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 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 includes a plurality of pattern elements spaced apart from each other. At least two pattern elements of the plurality of pattern elements have different light absorptivities and/or light diffusivities. The at least two pattern elements 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 plurality of pattern elements may form a group of first pattern elements and a group of second pattern elements. Only the group of first pattern elements may contain the light-absorbing material, and only the group of second pattern elements may contain the light-diffusing material. The groups of first and second pattern elements may be arranged alternately.
