Title:
OPTICAL DEVICE AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/126740
Kind Code:
A1
Abstract:
The present invention provides an optical device which is thin and has high light utilization efficiency, and a compact electronic device which comprises the optical device. Provided is a thin optical device comprising a reflection/polarizing plate, a lens, and an optical rotator, said optical device using rotation of the plane of polarization of linearly polarized light by the optical rotator, and optical transmission and reflection properties of the reflection/polarizing plate, thereby making it possible to achieve a thin optical device with a short total length. Furthermore, the optical device does not use a half mirror and therefore makes it possible to achieve characteristics for high light utilization efficiency, reduce energy consumption by an electronic device, and improve reliability.
