Abstract: An optical lens device for a head-mounted display includes a transparent support substrate and a Fresnel lens disposed thereon. The Fresnel lens includes a central lens element and a plurality of prismatic elements arranged relative to the central lens element in a proximal-to-distal manner. Each of the prismatic elements has a base facing toward the support substrate, and a draft facet and a sloped facet extending from the base away from the support substrate to intersect with each other to form an apex. Each of the prismatic elements has a height measured from the base to the apex and not greater than 75 μm. The base has a width not greater than 250 μm. A method and a mold for producing the optical lens device are also disclosed.

Abstract: A light guide plate includes a light guide layer and a first microstructure layer. The light guide layer has a light exit surface, a back surface, and a light incidence surface interconnecting the light exit surface and the back surface. The first microstructure layer is disposed on the back surface, and includes a plurality of first microstructures spaced apart from one another. Each first microstructure has a polygonal planar base, and two first inclined faces and two second inclined faces which extend from the planar base, and which are proximal and distal to the light incidence surface, respectively. Each first inclined face intersects the respective second inclined face at a respective first ridge. Each first ridge cooperates with the planar base to form a first angle that ranges from 5 to 70 degrees.
