The present specification relates to a composition for forming an optical film, an optical film, and a display device comprising the same.
An electrode in an organic light emitting diode (OLED) is made of a metal element, which causes a problem of significantly reducing a contrast ratio of a display due to high external light reflectance. In view of the above, a circular polarizing plate is laminated to suppress external light reflection, however, this method causes disadvantages of increasing material costs and reducing flexibility as well as failing to flexibly adjust color tones of light emitting colors.
With the purpose of replacing this, a low-cost optical film for anti-reflection introducing a dye and a pigment to an adhesive film has been developed. Currently, such an optical film is inferior in viewing angle properties compared to a circular polarizing plate.
The present specification is directed to providing a composition for forming an optical film, an optical film, and a display device including the same.
One embodiment of the present specification provides a composition for forming an optical film, the composition comprising a compound represented by the following Chemical Formula 1, and a binder resin.
