Organic light-emitting display apparatus

An organic light-emitting display apparatus comprising:

• a pixel electrode disposed over a substrate;
• a light emission layer disposed over the pixel electrode;
• an opposite electrode covering the light emission layer;
• a plurality of upper layers disposed over the opposite electrode;
• a light-shielding layer disposed over the plurality of upper layers, the light-shielding layer not overlapping the light emission layer;
• and
• a color filter layer disposed over the upper layers,
• wherein L is defined by a distance between an edge of an emission area of the light emission layer and an edge of the light-shielding layer when viewed in a viewing direction perpendicular to a major surface of the substrate, wherein the distance L satisfies Inequality below:
