DISPLAY DEVICE
According to one embodiment, a display device includes a plurality of display elements each including a lower electrode, an upper electrode, and an organic layer between the lower electrode and the upper electrode, a partition which includes a conductive lower portion and an upper portion protruding from a side surface of the lower portion and surrounds each of the display elements, and a touch panel electrode which detects an object contacting or approaching a display area including the display elements. The touch panel electrode includes a first metal line located above the partition and extending along the partition.
1 . A display device comprising:
a plurality of display elements each including a lower electrode, an upper electrode which faces the lower electrode, and an organic layer which is provided between the lower electrode and the upper electrode and emits light based on a potential difference between the lower electrode and the upper electrode;
a partition which includes a conductive lower portion and an upper portion protruding from a side surface of the lower portion and surrounds each of the display elements; and
a touch panel electrode which detects an object contacting or approaching a display area including the display elements, wherein
the touch panel electrode includes a first metal line located above the partition and extending along the partition.
2 . The display device of claim 1 , further comprising a rib which comprises a plurality of pixel apertures overlapping the display elements, respectively, wherein
the partition is provided on the rib, and
a width of the first metal line is less than or equal to a width of the rib between the two adjacent pixel apertures.
3 . The display device of claim 1 , wherein
a width of the first metal line is less than or equal to a width of the upper portion.
4 . The display device of claim 1 , further comprising:
a plurality of first sealing layers which cover the display elements, respectively;
a resin layer which covers the first sealing layers; and
a second sealing layer which covers the resin layer, wherein
the first metal line is provided on the second sealing layer.
5 . The display device of claim 4 , further comprising:
a cover member which faces the second sealing layer; and
an adhesive layer which attaches the cover member to the second sealing layer, wherein
the first meal line is covered with the adhesive layer.
6 . The display device of claim 4 , further comprising a third sealing layer which covers the first metal line, wherein
each of the second sealing layer and the third sealing layer is formed of an inorganic insulating material.
7 . The display device of claim 1 , further comprising:
a terminal portion provided in a surrounding area around the display area;
a lead provided in the surrounding area and connected to the terminal portion; and
a relay line which connects the touch panel electrode to the lead.
8 . The display device of claim 7 , wherein
the relay line includes a second metal line located above the partition and extending along the partition.
9 . The display device of claim 8 , further comprising:
a plurality of first sealing layers which cover the display elements, respectively;
a resin layer which covers the first sealing layers; and
a second sealing layer which covers the resin layer, wherein
the first metal line and the second metal line are provided on the second sealing layer.
10 . The display device of claim 8 , wherein
the second metal line is located in the display area and surrounds at least one of the display elements as seen in plan view.
11 . The display device of claim 7 , further comprising a dummy line which is provided in the surrounding area and extends parallel to the lead.
12 . The display device of claim 7 , further comprising:
an organic insulating layer located below the lead; and
an output line located below the organic insulating layer, wherein
the terminal portion comprises a conductive pad located below the organic insulating layer and connected to the output line, and
the lead and the output line are connected to each other through a contact hole which penetrates the organic insulating layer.
13 . The display device of claim 12 , further comprising:
an adhesive layer which covers the first metal line and the lead; and
a cover member which faces the first metal line and the lead via the adhesive layer, wherein
the lead located in the contact hole is exposed from the adhesive layer.
14 . The display device of claim 12 , wherein
the organic insulating layer comprises a slit located between the pad and the display area.
15 . The display device of claim 14 , wherein
the lead crosses the slit.
16 . The display device of claim 1 , wherein
the first metal line surrounds at least one of the display elements as seen in plan view.
