Patent ID: 8264630

Claim:
An active matrix substrate, comprising: a plurality of pixel regions defined in a matrix form; a plurality of source lines provided to extend in parallel to one another between the pixel regions; a plurality of gate lines provided to extend in parallel to one another in directions intersecting the source lines; a plurality of auxiliary capacitance lines provided to each extend between the gate lines; a plurality of thin film transistors each having a gate electrode electrically connected to one of the gate lines, a semiconductor layer provided to overlap the gate electrode, a source electrode provided to overlap the gate electrode and the semiconductor layer, the source electrode being electrically connected to one of the source lines, and a drain electrode provided to cross an end of the gate electrode so as to overlap the gate electrode and the semiconductor layer; and a plurality of auxiliary capacitance electrodes provided in the corresponding pixel regions to extend along the auxiliary capacitance lines and to overlap the auxiliary capacitance lines, in a same layer as the drain electrode of each of the thin film transistors, wherein in each of the auxiliary capacitance electrodes of the pixel regions, a side end on one side is disposed inside of one of the auxiliary capacitance lines, the side end on one side being in a direction in which the drain electrode crosses the end of the gate electrode so as to enter from outside of the gate electrode to inside thereof, and a side end on another side is disposed outside of the one of the auxiliary capacitance lines, the side end on another side being in a direction in which the drain electrode crosses the end of the gate electrode so as to go out from the inside of the gate electrode to the outside thereof.
