We have developed a transmissive type of electrowetting display driven by passive matrix. The novel display shows high image quality because it provides high contrast ratio 60,000:1 at display normal direction and wide viewing angle character (CR 20,000 at±70 degree). As the display has a memory characteristic, it also exhibits a feature of low power consumption.

A novel scattering display mode was designed to implement the reflective color LCD with high brightness and high contrast. A twisted PDLC device with a single polarizer was found to show the brightness of <30% and the contrast of <20 at the limited viewing angles.
