1. An active matrix substrate comprising:

  • a plurality of bus lines provided in a pixel region;

    a plurality of signal terminals for inputting a driving signal to each of the bus lines, the signal terminals being provided in a connection terminal region situated outside the pixel region;

    connection lines for connecting the signal terminals to the bus lines;

    additional signal terminals for inputting a signal to the bus lines through different paths from those used in inputting the driving signal from the signal terminals, the additional signal terminals being provided outside the pixel region;

    additional connection lines for connecting the bus lines to the additional signal terminals; and

    a plurality of switching elements for controlling connections between the bus lines and the additional connection lines,wherein the switching elements are divided into a plurality of groups, and can control connections between the bus lines and the additional connection lines on a group basis, andconnection elements that each comprise a diode or a switching element and connect the signal terminals to each other are provided in the connection terminal region.
