Abstract

A display device includes a first base on which a display area and a non-display area are defined; a first support member disposed on the first base and located in the non-display area; a light emitting element disposed on the first base and located in the display area; an encapsulation layer which disposed on the light emitting element; a second base disposed on the encapsulation layer; a color filter disposed between the second base and the encapsulation layer, where the color filter overlaps the light emitting element; a wavelength conversion pattern disposed on the color filter; and a sealing member disposed between the first base and the second base and located in the non-display area, where the sealing member is located between the display area and the first support member and overlaps the encapsulation layer.

Claims (32)

1 . A display device defining a thickness direction and comprising:

a first base on which a display area and a non-display area are defined;

a first support member disposed on the first base and located in the non-display area;

a light emitting element disposed on the first base and located in the display area;

an encapsulation layer disposed on the light emitting element;

a second base disposed on the encapsulation layer;

a color filter disposed between the second base and the encapsulation layer, wherein the color filter overlaps the light emitting element;

a wavelength conversion pattern disposed on the color filter; and

a sealing member disposed between the first base and the second base and located in only the non-display area, such that the encapsulation layer is disposed above the light emitting element and disposed under the sealing member relative to the first base,

wherein the sealing member comprises:

a first portion having an inner side facing the encapsulation layer in a first direction orthogonal to the thickness direction and an outer side opposite the inner side that is spaced apart from an edge of the first base, and

a second portion having an inner side facing the encapsulation layer in a second direction orthogonal to both the thickness direction and the first direction and an outer side opposite the inner side that is aligned in the thickness direction with the edge of the first base, and

wherein the first portion of the sealing member extends in a same direction as the first support member, is located between the first support member and the display area, overlaps the light emitting element in the first direction, and is spaced apart from the first support member.

2 . The display device of claim 1 , wherein a width of the first portion of the sealing member is greater than a width of the second portion of the sealing member.

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

a connection pad disposed on the first base and located in the non-display area,

wherein the first portion of the sealing member is located between the connection pad and the display area, and

the first support member is located between the connection pad and the first portion of the sealing member.

4 . The display device of claim 3 , further comprising:

a second support member disposed on the first base, located between the first support member and the connection pad, and spaced apart from the first support member,

wherein the second support member extends in a same direction as the first support member.

5 . The display device of claim 1 , wherein

the encapsulation layer comprises a lower inorganic layer disposed on the light emitting element, an organic layer disposed on the lower inorganic layer and an upper inorganic layer disposed on the organic layer, and

the sealing member is disposed on the upper inorganic layer in the non-display area and overlaps the lower inorganic layer and the upper inorganic layer.

6 . The display device of claim 1 , wherein

a portion of an outermost edge of the encapsulation layer is disposed between the first support member and the sealing member, and

the portion of the outermost edge of the encapsulation layer does not overlap the sealing member.

7 . The display device of claim 1 , wherein the first direction is orthogonal to the second direction.

8 . The display device of claim 1 , wherein the first support member and the sealing member do not overlap in the thickness direction of the display device.

9 . The display device of claim 1 , wherein the first support member and the sealing member overlap in a direction orthogonal to the thickness direction of the display device.

10 . The display device of claim 1 , wherein the first support member is located entirely in the non-display area.

11 . An electronic device comprising the display device of claim 1 .
