Abstract
A reflector has protuberances and recesses in each pixel region. The distances between the respective peaks of each two adjacent protuberances in the pixel region are distributed in the range from 5 μm to 15 μm. The incidence of peak distances within the range of ±0.5 μm from the most frequent peak distance ranges from 40% to 80%, and the area of regular reflection surfaces of the reflector tilted at angles of 4.5° or less to the principal surface of a substrate in the pixel region accounts for 35% or less of the area of the pixel region.
