Abstract:
1. A display device comprising: a substrate; a laminate structure formed on the substrate and comprising a plurality of layers including a display region and an outermost layer of the laminate structure, wherein one of the outermost layer of the laminate structure and the substrate constitutes a display side outermost layer; and recessed/projected portions formed at least one of an outermost surface of the display side outermost layer, a display side surface of the display region, and an interface existing between the display region and the display side outermost layer, projected portions of the recessed/projected portions having a mean circle-equivalent diameter ranging from 50 nm to 250 nm with the standard deviation of circle-equivalent diameter of the projected portions being within the range of 10 to 50% of the mean circle-equivalent diameter, and a mean height ranging from 100 nm to 500 nm with the standard deviation of height being within the range of 10 to 50% of the mean height; and the projected portions having a circularity coefficient ranging from 0.6 to 1, and an occupation ratio ranging from 20 to 75%, the occupation ratio being a ratio of a total area of projected portions to a total area of the projected portions and flat portions.
