Abstract
The electrowetting display apparatus includes a display unit including: a first substrate at least one surface of which is electroconductive; a second substrate disposed to face the electroconductive surface of the first substrate; a hydrophobic insulation film disposed on the electroconductive surface side of the first substrate; a non-electroconductive oil which is provided between the hydrophobic insulation film and second substrate movably on the hydrophobic insulation film and includes a non-polar solvent and an azamethine-based colorant containing two colorant mother nuclei bonded via a linking group represented by ═N—; and an electroconductive hydrophilic liquid provided between the hydrophobic insulation film and second substrate to contact the oil; in which an image is displayed by applying a voltage between the hydrophilic liquid and the electroconductive surface of first substrate and changing the shape of interface between the oil and hydrophilic liquid.
