Display apparatus

A display apparatus comprising:

• an eyeglass-type frame worn by a head of a viewer;
• and
• an image display apparatus attached to the frame,
• wherein the image display apparatus includes
• an image formation device, and
• an optical device on which light that exits from the image formation device is incident, through which the light is guided, and out of which the light exits,
• the frame is formed of a front portion, two temple portions extending from both ends of the front portion, a nose pad, and an attachment member,
• the attachment member includes
• a box-shaped first member having at least a first side surface, a second side surface extending from one side end of the first side surface, a third side surface extending from the other side end of the first side surface, a fourth side surface connecting the second side surface and the third side surface to each other, and a bottom surface and
• a second member having at least a first side surface, a second side surface extending from one side end of the first side surface, and a third side surface extending from the other side end of the first side surface,
• the first side surface of the first member is attached to a central section of the front portion,
• the nose pad is so attached to the fourth side surface of the first member that the nose pad is movable upward and downward,
• the optical device is attached to the first side surface of the second member, and
• with the second side surface of the second member facing the second side surface of the first member, and the third side surface of the second member facing the third side surface of the first member, the second member is so attached to the first member that the second member pivotally moves around an axial line parallel to a line connecting centers of eyeballs of the viewer.
