  • Publication number: 20140168557
    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.
