Abstract

A display device includes a substrate having plural signal lines connected to switching elements which are formed in an image display region, and plural terminals connected to respective ones of the signal lines. The terminals include a first group arranged at an image display region side and a second group arranged remote from the image display region side, the terminals being connected to output terminals of a driving circuit. The output terminals include a first group arranged at the image display region side and a second group arranged remote from the image display region side. The first group of terminals connect the first group of output terminals, and the second group of terminals connect the second group of output terminals. An area of a respective output terminal of the second group is larger than an area of a respective output terminal of the first group.

Claims (12)

1. A display device including:

a substrate having plural signal lines connected to switching elements which are formed in an image display region, the plural signal lines extending in one direction and being arranged in parallel in a direction intersecting the one direction; and

plural terminals connected to respective ones of the signal lines;

wherein the terminals include a first group of terminals arranged at an image display region side and a second group of terminals arranged remote from the image display region side, the terminals being connected to output terminals of a driving circuit;

wherein the output terminals include a first group of output terminals arranged at the image display region side and a second group of output terminals arranged remote from the image display region side; and

wherein the first group of terminals connect the first group of output terminals, and the second group of terminals connect the second group of output terminals, an area of a respective output terminal of the second group being larger than an area of a respective output terminal of the first group.

2. A display device according to claim 1 , wherein the terminals of the first group and the terminals of the second group are arranged in a staggered manner; and

wherein the output terminals of the first group and the output terminals of the second group are arranged in staggered manner.

3. A display device according to claim 1 , wherein a width of the output terminals of the second group is set larger than a width of the output terminals of the first group.

4. A display device according to claim 1 , wherein a length of the output terminals of the second group is set larger than a length of the output terminals of the first group.

5. A display device according to claim 1 , wherein the driving circuit includes a scanning signal driving circuit.

6. A display device according to claim 1 , wherein the driving circuit includes a video signal driving circuit.
