Abstract
The display of the present invention includes an uneven-structure-forming layer having a surface provided with a plurality of concavities or a plurality of convexities respectively provided with flat bottoms and flat tops substantially parallel to the flat bottoms, and a light reflecting layer covering all or a part of an uneven surface of the uneven-structure-forming layer. The uneven-structure-forming layer is provided with two kinds of uneven-structure-forming regions. Each of the two kinds of uneven-structure-forming regions has a constant optical distance between the flat bottoms and the flat tops, but the optical distance is different between the two kinds of regions. The two kinds of uneven-structure-forming regions are alternately arrayed. The optical distances in the two kinds of uneven-structure-forming regions have respective set values which are so selected, when forming the uneven surface of the uneven-structure-forming layer, to form a combination contributing to reduction of a color shift of the display.
