Abstract

Embodiments relate to a quantum rod composition, a quantum rod film, a display device with a quantum rod film, and a method of forming a quantum rod film. The quantum rod film includes a plurality of quantum rods and a polymer with a dipole side chain. Responsive to an external electric field, the major axis of the quantum rods and an axis of the dipole side chain arranges in the same direction. The display device includes a plurality of pixel and common electrodes for generating an electric field, and a backlight unit positioned under a first substrate. Responsive to receiving light from the backlight unit, the quantum rod film emits light polarized in a direction parallel to the major axis of the quantum rods.
