Abstract

A blue-phase liquid crystal display with wedge protrusion is proposed. The wedge protrusion is made of organic transparent material with a normal or high permittivity to support the inclined thin electrodes. By using this structure, the operating electric field can be less than 3.0 V/$\mu$m when the cell gap is larger than 10 $\mu$m, and the normalized transmittance is about 80%. The low operating electric field helps to reduce hysteresis effect more, and the high transmittance means high light efficiency.
