A method of forming a display panel includes providing a first substrate having a transparent electrode, and a second substrate having a pixel electrode. Subsequently, an alignment material is provided and covers on the transparent electrode and/or the pixel electrode, and a photoelectric twisting layer is provided between the first substrate and the second substrate. The alignment material is first in a non-aligned state, and is radiation-polymerizable. The photoelectric twisting layer does not include any radiation-polymerizable material. Thereafter, a voltage difference is applied to drive molecules of the photoelectric twisting layer, and a radiating process is performed on the alignment material. The twisted molecules of the photoelectric twisting layer induce the surface molecules of the alignment material to arrange in an ordered state, and the alignment material is polymerized according to the ordered state as a first alignment film.
