Beschreibung
Zusammenfassung:	Disclosed herein is a quantum rod backlight module for a liquid crystal display; the quantum rod backlight module includes a backlight; a quantum rod layer on a side of the backlight, wherein the quantum rod layer includes a plurality of quantum rods, and major axes of the plurality of quantum rods are aligned in one direction; a first prism layer having a plurality of first prisms of parallel arrangement which are disposed on the light exit side of the quantum rod layer, and a second prism layer having a plurality of second prisms of parallel arrangement which are disposed on a side of the first prism layer; wherein the alignment directions of the plurality of first prisms and the plurality of second prisms are perpendicular to the direction of the major axes of the plurality of quantum rods, and retardations of the first prism layer and the second prism layer are zero; therefore, the polarization of light generated by the quantum rod layer can not easily be destroyed, and has a good brightness enhancement e
