Abstract

According to one embodiment, a display device includes a first insulating member disposed surrounding a display area, a second insulating member disposed to be spaced apart from the first insulating member and surrounding the first insulating member, an auxiliary member disposed on the second insulating member and an sealing layer. The sealing layer includes a first inorganic sealing layer disposed in a region surrounded by the second insulating member, a first organic sealing layer disposed in a region surrounded by the first insulating member, a second inorganic sealing layer disposed in an region surrounded by the second insulating member and a second organic sealing layer which covers the second inorganic sealing layer.

Claims (34)

1 . A display device comprising:

a base;

a first insulating layer disposed on the base;

a display element disposed on the first insulating layer for each pixel provided in a display area;

a second insulating layer disposed on the first insulating layer and including an opening portion which overlaps the display element;

a first insulating member disposed in a peripheral area on an outer side of the display area and surrounding the display area;

a second insulating member disposed in the peripheral area so as to be spaced apart from the first insulating member and surrounding the first insulating member;

an auxiliary member disposed on the second insulating member; and

an sealing layer which covers the display element,

the sealing layer including:

a first inorganic sealing layer disposed in a region surrounded by the second insulating member;

a first organic sealing layer disposed on the first inorganic sealing layer in a region surrounded by the first insulating member;

a second inorganic sealing layer disposed in an region surrounded by the second insulating member and sealing the first organic sealing layer together with the first inorganic sealing layer; and

a second organic sealing layer which covers the second inorganic sealing layer in a region surrounded by the second insulating member.

2 . The display device of claim 1 , wherein

the first organic sealing layer is formed by being interrupted by the first insulating member, and

the second organic sealing layer is formed by being interrupted by the second insulating member and the auxiliary member.

3 . The display device of claim 2 , wherein

peripheral portions of the first and second inorganic sealing layers are removed using the second organic sealing layer as a mask.

4 . The display device of claim 1 , further comprising:

a partition disposed on the second insulating layer so as to divide pixels from each other,

wherein

the first and second insulating members are disposed in a same layer as that of the first and second insulating layers, and

the auxiliary members are disposed in a same layer as that of the partition.

5 . The display device of claim 4 , wherein

the auxiliary member is formed by a same process as that of the partition.

6 . The display device of claim 5 , wherein

the partition and the auxiliary member have a shape in which a width of an upper portion is greater than a width of a lower portion.

7 . The display device of claim 4 , wherein

the display element includes:

a first electrode disposed on a first insulating layer which overlaps the respective pixel;

an organic layer in contact with the first electrode via the opening portion; and

a second electrode disposed on the organic layer, and

the second electrode which overlaps a first pixel is connected to the second electrode which overlaps a second pixel adjacent to the first pixel via an auxiliary wiring line disposed between the second insulating layer and the partition.
