摘要： An optical film for reducing color shift is provided in front of a display panel. The optical film includes a background layer, and a plurality of lens parts, which are spaced apart from each other, engraved or embossed on the background layer. The lens parts diffuse light incident thereon and then to mix the diffused light with light passing between the lens parts. The lens parts have a depth to width ratio of 0.25 or more, a spacing to pitch ratio ranging from 0.5 to 0.95, and a pitch of 45 μm or less. A display device may include the optical film.

摘要： An optical film for reducing color shift is provided in front of a display panel of an LCD device. The optical film includes a background layer, and a plurality of lens parts, which are spaced apart from each other, engraved or embossed on the background layer. The color of light incident on the optical film from the display panel varies depending on the watching angle and the gray level due to birefringence by a liquid crystal in the display panel. The lens parts diffuse light incident thereon and then to mix the diffused light with light passing between the lens parts. The lens parts have a depth to width ratio of 0.25 or more, a spacing to pitch ratio ranging from 0.5 to 0.95, and a pitch of 45 μm or less. An LCD device may include the optical film.

摘要： An optical filter provided in front of a display panel of a display device includes a background layer and a color shift-reducing pattern formed to a predetermined thickness at the background layer. The color shift-reducing pattern has a plurality of partial areas, and at least two partial areas of the plurality of partial areas have different light absorptivities and/or light diffusivities. The at least two partial areas may contain different amounts of a light-absorbing material that cause the different light-absorptivities and/or different amounts of a light-diffusing material that cause the different light diffusivities. The color shift-reducing pattern may have first and second partial areas, in which only the first partial area may contain the light-absorbing material, and only the second partial area may contain the light-diffusing material. The light-absorbing material may include a green wavelength-absorbing material that absorbs light having green wavelengths from 510 nm to 560 nm. The light-diffusing material may include light-diffusing beads.

摘要： A liquid crystal display for reducing color shift includes a liquid crystal layer, which is disposed between front and rear polarizer layers, and an optical film for reducing color shift, which is disposed between the liquid crystal layer and the front polarizer layer. The optical film includes a background layer and a plurality of lens sections engraved in the background layer, the lens sections being spaced apart from each other. Light emitted from the liquid crystal layer has different colors depending on the viewing angle and the grayscale level owing to birefringence characteristics of the liquid crystal layer. The optical film diffuses a portion of the light incident onto each of the lens sections so that the portion of the light is mixed with another portion of the light passing between adjacent lens sections.

摘要： An optical filter for reducing color shift in a display device includes a background layer made of a light-transmitting material and a light-diffusing pattern formed over the background layer to diffuse light. The light-diffusing pattern is a thin film coating applied along the cross section of the background layer in the depth direction thereof. The light-diffusing pattern is a self-assembled thin film in which the light-diffusing particles are self-assembled. A method of manufacturing the optical filter includes forming a concave-convex pattern layer made of a first light-transmitting material and having a concave-convex pattern, and forming the light-diffusing pattern along the sidewall surface of the concave section of the concave-convex pattern. After the light-diffusing pattern is formed, the concave section is filled with a second light-transmitting material, and the light-diffusing particles are removed from the upper surface of the convex section.
