Discussed is a display device including a substrate having a first region and a second region, an anode at the first region, an organic layer at the second region and at the first region, a cathode on the organic layer of the first region, a bank between the first region and the second region, an optical compensation layer on the cathode of the first region and the organic layer of the second region, and an encapsulation layer on the optical compensation layer at the first region and the second region. The cathode is interposed between the optical compensation layer and the organic layer over the first region.

Display device comprising optical compensation layer at light-emitting unit and transmissive unit

Discussed is a light-emitting display device, which emits light unchanged by maintaining a cavity of internal light using reverse cavity characteristics through an optical compensation structure, and achieves high luminance characteristics despite a change in a viewing angle, prevents external light from being reflected, and is excellent in terms of efficiency and lifespan by combining the optical compensation structure with a color filter structure. The optical compensation structure includes at least one first layer having a first refractive index and at least one second layer having a second refractive index greater than the first refractive index, the first layer being thicker than the second layer.

Light-emitting display device comprising optical compensation structure on transmissive electrode

Discussed is a display device for improving both transmittance and efficiency of light that is transmitted through a light-emitting unit and a transmissive unit due to a phase difference of π at an interface between an organic layer and an optical compensation layer of the display device.

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.

Apparatus for fabricating alignment film for improving alignment force of a liquid crystal and method for fabricating liquid crystal display panel using the same

A liquid crystal display device includes a liquid crystal panel having an upper substrate and a lower substrate that face each other with a layer of liquid crystal molecules therebetween, and a liquid powder display panel at a lower surface of the liquid crystal panel for blocking light.

Liquid crystal display device

Provided are an in-plane switching mode liquid crystal display device and a method for manufacturing the same. The device comprises a thin film transistor array substrate, a color filter substrate, and a liquid crystal. The thin film transistor array substrate has a common electrode and a pixel electrode arranged in an alternating pattern with each other, and has a first alignment film provided on the common electrode and the pixel electrode so as to align liquid crystal molecules in a vertical direction. The color filter substrate faces the thin film transistor array substrate, and has a second alignment film that aligns the liquid crystal molecules in a vertical direction. Liquid crystal is injected between the thin film transistor array substrate and the color filter substrate.
