Patent ID: 7142274

Claim:
A liquid crystal display device, comprising: (a) a first substrate including a thin film transistor, a data line, a pixel electrode, and a common electrode; (b) a second substrate; and (c) liquid crystal sandwiched between said first and second substrates, wherein an image signal is applied to said thin film transistor through said data line to generate an electric field between said pixel electrode receiving said image signal and said common electrode such that said liquid crystal is rotated by said electric field in a plane which is in parallel with said first substrate, and said first substrate includes: an electrically insulating inorganic film covering said data line therewith; a first island-shaped electrically insulating organic film formed on said electrically insulating inorganic film above said data line; and a shield common electrode covering said first island-shaped electrically insulating organic film therewith and overlapping said data line when viewed vertically, wherein said first island-shaped electrically insulating organic film covers only said data line, a gate line and terminals therewith.
