Structural color display
摘要:
Disclosed is a structural color display including: (a) a pattern forming member which forms a plurality of cells each lined up in two dimension; and (b) a light transmissive image display sheet comprising a color showing layer which shows a structural color, the light transmissive image display sheet being laminated on the pattern forming member, wherein each of the cells is independently controlled to switch to a light reflective state or to a light absorptive state corresponding to an image pattern to be displayed, provided that the light absorptive state is a state in which a light which enters in the cell through the image display sheet is absorbed; and the light reflective state is a state in which a light which enters in the cell through the image display sheet is reflected and the reflected light is made to enter in a region of the image display sheet corresponding to the cell.
