Abstract:
The active matrix liquid crystal display unit comprising:a first substrate structure including:at least two non-transparent gate lines spaced from each other,an insulating layer covering said at least two gate lines,at least one data line electrically isolated from said at least two gate lines,a transparent pixel electrode electrically isolated from said at least two gate lines by means of said insulating layer, said pixel electrode being connectable to said at least one data line, and having an end portion which overlaps a part of one of said two gates lines as a capacitive gate line, to form an accumulating capacitor together with said insulating layer and said capacitive gate line, said end portion which overlaps with said capacitive gate line having a width varied along said capacitive gate line, wherein said capacitive gate line has a longitudinal edge which overlaps said pixel electrode to define a virtual line,a switching transistor connected between said at least one data line and said transparent pixel electrode and gated by the other of said at least two gate lines, anda first transparent orientation layer covering at least said transparent pixel electrode and having first rubbing lines directed to a first direction;a second substrate structure including:a transparent counter electrode opposed to said transparent pixel electrode, anda second transparent orientation layer covering at least said counter electrode and having second rubbing lines directed to a second direction different from said first direction; anda liquid crystal layer disposed between said first substrate structure and said second substrate structure,wherein said pixel electrode has a non-uniform edge including a first sub-end line and a second sub-end line which overlaps the capacitive gate line such that said width of said end portion of said pixel electrode is changed so as to have a wide sub-portion and a narrow sub-portion wherein said wide sub-portion and said narrow sub-portion are connected by a sloped connecting region with a continually decreasing width,said wide sub-portion having a width defined by said first sub-end line of said pixel electrode, and the virtual line,said narrow sub-portion having a width defined by said second sub-end line and the virtual line.
