Problems solved by technology

Therefore, in the liquid crystal display device including this active matrix substrate, when the display wiring of the gate line or the source line is disconnected, the display wiring from the driving circuit will be disconnected from the display wiring where the disconnection occurs. The signal cannot be supplied further from the broken line, so there is a problem that the display quality is significantly lowered

Abstract

A display device is provided with: a display panel (40a) provided with a plurality of display wiring lines (3) extending in parallel to each other; a drive circuit (44a), which is provided on one end section of each display wiring line (3) and is connected to each display wiring line (3); a first wiring line path (Wa) and a second wiring line path (Wb) arranged to intersect with each other in theinsulated state on the end section of each display wiring line (3); and a third wiring line path (Wc), which intersects with the other end section of each display wiring line (3) in the insulated state and is connected to the first wiring line path (Wa) and the second wiring line path (Wb). An amplifying circuit (A) is arranged in a path which includes the first wiring line path (Wa) and the second wiring line path (Wb), and in a path which includes the first wiring line path (Wa) and the third wiring line path (Wc).

Description

technical field [0001] The present invention relates to a display device, a method of manufacturing the same, and an active matrix substrate, and in particular, to a technology 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 an opposing 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 a display configuration. Wire. Therefore, in the liquid crystal display device including this active matrix substrate, when the display wiring of the gate line or the source line is disconnected, the display wiring from the driving circuit will be disconnected from the display wiring where the disconnectio...
