Abstract
In an auxiliary capacitance electrode of each pixel region, a side end on one side in a direction in which a drain electrode crosses an end of a gate electrode so as to enter from the outside of the gate electrode to the inside thereof is disposed inside of an auxiliary capacitance line, and a side end on the other side 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 is disposed outside of the auxiliary capacitance line.
Claims9
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.
