Abstract

Provided are an organic light-emitting diode display apparatus and a method of manufacturing the same. In an exemplary embodiment, an organic light-emitting diode (OLED) display apparatus includes a substrate, an OLED device on the substrate, and a capping layer on the organic light-emitting device. The capping layer includes a first capping layer and a second capping layer. The second capping layer includes a first material and a second material. The first material and the second material are different from each other.
