Kind Code:
A1
Abstract:
An optical lens for guiding light from a light source in a display device is provided, the optical lens comprising a lens body formed of a transparent solid material, the lens body comprising a light-emitting section comprising a curved surface that is convex when viewed from a position exterior to the lens body, and a light-incident section connected to the light-emitting section at a light-emitting port and comprising a light-incident surface opposing the light-emitting port, wherein an area of the light-incident surface is smaller than an area of the light-emitting port; wherein the curved surface is positioned such that all projections of the light-incident surface through the light-emitting port may be projected onto the curved surface. The technology relates to an optical member and to an illumination unit, a wearable display (head-mounted display), and an image display apparatus using the same.
