Abstract: A display device may include a substrate, a thin film transistor, a first electrode, a second electrode, and a barrier. The thin film transistor is disposed on the substrate. The first electrode is electrically connected to the thin film transistor. The second electrode overlaps the first electrode. The barrier has a first portion and a second portion. The second portion is disposed between the first portion and the second electrode and is fluorine-doped. A side surface of the first portion is part of a boundary of an opening of the barrier and is hydrophilic. The opening of the barrier is disposed between the first electrode and the second electrode.

Abstract: Provided is a photoalignment film. The photoalignment film may have a fibrous layer that is formed by stacking fibers including a photoalignment material having optical anisotropy in one direction in a state where longitudinal axes of the fibers are arranged in the one direction. The fibrous layer may have a bent surface according to a difference in stacking height between the fibers.
