MANUFACTURING METHOD OF AN ORGANIC ELECTROLUMINESCENCE DISPLAY DEVICE AND THE ORGANIC ELECTROLUMINESCENCE DISPLAY DEVICE
First Claim
1. A manufacturing method of an organic electroluminescence display device including a device substrate provided with a plurality of pixel electrodes which have a gap part therebetween, a common electrode disposed opposite to the plurality of pixel electrodes, a light emitting layer provided between the common electrode and the plurality of pixel electrodes, and a bank layer protruding from the pixel electrode in the gap part of the plurality of pixel electrodes, the method comprising:
- forming a cover layer including a concave region to fit into a convex shaped part of the bank layer at a support substrate;
forming a color filter layer from a region of the cover layer facing the pixel electrode to the concave region;
disposing a surface of the color filter layer of the support substrate on the device substrate so that the concave region fits into a convex shaped part; and
attaching the cover layer and the color filter layer on the device substrate by peeling the cover layer from the support substrate.
