AI Technical Summary
Technical Problem
Existing optical systems for display devices, such as smart glasses and AR glasses, have limited regions where observers can view image light, restricting the visibility of the image.
Method used
An optical system with a light guide member featuring a transmissive reflective surface and a deflection section that directs light beams toward an outgoing section, allowing wider observation by replicating light beams through total internal reflection and controlled deflection.
Benefits of technology
Enables observers to view a wider area of light beams, enhancing the visibility and utilization efficiency of image light in display devices.

Abstract
The area from which the observer can observe the light beam from the display element is wider than the area from which the observer can observe it. [Solution] The optical system has a light guide member 103 which has an incident section 111 into which a light beam from the display element 101 is incident, and an outgoing section 112 which causes the light beam that has been incident from the incident section and propagated through the interior to be emitted toward the observation area. The light guide member has a transmissive reflective surface 114 which transmits or reflects the light beam incident from the incident section, and a deflection section 113 which deflects the light beam transmitted or reflected by the transmissive reflective surface toward the transmissive reflective surface, and the transmissive reflective surface directs the light beam from the deflection section toward the outgoing section.
