Abstract

An electroluminescence apparatus includes: a plurality of electroluminescence elements each of which includes a first electrode, a second electrode that is provided opposite the first electrode, and a light-emitting function layer that is sandwiched between the first electrode and the second electrode and includes at least an electroluminescence material layer, the electroluminescence element emitting light produced in the electroluminescence material layer through the second electrode; a separation area; a display area and auxiliary wiring being electrically connected to the second electrode, the auxiliary wiring including first auxiliary wiring and second auxiliary wiring, wherein the first auxiliary wiring extends in the first direction without any break, and the second auxiliary wiring has a gap that is formed between the first auxiliary wiring and the second auxiliary wiring.

Claims (17)

1. An electroluminescence apparatus comprising:

a plurality of electroluminescence elements each of which includes a first electrode, a second electrode that is provided opposite the first electrode, and a light-emitting function layer that is disposed between the first electrode and the second electrode;

a separation area that separates the plurality of electroluminescence elements arranged next to one another;

a display area in which the plurality of electroluminescence elements and the separation area are formed; and

a plurality of auxiliary wirings that are formed in the separation area, the auxiliary wirings being electrically connected to the second electrode, the auxiliary wirings including a first auxiliary wiring that extends in a first direction and a second auxiliary wiring that extends in a second direction, which is different from the first direction,

wherein the first auxiliary wiring and the second auxiliary wiring are disposed in a first layer, the second auxiliary wiring not contacting the first auxiliary wiring and separated from the first auxiliary wiring, and

wherein a gap is positioned between the first auxiliary wiring and the second auxiliary wiring, the gap includes a first gap and a second gap formed in the display area, and a dimension of the first gap is different from a dimension of the second gap.

2. The electroluminescence apparatus according to claim 1 , wherein the first direction and the second direction is orthogonal, or substantially orthogonal, to each other.

3. An electronic apparatus that is provided with the electroluminescence apparatus according to claim 1 .

4. An electroluminescence apparatus comprising:

a substrate;

a plurality of electroluminescence elements that are disposed above the substrate, each of the electroluminescence elements includes a first electrode, a second electrode opposed to the first electrode, and a light-emitting layer disposed between the first electrode and the second electrode; and

a plurality of auxiliary wirings that are electrically connected to the second electrode, the auxiliary wirings having a first auxiliary wiring extending in a first direction and a second auxiliary wiring extending in a second direction intersecting the first direction,

the electroluminescence elements include a first group of the electroluminescence elements having a first electroluminescence element, a second electroluminescence element, and a third electroluminescence element and a second group of the electroluminescence elements having a fourth electroluminescence element, a fifth electroluminescence element, and a sixth electroluminescence element, the first group of the electroluminescence elements and the second group of the electroluminescence elements extending in the first direction,

the first auxiliary wiring extending along at least one of the first group of the electroluminescence elements and the second group of the electroluminescence elements, and

the second auxiliary wiring disposed in an area positioned between the first group of the electroluminescence elements and the second group the electroluminescence elements, and

wherein a gap is positioned between the first auxiliary wiring and the second auxiliary wiring, the gap includes a first gap and a second gap, and a dimension of the first gap is different from a dimension of the second gap.
