Abstract

An exemplary electro-wetting display (EWD) device (30) includes a first substrate (31), a second substrate (39) facing the first substrate, a hydrophobic insulator (36) provided between the first and second substrates, a first fluid (33), a second fluid (32) and colored layers (38). The first fluid and the second fluid are immiscible and disposed between the hydrophobic insulator and the first substrate. The second fluid is electro-conductive or polar. The first fluid is located between the hydrophobic insulator and the second fluid. Colored layers may be located between the hydrophobic insulator and the second substrate.
