Abstract: An organic light-emitting display apparatus includes a pixel electrode, a light emission layer over the pixel electrode, an opposite electrode covering the light emission layer, a plurality of upper layers over the opposite electrode, a light-shielding layer over the upper layers. A distance L between an edge of an emission area of the light emission layer and an edge of the light-shielding layer when viewed in a thickness direction satisfies Inequality below: L ≥ ∑ i = 1 m  d i  tan  ( sin - 1  ( n air n i  sin   θ air ) ) + d BM  tan  ( sin - 1  ( n air n CF  sin   θ air ) ) [ Inequality ] wherein m represents the number of the upper layers, ni and di represent a refraction index and a thickness of each of the upper layers, respectively, dBM represents a thickness of the light-shielding layer, nCF represents a refraction index of the color filter layer, nair represents a refraction index of air, and θair represents a refraction angle in external air after light generated from the light emission layer passes through the color filter layer.
