MASK AND METHOD FOR MANUFACTURING THE SAME, AND SEMICONDUTOR DEVICE

摘要

A mask includes a substrate, an effective pixel formation region and a reference pattern formation region. A pixel pattern for forming a pixel component that constitutes a pixel is arranged in the effective pixel formation region. A reference pattern for indicating a reference position where pixel pattern should be arranged in the effective pixel formation region is arranged in the reference pattern formation region. Pixel pattern is arranged to be displaced from the reference position toward a center side of the effective pixel formation region.
