Abstract
A main unit of an HMD that is a head-mounted picture display device of the present invention can be mounted on the observer's head. The main unit has a front cover and back cover constituting a housing body that accommodates LCDs serving as picture display members, and prisms. The front cover and back cover are unitedly secured by inserting headed screws from the back cover with projections fitted into inner circumferential parts. The front cover has two surfaces lying along lines inclined upward and downward from apices toward the back cover. The main unit is retained at a viewable position, located closely to or in contact with the observer's head, in front of observer's eyes. The adoption of this shape of the housing body permits a lightweight design of the main unit and enables long-term use thereof.
