  • Publication number: 20120042713
    Abstract: The present invention provides a gas sensor, including: a sensor substrate provided with an electrode; and a thin layer of sensor material formed by spraying a solution in which metal oxide nanoparticles are dispersed onto the sensor substrate. The gas sensor is advantageous in that a sensor material is formed into a porous thin layer containing metal oxide nanoparticles having a large specific surface area, thus realizing high sensitivity on the ppb scale and a high reaction rate. Further, the gas sensor is advantageous in that it can be manufactured at room temperature, and the thickness of a sensor material can be easily adjusted by adjusting the spray time, so that a thin gas sensor or a thick gas sensor can be easily manufactured.

  • Patent number: 8081279
    Abstract: Disclosed is a liquid crystal display device including a first substrate where pixel areas are defined, a second substrate facing the first substrate, liquid crystals aligned between the first and second substrates, and spacers that maintain a gap between the first and second substrates. The pixel areas are divided into a plurality of domains along the alignment direction of the liquid crystals by way of domain dividers. Optical characteristics are compensated in different domains, so that the viewing angle of the liquid crystal display device is increased. The display quality of the liquid crystal display device is improved by adjusting the shape and position of the domain dividers and the spacers.

  • Patent number: 7782424
    Abstract: A color filter substrate includes a color filter, a common electrode, a first blocking layer, and a second blocking layer. The color filter is formed in a unit pixel. The first blocking layer corresponds to an outline of the color filter. The second blocking layer is formed in the unit pixel, and under the color filter so to be covered by the color filter, thus decreasing a volume of the color filter. A common electrode is formed over the color filter and the first blocking layer. Thus, an amount of a color filter pigment required for manufacturing the substrate may be decreased and manufacturing cost may be decreased.
