Abstract
Disclosed is a method of manufacturing a substrate for an organic EL device, the method comprising the step of: filling grooves of the optical element with sol-gel coating solution or organic metal cracking solution when a diffraction gratingis formed on the glass substrate, wherein an encapsulation memberis mounted to the glass substratein order to fill the groovewith the coating solution, and the coating solution is injected into a gap between the encapsulation memberand the diffraction grating, so that the organic EL device can be stably manufactured with low variation between optical properties according to positions of the substrate and with improved luminous efficiency. Further, the present invention provides a method of manufacturing a substrate for an organic EL device having a glass substratewith an diffraction grating, wherein the dispersion solution of particles is applied to the glass substrateto form the diffraction grating, so that the organic EL device can be stably manufactured with low variation between the optical properties according to the positions of the substrate and with the improved luminous efficiency.
