Abstract
A method of fabricating a light extraction substrate for an organic light-emitting device which can increase the extraction efficiency of light emitted from the organic light-emitting device, thereby improving the overall luminous efficiency of the organic light-emitting device. Water glass is applied on a surface of a glass substrate. The water glass applied on the glass substrate is heat-treated such the surface of the glass substrate is roughened. The heat-treated water glass is removed from the glass substrate. A planarization layer of a glass frit is formed on the glass substrate from which the water glass has been removed.
