Patent number: 7557899Abstract: A liquid crystal display device includes a first substrate including a thin film transistor, a data line, a pixel electrode, and a common electrode, a second substrate, and liquid crystal sandwiched between the first and second substrates, wherein an image signal is applied to the thin film transistor through the data line to generate an electric field between the pixel electrode receiving the image signal and the common electrode such that the liquid crystal is rotated by the electric field in a plane which is in parallel with the first substrate. The first substrate includes an electrically insulating inorganic film covering the data line therewith, a first island-shaped electrically insulating organic film formed on the electrically insulating inorganic film above the data line, and a shield common electrode covering the first island-shaped electrically insulating organic film therewith and overlapping the data line when viewed vertically.Type: GrantFiled: February 1, 2008Date of Patent: July 7, 2009Assignee: NEC LCD Technologies, LtdInventors: Yoshiro Kitagawa, Satoshi Kimura, Tsuyoshi Satoh, Hidenori Kusanagi, Juko Funaki, Sounosuke Takahashi, Takayuki Konno, Shinichi Nishida
