  • Patent number: 10842734
    Abstract: Disclosed a Dahlia pinnata composition, Dahlia pinnata composition powders, a Dahlia pinnata cosmetic composition and a method for producing the same. A method for producing a Dahlia pinnata composition includes preparing Dahlia pinnata petals; adding and stirring ethanol into the Dahlia pinnata petals to extract Dahlia pinnata extract; filtering the Dahlia pinnata extract; and diluting the filtered Dahlia pinnata extract in a solvent to obtain a Dahlia pinnata composition having an antioxidant efficacy. The Dahlia pinnata composition is produced by the method for producing a Dahlia pinnata composition, and thus has an antioxidant efficacy. In addition, the cosmetic composition includes the Dahlia pinnata extract and thus has an antioxidant efficacy.

  • Patent number: 8367301
    Abstract: A mask for crystallizing silicon includes a first, a second, and a third pattern part arranged in a longitudinal direction, each of the first, second, and third pattern parts including a plurality of unit blocks for transmitting and blocking a portion of light. At least two of the first, second and third pattern parts have a corresponding pattern to each other. Advantageously, scans using the aforementioned mask effectively remove a boundary on the silicon formed by the difference in the amount of laser beam irradiation received by the silicon, thereby improving electronic characteristics of the silicon.

  • Patent number: 7573552
    Abstract: A transflective liquid crystal display device has improved light efficiency. A method of fabricating a transflective liquid crystal display device including a thin film transistor substrate having a transmissive region and a reflective region, includes forming a retardation layer on a lower surface of the thin film transistor substrate, aligning a mask having a reflective region pattern on the lower surface of the thin film transistor substrate, and forming a light efficiency enhancer by selectively removing the retardation layer by irradiating a laser onto the lower surface of the thin film transistor substrate through the mask.
