Abstract:
Disclosed herein is a quantum rod film for a backlight unit. The quantum rod film includes a quantum rod layer having a plurality of quantum rods wherein major axes of the quantum rods are aligned along a direction; a micro-prism layer having a first refractive index and a plurality of parallel strip-shape prisms disposed at a light incident side of the quantum rod layer; and a birefringent layer on the micro-prism layer. By the refractive index difference between the first refractive index of the micro-prism layer and the extraordinary refractive index or the ordinary refractive index of the birefringent layer, the incident light parallel to the direction of major-axes of the quantum rods will selectively pass through the quantum rod film, and the incident light perpendicular to the direction of major-axes of the quantum rods will reflect to backlight for recycling and increasing the backlight efficiency.
