Abstract

A plurality of source lines extending parallel to each other while alternately turning between a plurality of pixel electrodes provided in a delta arrangement, each have 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.

Claims

1. 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.

2. The active matrix substrate of claim 1, wherein

the protruding portions have the same length.

3. A liquid crystal display device comprising:

the active matrix substrate of claim 1;

a counter substrate facing the active matrix substrate; and

a liquid crystal layer provided between the active matrix substrate and the counter substrate.
