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 in the direction intersecting the gate lines, and arranged along the direction intersecting the gate lines to be alternately offset from each other in a direction in which the gate lines extend, a plurality of second linear portions each extending along the gate lines and linking ends of adjoining ones of the first linear portions to each other, each of the plurality of second linear portions respectively including a protruding portion each extending from one end of the corresponding one of the second linear portions along the gate lines, the protruding portions being oriented in a same direction, 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.
