ABSTRACT:
The present invention provides a head-mount image display apparatus which is maximumly reduced in size so as to arrange eyepiece optical systems in limited spaces such that the eyepiece optical systems do not touch the user's nose. The head-mount image display apparatus comprises LCD for displaying images for left and right eyes, eyepiece optical systems for guiding the images for left and right eyes displayed on the LCD to left and right eyeballs, body of the display apparatus for supporting the LCDs and the eyepiece optical systems for the left and right eyes such that the LCD and the eyepiece optical system for the right eyepiece is arranged at a predetermined distance from the LCD and the eyepiece optical system for the left eye, wherein corners of the eyepiece optical systems, at least which face a user's nose, are each provided with a chamfered portion planed off so as not to touch the user's nose.
