PURPOSE: A method for forming a light extraction layer, an organic light emitting display device, and a manufacturing method thereof are provided to form the light extraction layer which improves luminous characteristics by only the deposition process without an etching process or an imprinting process. CONSTITUTION: A light extraction layer (120) with an uneven part or a corrugated part is formed on the rear side of a substrate (100). The light extraction layer is formed by using light extraction compositions mixed with silicate sol solutions and titanium oxide sol solutions. A first electrode (110) is formed on the front side of the substrate. An organic layer (130) includes a hole transport layer and a light emitting layer which are successively formed on the first electrode. A second electrode (140) is formed on the organic layer.
