Abstract
This invention discloses a liquid crystal display (LCD) device and a method of manufacturing the same. The LCD device comprises a first substrate and a second substrate opposing each other, and a nematic liquid crystal layer disposed therebetween and comprising a nematic liquid crystal and a polymer network. The polymer network is formed by irradiation polymerization of a functional monomer in a nematic liquid crystal mixture. The polymer network can reduce the scattering phenomena caused by the refractive index mismatch between liquid crystal and polymer in the prior LCD devices and significantly reduce the dark-state light leakage, so that the contrast is improved. Moreover, since there is no polymer projection disposed on the alignment layer according to the invention, the dark-state light leakage caused by polymer projections is avoided and thus the contrast is further improved.
