The present application is based on, and claims priority from JP Application Serial Number 2019-101039, filed May 30, 2019, the disclosure of which is hereby incorporated by reference herein in its entirety.

BACKGROUND

1. Technical Field

The present disclosure relates to a wearable display device that provides a virtual image and the like to a viewer.

2. Related Art

As a coupling method for transmission in a wearable display device, a configuration using a harness cable structure in a see-through head-mounted display (HMD), which is an aspect of wearable display devices, is known (JP-A-2015-126336).

In the case where a harness cable structure is used as in the device of JP-A-2015-126336, the harness cable may be thick and heavy in an HMD, which is strongly desired to be downsized. For example, in the case where a cable is laid from one side to the other in the left-right direction in a wearable display device having paired configurations corresponding to the left and right eyes, the thickness of the cable is required to be small. Further, in the case where the amount of data such as image data is increased in transmission and the processing speed is increased, it is also important to take countermeasures against noise received from the outside.

SUMMARY

A wearable display device according to an aspect of the present invention includes a first display device and a second display device configured to display images correspondingly to left and right eyes, a first flexible board extending from the first display device to the second display device and configured to transmit a signal, and a second flexible board disposed overlapping the first flexible board. The first flexible board includes a surface overlapping the second flexible board and an opposite surface from the surface top of the second flexible board, the opposite surface being shielded, and the second flexible board includes a surface overlapping the first flexible board and an opposite surface from the surface overlapping the first flexible board, the opposite surface being shielded.
