Optical device e.g. organic LED, has insulator that is arranged on bottom electrode layer at side of functional layer stack such that top electrode layer is formed on insulator and functional layer stack

摘要

#CMT# #/CMT# The optical device (1) has a layer laminate (2) having bottom and top electrode layers (3,4) on a metallic layer (10) formed on a substrate (9). A stack (5) having functional layers (6-8) is arranged between the electrode layers. An insulator (13) consisting of an electrically non-conductive material is arranged on the bottom electrode layer at the side of the functional layer stack such that the top electrode layer is formed on the insulator and functional layer stack. #CMT# : #/CMT# Independent claims are included for the following: (1) method for manufacturing of optical device; and (2) semi-finished product used during manufacturing of optical device. #CMT#USE : #/CMT# Optical device such as organic LED. #CMT#ADVANTAGE : #/CMT# Since insulator is arranged on bottom electrode layer at side of functional layer stack such that top electrode layer is formed on insulator and functional layer stack, the short circuit between top and bottom electrode layers and damage of the organic LED can be prevented so that the service lifetime of the organic LED can be extended. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a perspective view of the optical device. 1 : Optical device 2 : Layer laminate 3,4 : Electrode layers 5 : Functional layer stack 6-8 : Functional layers 9 : Substrate 10 : Metallic layer 13 : Insulator #CMT#INORGANIC CHEMISTRY : #/CMT# The electrode layer is formed from indium tin oxide, aluminium zinc oxide, silver, aluminium and/or of another metal and/or an alloy with calcium, barium, ruthenium or magnesium silver alloy. The functional layer (7) is formed from tris(8-hydroxyquinolinato)aluminum.
