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.

Abstract: The present invention relates to liquid display technology, and provides a liquid crystal display screen and a display device. A first and a second optical compensation film are disposed on each side of the liquid crystal layer respectively. By the first optical compensation film, a polarized light obtained from a light non-normally incident into a first polarizing layer is compensated so that the polarized light becomes a first elliptically polarized light. By means of the phase retardation function of the liquid crystal layer, the first elliptically polarized light is converted into a second elliptically polarized light with its polarization direction consistent with that of the first elliptically polarized light and its rotation direction opposite to that of the first elliptically polarized light. By the second optical compensation film, the second elliptically polarized light is compensated into a polarized light capable of being absorbed completely by a second polarizing layer.
