FIELD: physics, optics.
SUBSTANCE: invention relates to an active matrix substrate and a display device. The present invention discloses an active matrix substrate in which a peripheral region is provided outside the display region. On the active matrix substrate, first, second and third transistors, a floating connection, a switching connection, a basic connection and a branched connection which is electrically connected to the basic connection are situated in the peripheral region. Each of the floating connection and the branching connection is electrically connected to the first and second transistors and has an intersection area which crosses with the switching connection, wherein the third transistor is provided in the intersection area. The gate electrode of the third transistor includes a switching connection, one of its source and drain electrodes includes a branching connection and the other of said source and drain electrodes includes a floating connection.
EFFECT: high output of non-defective products by narrowing the screen frame and increasing the distance between neighbouring connections.
