Abstract

A display apparatus includes: an emission layer including a light-emitting element which generates and emits light; a driving layer which drives the light-emitting element of the emission layer to generate and emit the light; and an adhesive layer which connects the light-emitting element to the driving layer. The driving layer includes: a substrate; and a conductive layer on the substrate and connected to the light-emitting element of the emission layer by the adhesive layer. The emission layer includes: a bank layer on the conductive layer of the driving layer, and an opening in the bank layer which exposes a portion of the conductive layer of the driving layer. The adhesive layer is disposed between the exposed portion of the conductive layer and the light-emitting element, and extends therefrom to be disposed on inner surfaces of the bank layer at the opening.

Claims (41)

1. A display apparatus comprising:

an emission layer comprising a light-emitting element which generates and emits light;

a driving layer which drives the light-emitting element of the emission layer to generate and emit the light; and

an adhesive layer which connects the light-emitting element to the driving layer,

wherein

the driving layer comprises:

a substrate; and

a conductive layer on the substrate and connected to the light-emitting element of the emission layer by the adhesive layer,

the emission layer comprises:

a bank layer on the conductive layer of the driving layer, and

an opening in the bank layer which exposes a portion of the conductive layer to outside the bank layer, and

within the opening in the bank layer:

the light-emitting element is disposed between side surfaces of the bank layer, and

the adhesive layer is disposed between the portion of the conductive layer and the light-emitting element, the adhesive layer extending from between the portion of the conductive layer and the light-emitting element to be disposed along the side surfaces of the bank layer at the opening.

2. The display apparatus of claim 1 , wherein the adhesive layer comprises a metal material.

3. The display apparatus of claim 1 , wherein the adhesive layer comprises at least one of silver (Ag), magnesium (Mg), aluminum (Al) and copper (Cu).

4. The display apparatus of claim 1 , wherein the light-emitting element of the emission layer comprises an electrode pad electrically connected to the conductive layer of the driving layer.

5. The display apparatus of claim 1 , wherein the adhesive layer comprises a reflection material which reflects light.

6. A display apparatus comprising:

an emission layer comprising a light-emitting element which generates and emits light;

a driving layer which drives the light-emitting element of the emission layer to generate and emit the light; and

an adhesive layer which connects the light-emitting element to the driving layer,

wherein

the driving layer comprises:

a substrate; and

a conductive layer on the substrate and connected to the light-emitting element of the emission layer by the adhesive layer,

the emission layer comprises:

a bank layer on the conductive layer of the driving layer,

an opening in the bank layer which exposes a portion of the conductive layer to outside the bank layer and in which the light-emitting element is disposed, and

within the opening in the bank layer:

the light-emitting element disposed in the opening comprises a reflective layer on side surfaces of the light-emitting element, and

the adhesive layer is disposed between the portion of the conductive layer and the light-emitting element and is spaced apart from side surfaces of the bank layer at the opening.

7. The display apparatus of claim 6 , wherein the reflective layer comprises an insulating material.

8. The display apparatus of claim 6 , wherein the reflective layer comprises at least one of silicon (Si), zirconium (Zr), hafnium (Hf), titanium (Ti) and aluminum (Al).

9. The display apparatus of claim 6 , wherein the adhesive layer comprises a metal material.

10. The display apparatus of claim 6 , wherein the adhesive layer comprises at least one of silver (Ag), magnesium (Mg), aluminum (Al) and copper (Cu).

11. The display apparatus of claim 6 , wherein the light-emitting element of the emission layer comprises an electrode pad electrically connected to the conductive layer of the driving layer.

12. The display apparatus of claim 6 , further comprising a reflective member which reflects the light emitted from the light-emitting element,

wherein the reflective member is defined by:

the adhesive layer which is disposed between the portion of the conductive layer and the reflective layer on the light-emitting element and reflects light, and

the reflective layer on the side surfaces of the light-emitting element disposed in the opening of the bank layer.
