Abstract:
1. An active matrix type display device, comprising: an image display region; a peripheral region which surrounds the image display region on an insulation substrate; a plurality of thin film transistors which are arranged in the image display region; a plurality of signal lines which supply signals to the thin film transistors; and connection pads which are arranged in the peripheral region and are connected with one ends of the signal lines, wherein the peripheral region of the insulation substrate includes short-circuiting lines which are arranged to face a first end portion of the substrate outside the connection pads and inter-pad short-circuiting lines which extend toward the first end portion of the insulation substrate from the connection pads, each of the inter-pad short-circuiting lines being connected with one of the short-circuiting lines, and a cut region which cuts electric connection between at least two of the plurality of inter-pad short-circuiting lines and at least two of the short-circuiting lines is arranged outside the connection pads and inside the short-circuiting lines and leaves electric connection between at least one of the inter-pad short-circuiting lines and at least one of the short-circuiting lines.
