Claim:
1. An electrowetting device, comprising: a device body including a cell; a dielectric layer disposed in the cell and having a hydrophobic surface; an electrode configured to polarize the dielectric layer; and a non-polar liquid disposed on the hydrophobic surface in the cell and a polar liquid non-miscible with the non-polar liquid, wherein the non-polar liquid contains a colored material, and the polar liquid contains non-ionic molecules having a polar portion and a non-polar portion, wherein the non-ionic molecules are molecules having an aromatic ring forming at least part of the non-polar portion, the aromatic ring being linked to the polar portion, and wherein at least one (—CONH—R) group is linked to the aromatic ring, where R is an alkyl group whose number of carbon atoms is 3 to 20.
