Abstract
An electrowetting display device that includes a display member having: a first substrate in which at least one surface has conductivity, a second substrate which is disposed to face the conductive surface of the first substrate, a hydrophobic insulating film which is provided on the conductive surface of the first substrate, an oil, which is non-conductive, provided between the hydrophobic insulating film and the second substrate so as to be movable on the hydrophobic insulating film, and containing a nonpolar solvent and a methine dye including two dye mother nuclei that are linked through a linking group having a methine unsaturated chain, and a hydrophilic liquid which is conductive, provided between the hydrophobic insulating film and the second substrate so as to be in contact with the oil.
