Patent ID: 8599121

Claim:
An active matrix substrate comprising: data signal lines each for one of data signals; scanning signal lines crossing with the data signal lines; a matrix of pixel circuits each corresponding to one of intersections made by the data signal lines and the scanning signal lines; wherein each pixel circuit includes: a field-effect transistor having: a source electrode connected with one of the data signal lines that passes through a corresponding one of the intersections, directly or via a predetermined switching element and/or a capacity element; and a gate electrode connected with one of the scanning signal lines that passes through the corresponding intersection; and a voltage holding electrode connected with a drain electrode of the field-effect transistor, providing a predetermined voltage holding capacitor; and wherein an electrostatic capacity Cgd between the gate electrode and the drain electrode in the field-effect transistor increases whereas a rate of the increase of the electrostatic capacity Cgd decreases with an increasing electrical distance from a location of signal application for driving the scanning signal line which passes through the corresponding intersection.
