1. A head-mounted display comprising:
- a planar backlight for producing and emitting planar light, a light-speed controlling element disposed in front of the planar backlight for controlling a speed of incident light so that the incident light propagates parallel or substantially parallel to an optical axis;
an image-forming element disposed in front of the light-speed controlling element for forming an image; and
a Fresnel lens disposed in front of the image-forming element for focusing the image onto an eyeball.

Abstract
A head-mounted display (HMD) using retinal direct projection that provides a small size and lightweight by changing the configuration of optical components and optical arrangement. The HMD includes: a planar backlight for producing and emitting planar light; a light-speed controlling element positioned in front of the planar backlight for controlling the speed of incident light so that the light propagates parallel or near parallel to an optical axis; an image-forming element disposed in front of the light-speed controlling element for forming an image; and a Fresnel lens placed in front of the image-forming element for focusing the incoming incident onto an eyeball.
