Title:
HEAD-MOUNTED DISPLAY DEVICE
Document Type and Number:
Japanese Patent JP2018116261
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a head-mounted display device.SOLUTION: A head-mounted display device includes an indicator, a first waveguide element, and a second waveguide element. An image light flux is projected on a projection object. The first waveguide element includes a plurality of first spectroscopic elements. An image light flux from the indicator is made incident on the first waveguide element via a first incident surface. The image light flux converges in a first diaphragm in the first waveguide element. The image light flux separates from the first waveguide element via a first light-emitting surface. The first diaphragm is located in the first waveguide element. The second waveguide element includes a plurality of second spectroscopic elements. An image light flux from the first waveguide element is made incident on the second waveguide element via a second incident surface.SELECTED DRAWING: Figure 1
