Abstract
A head-mounted display includes an image display device displaying an image, a mounting member that is fixed to a head of a user, a first ball joint capable of moving and holding the image display device relative to the mounting member and a second ball joint. The first ball joint can move the image display device relative to the mounting member with a first degree of freedom or a third degree of freedom smaller than the first degree of freedom. A socket can selectively change a degree of freedom of the first ball joint between the first degree of freedom and the third degree of freedom.
