ACTIVE MATRIX SUBSTRATE AND DISPLAY DEVICE

摘要

An active matrix substrate (5) is provided with mounting terminals (DT3), draw-out lines (22) connecting mounting terminals (DT4) and data bus lines (D), a first common wire (47) connected in common to the plurality of data bus lines (D), and second thin-film transistors (second switching elements) (45) connected between the draw-out lines (22) and the first common wire (47). End portions of the data bus lines (D) to which the mounting terminals (DT3) are not connected are connected to second common wires (54) via third thin-film transistors (52).

1. An active matrix substrate, comprising:
a base member; a plurality of gate bus lines provided on the base member; a plurality of data bus lines provided in a layer different from a layer of the gate bus lines via an insulating film therebetween; a first switching element connected to the gate bus lines and the data bus lines; a mounting terminal for supplying a signal from a driver to the gate bus lines or the data bus lines; a plurality of draw-out lines connecting the mounting terminal and the gate bus lines or the data bus lines; a plurality of second switching elements that are each connected to a corresponding one of the plurality of draw-out lines; a first common wire connected in common to at least two of the plurality of second switching elements; a plurality of third switching elements connected to end portions of the gate bus lines or the data bus lines to which the mounting terminal is not connected; and a second common wire connected in common to at least two of the plurality of third switching elements.
