Title: DISPLAY DEVICE
Abstract:
According to the present invention, short circuiting of two connection lines to which the same signal is inputted is suppressed in an active matrix substrate. The active matrix substrate is provided with: first wirings each formed in a first wiring layer; second wirings each formed in a second wiring layer; third wirings that are each formed in a third wiring layer and to which a signal different from signals supplied to the first wirings and the second wirings is supplied; first connection lines that connect the first wirings or the second wirings to a first terminal; second connection lines that connect the third wirings to a second terminal; inspection TFTs (switching elements for the second connection lines) 61 connected to the second connection lines; and two or more common wirings 63 and 64 which are each connected to one of the inspection TFTs 61. The second connection lines 24c are connected to one of the common wirings via the inspection TFTs 61. Among pairs of the second connection lines 24c that are adjacent to each other, a pair of the connection lines 24c that are connected to an identical common wiring have a smaller interval therebetween than a pair of the connection lines 24c that are connected to different common wirings.
