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: n n n n n n n n L n ≥ n n n n ∑ n n i n = n 1 n n m n n n n n d n i n n n tan n n n n ( n n n sin n n - n 1 n n n n n ( n n n n n n air n n n n n i n n n n sin n n n n n n n θ n air n n n ) n n n ) n n n n + n n n d n BM n n n n tan n n n ( n n n sin n n - n 1 n n n n n ( n n n n n n air n n n n n CF n n n n sin n n n n n n n θ n air n n n ) n n n ) n n n n n n n n n [ n Inequality n ] n n n n n n n n n n wherein m represents the number of the upper layers, n i and d i represent a refraction index and a thickness of each of the upper layers, respectively, d BM represents a thickness of the light-shielding layer, n CF represents a refraction index of the color filter layer, n air represents a refraction index of air, and θ air represents a refraction angle in external air after light generated from the light emission layer passes through the color filter layer. |
