Wearable image display device

A wearable image display comprising:

• an image light output unit for outputting an image as image light;
• an image light transmission unit for transmitting the image light output from the image light output unit;
• an image light emitting unit for emitting the image light transmitted from the image light transmission unit to the outside;
• wherein:
• the image light output unit and a part of the image light transmission unit constitutes an image source side section;
• the rest of the image light transmission unit and the image light emitting unit constitute an image display side section;
• the image source side section and the image display side section are separately divided into unit structures,
• the image light output unit includes:
• a light source,
• a light control component for controlling the light from the light source to make a controlled light, and
• a reflective image modulation device for reflecting the controlled light to output the image light;
• the image light transmission unit includes:
• a polarization beam splitter for reflecting the controlled light from the light control component to the reflective image modulation device,
• a light reflector for reflecting the image light from the reflective image modulation device passing through the polarization beam splitter to the polarization beam splitter side,
• a quarter-wave plate disposed between the polarization beam splitter and the light reflector,
• a transit optics for relaying the image light from the reflective image modulation device, passing though the polarization beam splitter, passing though the quarter-wave plate, reflected by the light reflector, passing though the quarter-wave plate again and reflected by the polarization beam splitter, and
• a light guide plate for guiding the image light relayed by the transit optics to the image light output unit;
• the image light output unit includes:
• a plurality of half mirrors disposed in a light guide plate for emitting the image light guided in the light guide plate to the outside;
• the image source side section includes the light source, the light control component, the reflection type image modulation device, the light reflector and the quarter-wave plate in a unit structure;
• and
• the image display side section includes the polarization beam splitter, the transit optics, the light guide plate, and the plurality of half mirrors in a unit structure.
