the first light guiding member (40), is deflected by the first deflecting means (41), is emitted from the third surface (40C), enters the eighth surface (50B), is totally reflected between the seventh surface (50A) and the ninth surface (50C), is deflected by the second deflecting means (51), and is emitted from the seventh surface (50A); the first deflecting means (41) includes a plurality of first semitransparent layers (42) provided so as to be separated from and in parallel with each other; and letting and , be angles formed between a normal to a first semitransparent layer (42) and an X-axis when the normal to the first semitransparent layer (42) is projected onto an XZ plane and the XY plane, the values of and , are values exceeding zero degrees.

An image processing unit to be applied to a display controller includes a generation unit for generating a display image including a display element corresponding to a virtual image viewed by a user. The generation unit determines the planar shape of the display element such that a size of the virtual image viewed by the user changes on the basis of the viewpoint height of the user. Specifically, when the viewpoint height changes from a reference position to a position Normal or Short lower than the reference position, the generation unit determines the planar shape of an enlarged display element. The planar shapes of the virtual image in a real space viewed by the user may extend in the front direction and the rear direction.

A television enclosure system includes a housing including a rear bezel and a front bezel coupled to the rear bezel, a gasket on the front wall of the front bezel, a panel held within the front bezel with the gasket between a front wall of the front bezel and the panel, at least one retaining bracket connected to a side wall of the front bezel, and at least one bezel clip coupled to the at least one retaining bracket and configured to engage the panel to compress the gasket.

Disclosed is a host box and a split-type television, wherein the host box includes a box body and a cover plate, a circuit board is mounted within the box body, the circuit board includes an external line interface, and the box body is provided with an aperture corresponding to the external line interface; the cover plate is movably mounted at the aperture, and the cover plate can open the aperture so that the external line is directly connected to the external line interface, or the cover plate can close the aperture.
