Optical filter for display device and display device having the same

摘要

An optical filter provided in front of a display panel of a display devise includes a background layer (10) and a color shift-reducing pattern formed to a predetermined thickness at the background layer (10). The color shift-reducing pattern has a plurality of partial areas (21,23), and at least two partial areas (21,23) of the plurality of partial areas (21,23) have different light absorptivities and/or light diffusivities. The at least two partial areas (21,23) 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 (21,23), in which only the first partial area (21) may contain the light-absorbing material, and only the second partial area (23) may contain the light-diffusing material. The light-absorbing material may include a green wavelength-absorbing material that absorbs light having green wavelengths from 510nm to 560nm. The light-diffusing material may include light-diffusing beads.
