Abstract
Disclosed are a substrate including a quantum rod film, a method for manufacturing the substrate including the quantum rod film, and a display panel. Quantum rod assemblies included in the quantum rod film are arranged sequentially on the substrate, and meanwhile lights of different wavelengths can be obtained by adjusting sizes of the quantum rod assemblies. The quantum rod film disclosed corresponds to a combination of a polarizing layer and a color filter layer in the prior art. Thus, a thickness of the display panel can be reduced, and meanwhile production costs can be reduced. Besides, since quantum rods have high light conversion efficiency, a light utilization rate can be improved to enable the display panel to have a high color gamut and a high luminance.
