Abstract
An organic light-emitting display apparatus includes a display area including first and second pixels. A plurality of photo sensors is arranged in an outer area of the display area. The first pixel includes a first pixel electrode, an opposite electrode, and a first emission layer between the first pixel electrode and the opposite electrode. The first pixel electrode, the opposite electrode, and the first emission layer are arranged on a substrate. The second pixel includes a second pixel electrode, the opposite electrode having a reflectance less than a reflectance of the second pixel electrode, and a second emission layer between the second pixel electrode and the opposite electrode. The second pixel is closer to the plurality of photo sensors than the first pixel. The second pixel electrode includes a first portion in parallel with the substrate and a second portion having a slope with respect to the substrate.
