    摘要： While the memory amount is reduced through minimizing correction data prepared in advance, the capability of uniformity correction can be improved, compared to a related art. Correction data for correcting display unevenness between pixels for representative pixel points is stored. Correction data for pixels except for the representative pixel points is calculated by interpolation. The representative pixel points are arranged with a higher density in a pixel region with relatively finer display unevenness.
