Abstract

A light-emitting device includes a light body having an internal electrode layer, and a conductive layer. The conductive layer has a first portion formed on the internal electrode layer and overlapping the light body in a first direction, and a second portion overlapping the light body in a second direction. The first direction is perpendicular to the second direction.

Claims (29)

1. A light-emitting device comprising:

a light body having an internal electrode layer;

a conductive layer having a first portion formed on the internal electrode layer and overlapping the light body in a first direction, and a second portion overlapping the light body in a second direction; and

a reflective layer overlapping the light body in the second direction;

wherein the first direction is perpendicular to the second direction, and the reflective layer has a surface flush with a surface of the second portion.

2. The light-emitting device of claim 1 , wherein the light-emitting device has a side surface with a portion constituted by a surface of the conductive layer.

3. The light-emitting device of claim 1 , wherein the conductive layer has a protrusion protruding away the light body to extend along the second direction.

4. The light-emitting device of claim 1 , wherein the conductive layer does not overlap the light body in a third direction.

5. The light-emitting device of claim 1 , wherein the conductive layer has two surfaces exposed to ambient environment.

6. The light-emitting device of claim 1 , wherein the conductive layer has three surfaces exposed to ambient environment.

7. The light-emitting device of claim 1 , further comprising a wavelength conversion layer enclosing the light body.

8. The light-emitting device of claim 1 , further comprising a wavelength conversion layer formed on the light body.

9. The light-emitting device of claim 8 , wherein the wavelength conversion layer has an area larger than that of the light body.

10. The light-emitting device of claim 1 , wherein the reflective layer enclosing the light body.

11. A backlight module comprising:

a board; and

a light-emitting device of claim 1 mounted on the board.

12. The backlight module of claim 11 , wherein the light-emitting device has a main light-emitting direction parallel to a surface of the board.

13. A light-emitting device comprising:

a light body having an internal electrode layer;

a conductive layer having a first portion formed on the internal electrode layer and overlapping the light body in a first direction, and a second portion overlapping the light body in a second direction; and

a reflective layer enclosing the conductive layer and exposing a portion of the conductive layer in a third direction,

wherein the first direction, the second direction, and the third direction are perpendicular to each other.

14. The light-emitting device of claim 13 , wherein the conductive layer is not exposed from the reflective layer in the first direction and the second direction.

15. The light-emitting device of claim 13 , wherein the conductive layer does not overlap the light body in the third direction.

16. The light-emitting device of claim 13 , further comprising a wavelength conversion layer enclosing the light body.

17. The light-emitting device of claim 13 , further comprising a wavelength conversion layer formed on the light body.

18. The light-emitting device of claim 17 , wherein the wavelength conversion layer has an area larger than that of the light body.

19. The light-emitting device of claim 13 , wherein the reflective layer enclosing the light body.
