Abstract

An organic EL device includes a thin film transistor (TFT) array substrate including a first insulating substrate, a TFT formed on the first insulating substrate and a capacitor; and an organic EL substrate including a second insulating substrate, and a transparent electrode, an organic EL layer and a metal electrode, which are sequentially stacked on the second insulating substrate; wherein the TFT is electrically connected to the metal electrode.

Claims (8)

1. An organic EL device, comprising:

a thin film transistor (TFT) array substrate including a first insulating substrate, a TFT, a capacitor formed on the first insulating substrate, a conductive interface pad and a conductive bump pad formed on the conductive interface pad; and

an organic EL substrate including a second insulating substrate, a transparent electrode, an organic EL layer and a metal electrode, and a polymer bump,

wherein the conductive bump pad contacts a portion of the metal electrode corresponding to the polymer bump by a conductive bonding agent, and

wherein the TFT is electrically connected to the metal electrode.

2. The device of claim 1 , wherein the conductive bonding agent is an anisotropic conductive film (ACF).

3. The device of claim 2 , wherein the anisotropic conductive film prevents oxygen and moisture from permeating through the second insulating substrate.

4. The device of claim 1 , wherein the transparent electrode, the organic EL substrate and the metal electrode are sequentially stacked on the second insulating layer.
