Active matrix substrate and liquid crystal display device

An active matrix substrate comprising:

• a plurality of pixel electrodes provided in a delta arrangement;
• a plurality of gate lines extending parallel to each other in a straight line, each provided between the corresponding pixel electrodes;
• a plurality of source lines extending parallel to each other in a direction intersecting the gate lines while alternately turning, each provided between the corresponding pixel electrodes;
• and
• a plurality of thin film transistors connected to the respective pixel electrodes, wherein
• each of the source lines has a plurality of first linear portions each extending along a side of the corresponding pixel electrode, a plurality of second linear portions each linked to the corresponding first linear portion and extending along a side of the corresponding pixel electrode to a middle portion of the side, and a plurality of protruding portions each extending from one end of the corresponding second linear portion along a side of the corresponding pixel electrode, and
• each of the thin film transistors is alternately connected to the corresponding first or second linear portion and to the corresponding protruding portion along the corresponding source line.
