WEARABLE DISPLAY USING CIRCULARLY POLARIZED LIGHT

The present disclosure relates to a wearable display that is transparent and has a small volume and a wide viewing angle, the display including a circular polarization maintaining and reflecting device configured to pass specific circular polarization light and reflect other circular polarization light while maintaining circular polarization light and a circular polarization inverting and reflecting device configured to reflect the light from the display and passing through the circular polarization maintaining and reflecting device back to the circular polarization maintaining and reflecting device and invert a circular polarization rotation direction in the reflecting process, wherein light rays are reflected twice by using a reflective circular polarization film so that a concave half mirror has a large radius of curvature.
