Embodiment Construction

[0019] Hereinafter, an example of a wearable display device as an optical device according to an embodiment of the present invention will be described with reference to the drawings.

[0020] Such as Figure 1 ~ Figure 4 As shown, the wearable display device 100 as the optical device of the embodiment is a head-mounted display (HMD) having an appearance like glasses. exist figure 1 Among them, X, Y, and Z are vertical coordinate systems, the +X direction corresponds to the horizontal direction of the binocular arrangement of the observer wearing the wearable display device 100, and the +Y direction corresponds to the vertical direction of the horizontal direction of the observer's binocular alignment. The +Z direction is equivalent to the front or frontal direction of the viewer.

[0021] Such as figure 1 , etc., the wearable display device 100 is an optical device that enables the observer or the wearer US wearing the wearable display device 100 to not only see a virtual i...

Abstract

The invention provides an optical device, a wearable display device, and a light guide unit. Distortion, deformation and the like of each part are suppressed when the device is miniaturized, and sufficient strength can be maintained. This optical device is provided with: a first optical member (light guide member (10a)) and a second optical member (light guide member (10b)) that are included in afirst display device (100A) and a second display device (100B) that display images in accordance with the left and right eyes and guide the images; a central member (50) as a coupling member that couples the light guide member (10a) and the light guide member (10b); and a protruding section (51) that is provided to the central member (50) and extends in the lateral direction (+ / -X direction) in which the light guide member (10a) and the light guide member (10b) are arranged.

Description

technical field [0001] The present invention relates to an optical device applicable to a wearable display device that presents a virtual image to an observer, a wearable display device using the optical device, and a light guide unit applicable to the optical device or the wearable display device. Background technique [0002] For example, as a virtual image display device of a head-mounted display (HMD), which can constitute a wearable display device, it is known that a mounting part is provided at the center of a mirror frame holding a pair of left and right light guide plates, and a mounting part is formed on the mounting part. A virtual image display device in which a nose pad is attached to a cutout (Patent Document 1). [0003] Patent Document 1: Japanese Patent Laid-Open No. 2012-163639 [0004] In the device of Patent Document 1, for example, in consideration of miniaturization of the device, the size of the bridging portion and the central portion also needs to be...
