Abstract:
1. An active matrix substrate, comprising: a plurality of transistors arranged in a lattice pattern on a substrate; a plurality of gate lines extending in parallel to one another and connected to respective gates of the plurality of transistors; a plurality of source lines extending in parallel to one another so as to cross the plurality of gate lines and connected to respective sources of the plurality of transistors, the source lines being in communication with at least one video line; a gate line driving circuit for sending a scanning signal to the plurality of gate lines; a plurality of storage capacitors connected respectively to the plurality of transistors and to a common power supply; a source line driving circuit for successively selecting the plurality of source lines so as to send video signal(s) from the at least one video line to the storage capacitors via the source lines being selected; and a read-out line for reading out charges stored in the plurality of storage capacitors via respective ones of the plurality of source lines, wherein: the read-out line is a single line shared by the plurality of source lines; wherein the active matrix substrate further comprises:
