Abstract

Abstract An organic thin film display element comprises an organic thin film containing donor moleculaes and acceptor molecules and a pulse voltage source for causing a charge transfer between the donor molecules and the acceptor molecules. The charge transfer varies the optical characteristic of the organic thin film, whereby the organic thin film displays an image.
