Abstract
The present invention provides an active matrix substrate and a display device that have sufficient resistance to a surge current without formation of a short ring and that enable narrowing of a picture-frame region. The present invention is an active matrix substrate on which a plurality of pixels are formed in a matrix shape. The active matrix substrate includes, on one principal surface side of the substrate: a terminal; a semiconductor element; wiring that is formed in a picture-frame region of the substrate and that connects the terminal and the semiconductor element; and an annular conductive portion formed through an insulation layer on at least one of an upper layer side and a lower layer side of the wiring. The wiring comprises a meander structure including a meander-shaped portion. A portion of the conductive portion is disposed along the meander-shaped portion.
