A Single-Cell-Gap Transflective Display Using a Blue-Phase Liquid Crystal

A single-cell-gap transflective display using a blue-phase liquid crystal (BP-LC) is proposed. In order to balance the optical phase retardation between transmissive (T ) and reflective (R) regions, in-plane protrusion electrodes are formed in both T and R regions on the bottom substrate, and only in the T region on the top substrate. The device exhibits well-matched voltage dependent transmittance and reflectance curves, a low operating voltage, and a wide viewing angle.
