A head-mounted display that can suppress positional misalignment of a display apparatus in the left and right directions, and can reduce the load on a user's nose is proposed. A nose pad assembly H has: a movable portion (M2) having a frame (31), and a nose pad (32) attached to the frame (31); and a support mechanism (M1) that is attached to an apparatus body (10), and supports the frame (31). The support mechanism (M1) supports the frame (31) such that a motion of the nose pad (32) in the front and rear directions is allowed.

This application relates to a method for controlling a curvature of an adjustable curved-surface display and a curved-surface display apparatus. The control method includes: capturing a scene picture information according to an image sensor mounted on a curved-surface display; calculating a location of a viewer in the scene picture information according to a processing unit; calculating an angle between the viewer and a central line of the curved-surface display according to the location; calculating optimal visual angle information according to the angle; and obtaining an optimal curvature according to the optimal visual angle information, to control a display surface bending distance of the curved-surface display.
