Claims12
An electronic device that is wearable on a head of a user, the electronic device comprising:
- a light source unit disposed on a second optical axis parallel to a first optical axis formed when eyes of the user look straight ahead;
- a light source synthesis unit making light emitted from the light source unit travel along the second optical axis;
- a fly eye lens separating the light passing through the light source synthesis unit;
- a light source condenser unit condensing the light separated from the fly eye lens;
- a reflection unit disposed between the light source synthesis unit and the light source condenser unit and reflecting light incident from the light source synthesis unit to the light source condenser unit;
- a polarization unit polarizing the light incident from the light source condenser unit;
- and
- a light projection unit projecting the light passing through the polarization unit onto a display unit,
- wherein the light source synthesis unit is disposed on the second optical axis.
