Display device and method of manufacturing the same

A display device comprising:

• a base substrate;
• a plurality of pixels disposed on the base substrate to display an image directly, each of the pixels comprises an organic light emitting device;
• a light collecting member disposed on the plurality of pixels;
• an encapsulation member disposed on the light collecting member such that the light collecting member is disposed between the encapsulation member and the plurality of pixels;
• and
• a color filter disposed between the light collecting member and the encapsulation member,
• wherein the light collecting layer comprises,
• a first light collecting layer disposed on the plurality of pixels and having a first protrusion pattern, the first protrusion pattern being protruded from an upper surface of the first light collecting layer;
• and
• a second light collecting layer disposed on the first light collecting layer and having a second protrusion pattern, the second protrusion pattern being protruded from an upper surface of the second light collecting layer,
• wherein the first protrusion pattern is extended in a first direction substantially in parallel to a major surface defining the base substrate and is arranged along a second direction substantially in parallel to the major surface of the base substrate and crossing the first direction and the second protrusion pattern is extended in the second direction and is arranged along the first direction,
• wherein the first and the second protrusion patterns are protruded to change an optical path of a light which passes therethrough, and
• the first and the second light collecting layers comprise same material.
