PURPOSE: An organic light emitting device and a manufacturing method thereof are provided to form a plurality of sealing layers without repeating a deposition process by using a self-assembly property of a block copolymer. CONSTITUTION: An organic light emitting cell(200) is formed on a substrate(100). The organic light emitting cell includes an anode, a cathode and a light emitting layer. A sealing layer(300) covers the upper side and lateral side of the organic light emitting cell and is formed by alternatively laminating a first sealing layer(310) and a second sealing layer(320). The first sealing layer is made of a first organic material(312) and inorganic materials(314). A second sealing layer is made of a second organic material.
