OPTICAL PLATE WITH MICROSTRUCTURES

摘要

An optical plate includes a substrate having a light emitting surface, a rear surface opposite to the light emitting surface, and a plurality of microstructures that cooperatively define the light emitting surface and each of which parallelly extends in a light traveling direction. Each of the microstructures includes first and second convex portions and a concave portion disposed between and interconnecting the first and second convex portions, and two adjacent ones of the microstructures are connected. Intersections between the microstructures cooperatively define an imaginary plane, and a lowest point of the concave portion is disposed at one side of the imaginary plane opposite to the rear surface of the substrate.

1. An optical plate, comprising:
a substrate having a light emitting surface, a rear surface opposite to said light emitting surface, and a plurality of microstructures that cooperatively define said light emitting surface and each of which parallelly extends in a light traveling direction, wherein each of said microstructures includes first and second convex portions and a concave portion disposed between and interconnecting said first and second convex portions, two adjacent ones of said microstructures being connected, intersections between said microstructures cooperatively de fine an imaginary plane (S), a lowest point of said concave portion being disposed at one side of the imaginary plane opposite to said rear surface.
