Embodiment Construction

[0048] Hereinafter, the present invention will be described through embodiments of the invention, but the following embodiments do not limit the scope of claims of the present invention. In addition, all combinations of the features described in the embodiments are not necessarily essential to the solution of the invention.

[0049] figure 1 In the diagram, a display device 10 according to one embodiment is schematically shown integrally with a stereoscopic image projected in space. In addition, the drawings used in the description of the embodiments are schematic or schematic for easy understanding. The drawings used for describing the embodiments may not be drawn on an actual scale.

[0050] The display device 10 has an emission surface 71 from which light is emitted. The display device 10 forms the image 6 as a stereoscopic image by the light emitted from the emission surface 71 . The image 6 is a stereoscopic image spatially recognized by the user. In addition, a ster...

Abstract

An optical device comprising: a light conversion unit that converts light from a light source; a light guide plate that guides the light from the light source converted by the light conversion unit in a plane parallel to an exit surface; a deflection unit that passes through the light guide The light guided by the light plate is deflected and emitted from the emitting surface, thereby forming an image, and the light conversion unit condenses or diverges the light emitted from the light source in a plane parallel to the emitting surface, thereby converting it to be emitted from a smaller area The deflection unit forms different images depending on the direction of observation.

Description

technical field [0001] The present invention relates to optical devices. Background technique [0002] A stereoscopically viewable display device (for example, see Patent Document 1). [0003] Patent Document 1: Japanese Patent Laid-Open No. 2012-008464 [0004] The problem to be solved by the invention [0005] The larger the spread angle of the light at each point in the plane parallel to the exit surface in the light guide plate is, the larger the spread (spread) of the light emitted from the light guide plate is. Therefore, it is difficult to emit light in a specific direction from the light guide plate. For example, when a light guide plate is used to realize a binocular or multi-eye system that provides parallax images, the range of viewpoints cannot be limited. Contents of the invention [0006] Solution to the problem [0007] According to the first aspect of the present invention, the optical device includes: a light conversion unit that converts light from ...
