Abstract
A color filter having patterns for aligning a mask and a method of manufacturing the same. An align key pattern causes a step difference in height of an overlaid resist layer which, in turn, diffracts a laser beam. The diffracted light is detected to generate an alignment signal to which a mask for exposing the subsequent resist layer is aligned.
