Abstract: A method of manufacturing a photo-alignment layer, includes: disposing a polymer material on a substrate; pre-baking the polymer material disposed on the substrate; irradiating a light to the pre-baked polymer material, to photo-align the pre-baked polymer material; and thermal-treating the irradiated pre-baked polymer material, to harden the irradiated pre-baked polymer material. The thermal-treating includes a first thermal-treatment, and a second thermal-treatment at a higher temperature than the first thermal-treatment.

Abstract: A display includes a substrate, a plurality of subpixels disposed on the substrate and that include organic light-emitting layers, pixel defining films disposed between the subpixels that partition the subpixels, black matrices disposed on the pixel defining films, where the black matrices absorb visible light and emit infrared light; and a sensor layer that receives infrared light emitted by the black matrices and reflected from an external object.
