Illumination device and method for manufacturing same

A method for manufacturing an illumination device, comprising:

• forming an anode, an organic electroluminescent unit, and a cathode on a substrate in the order of the anode, the organic electroluminescent unit, and the cathode;
• placing a metal layer having a plurality of first holes on the cathode via a first insulating layer;
• making a plurality of second holes to pierce the organic electroluminescent unit, the cathode, and the first insulating layer by using the plurality of first holes as a mask;
• filling an insulating material into the plurality of second holes;
• making a third hole in the insulating material to reach the anode;
• and
• electrically connecting the metal layer to the anode by filling a conductive material into the third hole.

A method for manufacturing an illumination device, comprising:

• forming an anode, an organic electroluminescent unit, and a cathode on a substrate in the order of the anode, the organic electroluminescent unit, and the cathode;
• making a plurality of fourth holes to pierce the organic electroluminescent unit and the cathode;
• and
• fitting a plurality of conductive protrusions formed on a major surface of a metal layer into the fourth holes and fixing the metal layer to the cathode via an insulating layer formed on the major surface of the metal layer, the fixing being performed in a state in which the insulating layer opposes the cathode and the anode is electrically connected to the plurality of protrusions and the metal layer.
