Patent ID: 7626333

Claim:
An organic electroluminescent device, comprising: a substrate; anode electrode layers disposed over the substrate in a first direction; cathode electrode layers disposed over or under the anode electrode layers in a second direction that is different from the first direction; organic material layers disposed between the anode electrode layers and the cathode electrode layers; at least one outer wall disposed at the periphery of an active area defined by an entire area of the organic material layers; a cap attached over the at least one outer wall, wherein a substrate-forward surface of the cap is flat; a driving chip attached to the substrate-forward surface of the cap; a signal transferring part configured to electrically communicate with the driving chip, and the signal transferring part to extend to an outside of an area defined by the substrate and the cap; a pad disposed over the substrate, and the pad configured to electrically communicate with the anode electrode layers and/or the cathode electrode layers and electrically bonded to the signal transferring part at the outside of the area; and an external signal transferring part configured to electrically communicate with the signal transferring part and to transfer an external signal to the driving chip, wherein the at least one outer wall is an insulating material.
