Patent ID: 7359015

Claim:
A structure of a liquid crystal area for an improved, low-cost, transflective liquid crystal display (TLCD), the liquid crystal area structure consisting of: a transmissive portion and a reflective portion in the liquid crystal area of the transflective LCD; a serpentine wall structure; a set of independent regions in a liquid crystal cell selected from at least one reflective (R) region and at least one transmissive (T) region, wherein the serpentine wall structure separates the set of independent regions in the liquid crystal cell; and a first liquid crystal material in the reflective (R) region and a second liquid crystal in the transmissive (T) regions, wherein the only difference between the first and second liquid crystal material is that the birefringence change in the reflective region is one-half of the birefringence change in the transmissive (T) region so that identical transmittance and reflectance for the set of independent regions are achieved.
