We have developed polymer‐dispersed liquid crystal display (PDLCD) driven by ink‐jet printed OFET. Novel pixel design and cell architecture are proposed to obtain enough current to drive PDLCD and high aperture ratio. 4.8 inch color reflective display has been fabricated successfully with the reflectivity of 18 % and contrast ratio of 4:1.
