Abstract

Disclosed is a display panel (40a) comprising: a plurality of display wirings (3) that extend in mutually parallel fashion in each of blocks (B1 to B3) thereof; a plurality of drive circuits (44a) that are connected with each of the display wirings (3) in each of the blocks (B1 to B3) outside a display region (D); a plurality of first wirings (W1) that intersect in an insulated state the ends of each of the display wirings (3) within the blocks (B1 to B3) on the side of the drive circuits (44a), outside the display region (D); and second wirings (W2) that intersect in an insulated state the ends of each of the display wirings (3) within all of the blocks (B1 to B3) on the opposite side to the drive circuits (44a), outside the display region (D). The second wirings (W2) are constructed so as to intersect in an insulated state the first wirings (W1) and so that the display signal from the drive circuits (44a) is supplied through an amplification circuit (A).

Description

technical field [0001] The present invention relates to a display device, a method for manufacturing the same, and an active matrix substrate, and particularly relates to a technique for correcting disconnection of display wiring disposed on the active matrix substrate and the display device. Background technique [0002] A liquid crystal display device includes, for example, an active matrix substrate and a counter substrate arranged to face each other. This active matrix substrate includes, for example, a plurality of gate lines extending parallel to each other and a plurality of source lines extending parallel to each other in a direction perpendicular to each gate line as display wiring. Therefore, in the liquid crystal display device including this active matrix substrate, there is a problem that when a disconnection occurs in the display wiring of the gate line and the source line, in the disconnected display wiring, Since the signal for display from the drive circuit...
