Abstract:
1. A liquid crystal device comprising: a source line over a substrate; a gate line over said substrate extending across said source line; and a pixel over said substrate at an intersection of said source line and said gate line, said pixel comprising: at least first and second thin film transistors wherein a source or drain of said first thin film transistor is electrically connected to said source line; and a pixel electrode electrically connected to a source or drain of said second thin film transistor wherein said first and second thin film transistors are electrically connected in series between said pixel electrode and said source line; wherein a portion of said source line covers at least a channel region of said first thin film transistor while a channel region of said second thin film transistor is not covered by any portion of said source line, and wherein a width of said source line is larger than a width of said channel region of said first thin film transistor, said width of said channel region taken along a direction perpendicular to a current flow direction of said channel region.
