A CVD apparatus includes a process chamber, a susceptor, an auxiliary supporting part, a gas spray part, and a shadow frame. The susceptor may be in the process chamber to support and heat a mother substrate. The auxiliary supporting part may be mounted on the susceptor in a tetragonal frame form to support and heat an edge of the mother substrate supported by the susceptor. The gas spray part may be in the process chamber to face the susceptor and may spray a process gas to the mother substrate. The shadow frame may cover an edge of the auxiliary supporting part and an edge of the susceptor extending from the edge of the auxiliary supporting part.

A quantum dot includes a seed and a core enclosing the seed. The core is grown from the seed to improve size uniformity of the core. The seed includes a first compound without Cd. The first compound may be GaP. The core may include a second compound including elements from group XIII and group XV. The second compound may be InP. The quantum dot may also include a first shell of a third compound enclosing the core. The third compound may be ZnSe or ZnS. The quantum dot may also include a second shell of a fourth compound enclosing the first shell. The fourth compound may be ZnS when the third compound is ZnSe. Embodiments also relate to a quantum dot including first to third elements selected from XIII group elements and XV group elements and fourth to sixth elements selected from XII group elements and XVI group elements.

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.
