  • Patent number: 11467413
    Abstract: A wearable display device includes an optical device configured to form a virtual image, and a support device configured to support the optical device. The support device includes a first side support including a first temple, a second side support including a second temple, and a front frame extending between tip portions of the first side support and the second side support. The support device includes a flexible member between the tip portion of the first side support and a first end of the front frame and between the tip portion of the second side support and a second end of the front frame. The flexible members cause an interval between the tip portion of the first side support and the tip portion of the second side support to be changeable.
