Light-emitting device and manufacturing method thereof

A method for manufacturing a light-emitting device, comprising the steps of:

• forming a first electrode layer over a first substrate;
• forming an insulating layer over the first electrode layer;
• forming a conductive connection electrode layer comprising an uneven shape over the insulating layer;
• forming a layer containing a light-emitting organic compound over the first electrode layer and the conductive connection electrode layer so that the conductive connection electrode layer is partially exposed through the layer over the conductive connection electrode layer;
• forming a second electrode layer over the layer containing the light-emitting organic compound;
• preparing a second substrate provided with a structure;
• and
• bonding the second substrate to the first substrate so that the second electrode layer is interposed between the conductive connection electrode layer and the structure,
• wherein the second electrode layer is electrically connected to the conductive connection electrode layer by the structure to press the second electrode layer over the conductive connection electrode layer.
