Abstract

A light emitting device includes: a substrate; a first electrode on the substrate; a metal member on the first electrode and having a cavity; a first insulating layer on the metal member and exposing the cavity therethrough; a bar-type LED having a first end portion and a second end portion; and a second electrode on the first insulating layer. The first end portion of the bar-type LED is in the cavity and electrically connected to the first electrode, and the second end portion of the bar-type LED protrudes outside of the cavity and is electrically connected to the second electrode.

Claims (24)

1. A light emitting device comprising:

a substrate;

a first conductive line on the substrate;

a second conductive line on the substrate and spaced apart from the first conductive line;

a metal member between the first conductive line and the second conductive line, the metal member having an opening; and

a light emitting element having a first end portion and a second end portion, the first end portion being in the opening, the second end portion protruding outside of the opening.

2. The light emitting device of claim 1 , wherein a part of the light emitting element overlaps the metal member in a direction normal to a surface of the substrate.

3. The light emitting device of claim 2 , wherein the light emitting element is oriented at an inclined angle with respect to the surface of the substrate.

4. The light emitting device of claim 3 , wherein the inclined angle of the light emitting element is greater than 0 degrees and less than 90 degrees.

5. The light emitting device of claim 2 , wherein a width of an inside portion of the opening is greater than a width of the opening at a top surface of the metal member.

6. The light emitting device of claim 2 , wherein a width of the opening at a top surface of the metal member is smaller than a width of the opening at a central portion of the metal member.

7. The light emitting device of claim 1 , further comprising:

a first electrode between the substrate and the metal member;

a first insulating layer on the metal member, the first insulating layer exposing the opening therethrough; and

a second electrode on the first insulating layer, the second electrode being connected to the second end portion of the light emitting element.

8. The light emitting device of claim 7 , wherein the opening in the metal member exposes at least a portion of the first electrode.

9. The light emitting device of claim 7 , further comprising:

a connecting member between the first end portion of the light emitting element in the opening and the first electrode.

10. The light emitting device of claim 7 , further comprising:

a second insulating layer between the first insulating layer and the second electrode,

wherein the second insulating layer has a contact opening at where the second end portion of the light emitting element and the second electrode are electrically connected to each other.

11. The light emitting device of claim 1 , further comprising:

a plurality of light emitting elements in the opening,

wherein at least one of the light emitting elements comprises a portion protruding outside the opening.
