  • Publication number: 20080158492
    Abstract: The present invention provides a liquid crystal display (“LCD”) panel and manufacturing method thereof. The LCD panel in accordance with the present invention includes a lower substrate including a thin film transistor and a pixel electrode, an upper substrate including a common electrode facing the lower substrate, a liquid crystal layer formed between the upper and lower substrates, and an alignment layer formed of an inorganic substance containing silicon (Si), oxygen (O), and carbon (C) on the upper and lower substrates. The transmittance of light through the LCD panel is high and is practically independent of the deposition temperature of the SiOC alignment layer over a wide range of deposition temperatures. The deposition of the alignment layer can be performed over a wide range of deposition temperatures while maintaining high levels of light transmission.

  • Publication number: 20070110922
    Abstract: A method of forming the alignment film includes placing an inorganic target and a substrate in a chamber so that the inorganic target and the substrate are parallel to each other, evacuating the chamber to a first pressure, supplying a discharge gas into the chamber and evacuating the chamber to a second pressure higher than the first pressure. Moreover, the method further includes depositing an inorganic film on the substrate by ejecting inorganic particles from the inorganic target.

  • Publication number: 20050094923
    Abstract: The invention relates to a fabrication of an integrated optical isolator using a Multi-Mode Interference (MMI) structure and a cladding layer comprising magneto-optical material, which remove needless reflection generated in the course of light propagation and make short length integration possible. Thus, the invention uses nonreciprocal phase shift effect that optical characteristics are altered according to the direction of light propagation. In order to fabricate a light waveguide optical isolator, an input light should be separated into two light waveguides having the same power. That is, for the purpose of reducing the length of optical isolator device, the waveguide length needed to separate an input light into two light waveguides should be shortened. Since the light waveguide length of MMI structure is much shorter than the length of Mach-Zehnder light waveguide for separating an input light into two waveguides, the length of optical isolator device using MMI structure can be reduced.
