Abstract
Disclosed is a light emitting display device including a substrate, an auxiliary power electrode located on the substrate, a first protection layer located on the auxiliary power electrode, a second protection layer located between the first protection layer and the auxiliary power electrode, a contact portion configured to expose a part of the auxiliary power electrode through the first protection layer and the second protection layer, an eaves structure portion located at the contact portion, and a cover metal pattern located on the eaves structure portion.
Claims20
A light emitting display device comprising:
- a substrate;
- an auxiliary power electrode on the substrate;
- a first protection layer on the auxiliary power electrode;
- a second protection layer between the first protection layer and the auxiliary power electrode;
- a contact portion to expose a part of the auxiliary power electrode through the first protection layer and the second protection layer;
- an eaves structure portion located at the contact portion;
- and
- a cover metal pattern located on the eaves structure portion.
A light emitting display device comprising:
- a substrate comprising an active area in which subpixels are located and a non-active area adjacent to the active area;
- an auxiliary power electrode located between the subpixels;
- and
- an undercut structure located on the auxiliary power electrode, wherein the undercut structure comprises:
- a top portion;
- a lower portion to support the top portion;
- and
- a cover metal pattern to cover an entire upper surface of the top portion.
A method of manufacturing a light emitting display device, the method comprising:
- forming an auxiliary power electrode on a substrate;
- forming a passivation material layer on the auxiliary power electrode;
- forming a first pattern and an overcoat layer on the passivation material layer;
- forming a cover metal material layer on the first pattern and the overcoat layer;
- patterning the cover metal material layer;
- and
- removing the passivation material layer under the patterned cover metal material layer to form an undercut area.
