Abstract:
A colored composition for use in electrowetting displays includes a non-polar solvent and a dipyrromethene dye having a solubility in n-hexane of 1% by mass or higher at 25° C. and 0.1 MPa. In a particular embodiment, an electrowetting display device that employs the colored composition exhibits increased responsiveness, and exhibits suppressed backflow at the time of image display.
