ABSTRACT:
An active matrix substrate has an insulating substrate, a plurality of signal lines and a plurality of scanning lines arranged in a matrix on the insulating substrate and defining a matrix of areas, each area including a pixel electrode and a switching device. The switching device has a connecting electrode for connecting the switching device to the pixel electrode. The connecting electrode includes a rectangular main portion and an extended portion connected to the main portion, and the main portion has a side which is substantially identical in length to the width of the switching device. The main portion and the extended portion are disposed between the pixel electrode and the insulating substrate.
