  • Patent number: 8149362
    Abstract: A liquid crystal display (LCD) device having an alignment film of which pretilt angle and azimuthal angle can be adjusted without ultraviolet irradiation and a method for fabricating the LCD device are provided. A liquid crystal display having a thin film transistor substrate and a color filter substrate facing each other and a liquid crystal layer sealed between the substrates includes a first alignment film having a pattern which defines a first and second alignment domains on the thin film transistor substrate and a second alignment film formed on the color filter substrate.

  • Publication number: 20110205356
    Abstract: Provided is an optical surface profilometer. The optical surface profilometer includes a Fabry-Perot resonator into which liquid crystals are inserted, a light source which supplies coherent light to the Fabry-Perot resonator, and a convex lens which is disposed in an interference pattern emitting plane of the Fabry-Perot resonator, wherein the coherent light supplied from the light source is incident to the Fabry-Perot resonator, wherein, when the light is incident, the Fabry-Perot resonator emits an interference pattern generated in a resonance mode, and wherein the interference pattern is configured so that a number of circular fringes having the same center are disposed non-linearly. As a voltage is applied to the liquid crystal layer of the Fabry-Perot resonator, an effective refractive index is changed, so that a resonance mode condition of the Fabry-Perot resonator is changed. As a result, a diameter of the interference pattern is also changed.
