Display device
According to one embodiment, a display device includes a base, a wiring layer disposed on the base, and in which a plurality of wiring lines are disposed, a display element disposed on the wiring layer and including an organic layer and a metal wiring line disposed to surround the display element, and the wiring layer includes a first portion in which wiring lines are densely arranged and a second portion in which wiring lines are sparsely arranged, and a width of a portion of the metal wiring line, which is disposed on a side of the second portion is greater than a width of a portion of the metal wiring line, disposed on a side of the first portion.
1. A display device comprising:
a base;
a wiring layer disposed on the base, and in which a plurality of wiring lines are disposed;
a display element disposed on the wiring layer and including an organic layer;
a metal wiring line disposed to surround the display element, and
an insulating layer disposed between the wiring layer and the display element to cover the wiring lines, wherein
the wiring layer includes a first portion in which wiring lines are densely arranged and a second portion in which wiring lines are sparsely arranged,
a width of a portion of the metal wiring line, which is disposed on a side of the second portion is greater than a width of a portion of the metal wiring line, disposed on a side of the first portion,
the insulating layer includes a portion covering the first portion and a portion covering the second portion, which have thicknesses different from each other,
the thickness of the portion of the insulating layer, which covers the first portion, is greater than the thickness of the portion which covers the second portion,
a surface of the insulating layer is inclined in a downward direction from the portion which covers the first portion to the portion which covers the second portion,
an emitting surface of the display element is inclined, similarly to the surface of the insulating layer, in a downward direction from a region overlapping the first portion to a region overlapping the second portion in plan view,
the display element includes a lower electrode and an upper electrode disposed to sandwich the organic layer therebetween, and
the metal wiring is disposed on a same layer as that of the organic layer and is in contact with the upper electrode.
2. The display device of claim 1 , wherein
the metal wiring line is formed of a low-resistance metal material.
