Single Mode Transflective Liquid Crystal Display with Dual Cell Gap Using a Multipurpose Substrate

We describe a single mode transflective liquid crystal display (LCD) having a multipurpose substrate in a dual cell gap configuration. The multipurpose substrate fabricated by a replica molding technique provides the vertical alignment for the liquid crystal molecules without any surface treatment and bi-level microstructures as spacers to maintain different cell gaps in two sub-pixels. The elastomeric multipurpose substrate is thinner and lighert than a typical glass substrate. Our transflective LCD shows no electro-optical disparity between the transmissive part and the reflective part as well as enhanced portability due to reduction over 30% in thickness and weight.
