Abstract:
A liquid crystal display device comprising:(A) a first substrate including a plurality of scanning lines and a plurality of signal lines arranged in a matrix form; a common signal line extended in parallel to one of said scanning lines and one of said signal lines, for applying a reference potential thereto; a pixel electrode; and a thin-film transistor having a source electrode connected to said pixel electrode, a drain electrode connected to said one of said signal lines, and a gate electrode connected to said one of said scanning lines, said thin-film transistor being formed in an intersection portion between said one of said scanning lines and said one of said signal lines;(B) a second substrate including a black matrix layer and positioned opposite to said first substrate thereby sandwiching a liquid crystal layer between said first substrate and said second substrate; and(C) an insulating layer sandwiched between said pixel electrode of the first substrate and said one of said scanning lines; wherein:while a voltage is applied between said common signal line and said pixel electrode to thereby produce an electric field, a direction of a molecular axis of liquid crystal molecules contained in said liquid crystal layer is rotated within a plane located parallel to said first substrate so as to performer a liquid crystal display; and further whereinsaid pixel electrode of said first substrate covers a total width of a portion of at least one of the scanning lines, andsaid pixel electrode of said first substrate further covers a second portion of said at least one of the scanning lines, said second portion being located within a thin-film transistor forming region, while sandwiching the insulating layer between said at least one of the scanning lines and said pixel electrode.
