Layered type reflective full-color liquid crystal display element and display device having the element

Abstract

Disclosed is a reflective color liquid crystal display element having a four layered structure. The display element specifically comprises the following layers from an observation side: a single layer of a liquid crystal cell which comprises a chiral nematic liquid crystal composition for the blue color reflection; a single layer of a liquid crystal cell which comprises a chiral nematic liquid crystal composition for the green color reflection; and two layers of liquid crystal cells each of which comprises a chiral nematic liquid crystal composition for the red color reflection. In some of the embodiments, a phase difference plate is inserted between the two liquid crystal cells for the red color reflection.
