Abstract: A display apparatus including a light-emitting device is discussed. A device planarization layer, a plurality of micro-lenses, a color filter, a black matrix and an optical lens can be disposed on the light-emitting device. The color filter and the optical lens can overlap the light-emitting device. The black matrix can be disposed side by side with the color filter between the light-emitting device and the optical lens. An upper surface of each micro-lens toward the color filter can include a lens groove. The lens groove of each micro-lens can have a conical shape with a concave side. Thus, in the display apparatus, luminance and efficiency according to a viewing angle can be improved.

Abstract: An alignment film and method of fabricating the alignment film are disclosed. A photosensitive alignment material is spread on an LCD array substrate or color filter substrate and partially cured. A soft mold is aligned on the partially cured alignment material. The soft mold has a concavo-convex pattern with grooves and projections. The alignment material is exposed to ultraviolet radiation through the soft mold and then developed. The differences between the indices of refraction of the soft mold and air cause interference in the ultraviolet radiation, leading to periodic variations in the exposure intensity of the alignment material. These variations result in crests and troughs being formed when the alignment film is developed. The developed alignment film is then cured.
