  • Liquid crystal display device
    Patent number: 8035781
    Abstract: With an object of providing a transflective type liquid crystal display device having a transparent electrode of an uneven structure formed without particularly increasing steps, in fabricating the transflective type liquid crystal display device, a amorphous transparent conductive film is formed on a substrate, a crystalline portion is formed in the amorphous transparent conductive film to thereby form the transparent conductive film including the crystalline portion, a amorphous portion is removed at a film surface of the transparent conductive film including the crystalline portion to thereby form the transparent conductive film having an uneven shape formed by a remaining crystalline portion at a film surface and a reflecting electrode having the uneven shape is formed by forming a reflective conductive film above the transparent electrode having the uneven shape.
    Type: Grant
    Filed: February 9, 2007
    Date of Patent: October 11, 2011
    Assignee: Semiconductor Energy Laboratory Co., Ltd.
    Inventors: Shingo Eguchi, Yuriko Tsuji
