Abstract
A brightness enhancement component includes a substrate and a plurality of prism elements. The prism elements are serially disposed on the substrate. A V-shaped trough is formed between each immediately-adjacent two prism elements. All the V-shaped troughs have their bottom ends disposed within a reference plane. A first prism element group each has a relatively high crest higher than the reference plane by a first height. A second prism element group each has a relatively low crest higher than the reference plane by a second height, wherein each of the first prism element group and each of the second prism element group are alternately arranged on the substrate, the first height is larger than the second height.
