OPTICAL FILTER FOR AN ORGANIC ELECTROLUMINESCENCE DEVICE

The present invention relates to an optical filter for lighting of an organic electroluminescence device (OLED) and an OLED lighting including the same. The present invention provides the optical filter for the OLED lighting, which includes: a substrate film, a light diffusing film or an anti-reflective film formed on one surface of the substrate film, and an adhesive layer formed on the other surface of the substrate film; and at least one dye allowing the light diffusing film or the anti-reflective film, the adhesive layer, or both to absorb a specific wavelength band. The optical filter according to the present invention minimizes the loss of brightness while realizing a desired color for the OLED lighting in an off-state, thereby providing a decoration function. In addition, the optical filter can be effectively used as a front optical filter since color purity of light in a luminous state of the lighting can be improved.
