Title:
METHOD OF PRODUCING ORGANIC EL ELEMENTS, ORGANIC EL ELEMENTS AND ORGANIC EL DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/1998/024271
Kind Code:
A1
Abstract:
A methods of producing organic EL elements includes a step for forming pixel electrodes (801, 802 and 803) on a transparent substrate (804), and a step for pattern-forming light-emitting layers (806, 807, and 808) of an organic compound on the pixel electrodes relying on an ink-jet system. This makes it possible to easily effect the patterning within short periods of time while maintaining precision, to easily design the films, to optimize the light-emitting property, and to easily adjust the light-emitting efficiency.
