Abstract

A display panel includes pixel electrodes disposed in a display region, position detection electrodes constituting a common electrode, a source line, position detection lines disposed in a layer identical to a layer of the source line and each connected to one of the position detection electrodes, a first position detection lead-out line disposed in a layer identical to a layer of the source line in a non-display region and extending from one end of one of the position detection lines, and a second position detection lead-out line disposed in a layer different from a layer of the source line in the non-display region and extending from one end of another of the position detection lines, the second position detection lead-out line extending overlapping the first position detection lead-out line.

Claims (24)

1. A display panel comprising:

a substrate divided into a display region configured to enable an image to be displayed and a non-display region surrounding the display region;

a plurality of pixel electrodes disposed in the display region;

a plurality of position detection electrodes disposed in the display region and configured to detect an input position by a position input body, the plurality of position detection electrodes constituting a common electrode disposed overlapping the plurality of pixel electrodes;

a pixel line disposed in the display region and connected to pixel electrodes of the plurality of pixel electrodes;

a plurality of position detection lines disposed in a layer identical to a layer of the pixel line in the display region and each connected to a position detection electrode of the plurality of position detection electrodes;

a pixel lead-out line disposed in the non-display region and extending from one end of the pixel line;

a first position detection lead-out line disposed in a layer identical to a layer of the pixel line in the non-display region and extending from one end of a position detection line of the plurality of position detection lines; and

a second position detection lead-out line disposed in a layer different from a layer of the pixel line in the non-display region and extending from one end of a position detection line of the plurality of position detection lines different from the position detection line from which the first position detection lead-out line extends, the second position detection lead-out line extending overlapping the first position detection lead-out line.

2. The display panel according to claim 1 further comprising:

a counter substrate spaced from and facing the substrate; and

a sealing member interposed between the substrate and the counter substrate and surrounding a space between the substrate and the counter substrate,

wherein the sealing member is formed from a photo-curable resin material, and

a portion of the sealing member is disposed overlapping the first position detection lead-out line and the second position detection lead-out line.

3. The display panel according to claim 1 ,

wherein a first pixel lead-out line of two of the pixel lead-out lines that are adjacent to each other is disposed in a layer identical to a layer of the pixel line, and

a second pixel lead-out line of two of the pixel lead-out lines is disposed in a layer identical to a layer of the second position detection lead-out line and extends overlapping the first pixel lead-out line.

4. The display panel according to claim 1 ,

wherein the first position detection lead-out line and the second position detection lead-out line are electrically connected to a position detection electrode of the plurality of position detection electrodes, and

the first position detection lead-out line and the second position detection lead-out line are electrically connected to each other at at least two locations.

5. The display panel according to claiml,

wherein a position detection line of the plurality of position detection lines and the second position detection lead-out line are electrically connected to each other via a conductive film, the conductive film being formed from a material identical to a material of the plurality of position detection electrodes.

6. The display panel according to claim 4 ,

wherein the first position detection lead-out line and the second position detection lead-out line are electrically connected to each other via a conductive film, the conductive film being formed from a material identical to a material of the plurality of position detection electrodes.
