Abstract

An organic light-emitting display apparatus implemented by using a plurality of organic light-emitting diodes on a substrate and including a first pixel and a second pixel respectively emitting light of different colors, includes: a pixel-defining layer including a first opening and a second opening, the first opening defining an emission area of the first pixel, and the second opening defining an emission area of the second pixel; a total reflective layer over the pixel-defining layer, the total reflective layer including a first upper opening corresponding to the first pixel and a second upper opening corresponding to the second pixel; and a planarization layer covering the total reflective layer and having a refractive index greater than a refractive index of the total reflective layer, wherein an area of the first upper opening is different from an area of the second upper opening.
