We propose a transflective liquid crystal display (LCD) of the multimode type, which is composed of the hybrid-aligned nematic (HAN) mode in the reflective region and the parallel rubbed vertically aligned (PRVA) mode in the transmissive region. An optimized optical configuration is also proposed. In order to make the reflective and transmissive regions in one pixel independent, an Ar+ ion-beam alignment method was used. We confirmed that the transflective LCD of the proposed multimode type had high reflectance and transmittance, wide-viewing-angle property, and high contrast ratio.
