• a head-mounted display including:
• a display part configured to display an image;
• a head mounting part to be mounted on a head of a user;
• and
• a holder provided to the head mounting part and configured to hold the display part;
• and
• an eyecup formed of material which blocks light or lowers intensity of light, and configured to be attached to the display part,
• wherein the eyecup includes:
• a main body which is elastically deformable;
• a mounting section provided to the main body and to be mounted on the display part;
• and
• a first opening arranged on an opposite side to the mounting section with respect to the main body, the first opening being opened to expose at least a part of the display part,
• wherein the holder includes a holding mechanism configured to hold the display part so as to be movable relative to the head mounting part,
• wherein a magnitude of a force with which the holder holds the display part is equal to or larger than a maximum magnitude of an elastic force which is generated as the main body is elastically deformed in a direction where the first opening and the mounting section approach each other.
