  • Publication number: 20130301129
    Abstract: An optical film includes: a polarization layer; a first phase retardation layer having an optic axis at an angle in a range from about 17 degrees to about 27 degrees or from about ?27 degrees to about ?17 degrees with respect to a transmission axis of the polarization layer; and a second phase retardation layer having an optic axis at an angle in a range from about 85 degrees to about 95 degrees with respect to the transmission axis of the polarization layer. The polarization layer, the first phase retardation layer, and the second phase retardation layer are deposited in sequence, the first phase retardation layer is a half-wave plate, the second phase retardation layer is a quarter-wave plate, and out-of-plane retardation values of the first phase retardation layer and the second phase retardation layer for incident light having the standard wavelength have opposite signs.

  • Publication number: 20100266838
    Abstract: A method for fabricating a conductive film, and a conductive film fabricated by the same. The method comprises: preprocessing carbon nanotubes by at least one of a cutting step using ultrasonic wave, and a chemical reaction step with acid; dispersing the carbon nanotubes in a solvent; mixing metal wires with the carbon nanotubes dispersion solution; and forming an electrode layer by coating the mixed resultant on a substrate. Accordingly, can be easily fabricated the conductive film having high transmittance and high electric conductivity.
