An active matrix substrate comprises a TFT (4) in which a plurality of drain electrodes (16a and 16b) are provided for a single source electrode (6), and at least one of the drain electrodes is electrically connected to the pixel electrode (1) via the drain outgoing wire. The drain outgoing wire includes a first conductive pattern section comprising (i) a drain outgoing wire common section (7d) and drain outgoing branch sections (7a and 7b) each of which extends from said drain outgoing common section into each of said drain electrodes, and (ii) a correction connection electrode 9 which is partially overlapped with said branch sections of said first conductive pattern section via an insulating layer. The correction connection electrode 9 is electrically connectable to a plurality of said branch sections by being conducted to said branch sections through said insulating layer. This structure allows pixel defect correction within the pixel.
An active matrix substrate including an active element having at least one source electrode, two or more drain electrodes, and two or more channels, at least one of said drain electrodes is electrically connected to a pixel electrode via a wire section, said wire section includes a first conductive pattern section having a common section continuous to a pixel electrode and branch sections each of which extends from said common section and is broken into each of said drain electrodes,
