A light-guiding device configured to accept image light through a light incidence part, guide the image light through reflection, and emit, to outside through a light emission part, the image light that is guided, the light-guiding device comprising:
- a protective member having a sheet shape and configured to cover a body member in a region corresponding to an optical surface of a surface of the light-guiding device, wherein
- an adhesive layer is formed between the body member and the protective member,
- wherein the adhesive layer is an elastic member that restores to an original shape in a state where no external force is applied.
A light-guiding device configured to accept image light through a light incidence part, guide the image light through reflection, and emit, to outside through a light emission part, the image light that is guided, the light-guiding device comprising:
- a protective member having a sheet shape and configured to cover a body member in a region corresponding to an optical surface of a surface of the light-guiding device, wherein
- an adhesive layer is formed between the body member and the protective member,
- wherein the protective member is fixed to a side surface of the body member with the adhesive layer between the body member and the protective member, the side surface being a surface at which no optical surface is formed.
A method of manufacturing a light-guiding device configured to guide image light through reflection, the method comprising:
- disposing a protective member having a sheet shape on a body member of the light-guiding device with an adhesive layer between the body member and the protective member in a region corresponding to an optical surface of a surface of the light-guiding device, wherein the adhesive layer is an elastic member that restores to an original shape in a state where no external force is applied.
