Method of manufacturing optical film for reducing color shift, organic light-emitting display apparatus using optical film for reducing color shift, and method of manufacturing the same

An organic light-emitting display apparatus comprising:

• a first substrate;
• a plurality of organic emission layers on the first substrate, each of which emitting light at different wavelengths and having a micro-cavity structure causing a resonance phenomenon with respect to light having a corresponding wavelength;
• a sealing layer covering the plurality of organic emission layers;
• a low refractive index pattern layer on the sealing layer, and in which a plurality of micro-lens patterns are embossed;
• a high refractive index pattern layer on the low refractive index pattern layer, the high refractive index pattern layer having a higher refractive index than a refractive index of the low refractive index pattern layer, and in which a shape corresponding to the plurality of micro-lens pattern is engraved;
• and
• a second substrate formed on the high refractive index pattern layer.
