A one-eye viewing type head-mounted image display device (1) that is compact and comfortably wearable consists mainly of a viewer (2) and an elastic member (38). The viewer includes an LCD (13), a main prism (32), a see-through prism (33), a frame (10), and a microphone (18). The main prism conducts an image, which is displayed on the LCD, to make the image viewable with either the user's right eye or left eye. The see-through prism is bonded to the main prism, transmits extraneously light, and conducts the light to a users eye. The frame bears the LCD at a predetermined position relative to the prisms. The microphone is mounted in the frame. The elastic member includes a nose rest (38a) which supports the viewer so that the viewer will be located at a predetermined position in front of the user's eye.
