Abstract:
1. A liquid crystal display element in which a liquid crystal layer is interposed between a pair of substrates laminated to each other by a sealing material such that alignment films are opposed to each other with a predetermined gap between the alignment films, wherein a range of dielectric anisotropy Δε of a material for said liquid crystal layer at a measured temperature of 70° C. is −4.5 to −2, wherein a liquid crystal material for said liquid crystal layer is a vertical alignment type liquid crystal and letting Δn be reflective index anisotropy and letting d be a cell gap, a range of a retardation Δnd is from 0.34 to 0.55 μm and further wherein with respect to 100 parts by weight of a base material for a sealing material, content of a photo-radical polymerization initiator is less than 0.05 weight percent.
