  • Publication number: 20120242917
    Abstract: Provided is a shutter panel including a first substrate on which a plurality of electric field forming electrodes are parallel to each other, a second substrate opposed to the first substrate, and a liquid crystal layer disposed on the first and second substrates. Each of the electric field forming electrodes has both side surfaces facing the adjacent electric field forming electrodes, and both side surfaces are provided with protrusion parts protruding toward the adjacent electric field forming electrodes.

  • Publication number: 20120062822
    Abstract: A liquid crystal display includes a first substrate having a first alignment layer, a second substrate having a second alignment layer, a liquid crystal layer having liquid crystal molecules operating in a twisted nematic (TN) mode, a first polarizing film, a second polarizing film, and a phase difference compensation film. The phase difference compensation film has a delay axis to compensate for an undesired phase difference imposed by the NT operating liquid crystal layer on light, traveling through the liquid crystal layer when an ideally fully untwisting electric field is applied to the liquid crystal layer, and the delay axis forms an acute angle with a rubbing direction of the second alignment layer.

  • Publication number: 20110249223
    Abstract: A method of manufacturing a polarizing plate includes fabricating a base film, dyeing the base film by using iodine, stretching the base film to form a polarizing film, firstly drying the polarizing film at a first temperature, and secondly drying the polarizing film while sequentially increasing a temperature from the first temperature to a second temperature higher than the first temperature. The polarizing plate and a liquid crystal display including the same are manufactured through the above method.

  • Publication number: 20100020262
    Abstract: Disclosed is a dual layer prism sheet including two patterned prism sheets adhered to each other with an adhesive layer interposed therebetween. The adhesive layer includes a polymeric adhesive and a lubricant. A liquid crystal display including the dual layer prism sheet is also disclosed. Each pattern on the prism sheet is arranged to make a predetermined angle with a liquid crystal panel.
