Display device having a structural colour filter

摘要

Disclosed is a structural color display (10) including: a pattern forming member (17) which forms a plurality of cells (18) each lined up in two dimensions and a light transmissive image display sheet (16) comprising a color showing layer (15) which shows a structural color based on Bragg's Law, the light transmissive image display sheet (16) being laminated on the pattern forming member (17). Each of the cells (18) is independently controlled to switch to a light reflective state or to a light absorptive state corresponding to an image pattern to be displayed. Each cell (18) is composed such that two types of particles differing in coulour are enclosed in each cell frame (18S). The black particles (19B) and the white particles (19W) are electrified in reversed polarity to each other.
