Abstract
There is disclosed an active matrix liquid crystal display apparatus in which a data signal line is disposed apart from a pixel electrode, a gate insulating film is disposed between the data signal line and an extending portion of an auxiliary capacity line, the extending portion is superposed upon a peripheral portion of the pixel electrode, and a parasitic capacity Cds between the pixel electrode and the data signal line is reduced.

An active matrix liquid crystal display apparatus comprising:
- a substrate;
- a plurality of pixel electrodes formed on said substrate;
- a plurality of switching elements electrically connected to said pixel electrodes, respectively;
- a plurality of data signal lines connected to said switching elements;
- a first insulating layer disposed between said data signal lines and said pixel electrodes;
- an auxiliary capacity line partially overlapping with each pixel electrode;
- and
- a second insulating layer disposed between said data signal lines and said auxiliary capacity lines, each auxiliary capacity line having a portion overlapping with said data signal line, the portion having a width larger than a width of the data signal line disposed right above the auxiliary capacity line, and overlapping with a peripheral edge of said pixel electrode.
