  • Methods of manufacturing optical filters and methods of manufacturing organic light emitting display devices having optical filters
    Patent number: 8951700
    Abstract: A method of manufacturing an optical filter includes preparing a substrate having a panel region, a peripheral region, and an alignment region, forming an outer black matrix on the substrate, such that the outer black matrix surrounds the panel region, forming a dummy black matrix on the substrate, such that the dummy black matrix is in the peripheral region while exposing the alignment region, forming a first color photoresist layer on the substrate to cover the outer black matrix and the dummy black matrix, forming a first color pattern in the panel region and an alignment pattern in the alignment region by patterning the first color photoresist layer, forming a second color photoresist layer on the substrate, forming a second color pattern in the panel region by patterning the second color photoresist layer, and forming a third color pattern in the panel region.
