1. A method for manufacturing a pixel structure of a display including a first substrate, a second substrate, and a liquid crystal (LC) layer disposed therebetween, and the method comprising: forming a plurality of first, second, and third sub-pixels; forming a plurality of alignment controlling patterns in the first, second, and third sub-pixels; forming a plurality of opaque regions in the first, second, and third sub-pixels and substantially aligned with at least a portion of the alignment controlling patterns, so that the opaque regions are substantially overlapped with the at least a portion of the alignment controlling patterns and area percentages of the alignment controlling patterns shielded by the opaque regions in at least two of the sub-pixels are substantially different from each other.
