Light-emitting display device

A light-emitting display device, comprising:

• a substrate;
• a plurality of pixels on the substrate, each pixel comprising an opening area;
• a light extraction pattern disposed in the opening area, the light extraction pattern comprising:
• a plurality of concave portions spaced apart from each other;
• a protruding portion between two adjacent concave portions among the plurality of concave portions;
• and
• an inclined portion between a bottom surface of one of the two adjacent concave portions and a vertex of the protruding portion;
• and
• a light-emitting device layer comprising:
• a light-emitting layer over the light extraction pattern;
• a first area disposed over the vertex of the protruding portion and having a first thickness;
• a second area disposed over the bottom surface of the one of the two adjacent concave portions and having a second thickness;
• and
• a third area disposed over the inclined portion and having a third thickness, wherein the first thickness and the second thickness are larger than the third thickness.
