Abstract
Disclosed herein is a quantum rod backlight module for a liquid crystal display. The quantum rod backlight module includes a quantum rod layer disposing at one side of a backlight source and comprising a plurality of quantum rods, wherein the major axes of the plurality of quantum rods are aligned along a direction parallel to a surface of the quantum rod layer; a first micro-prism layer including a plurality of first parallel strip-shape prisms, and a second micro-prism layer including a plurality of second parallel strip-shape prisms, wherein both of the alignment directions of the first parallel strip-shape prisms and the second parallel strip-shape prisms are perpendicular to the direction of the major axes of the plurality of quantum rods, and the retardations of the first micro-prism layer and the second micro-prism layer are zero.
