Abstract:
A method of manufacturing an EL device comprising the steps of:forming a plurality of first electrode stripes extending longitudinally in one direction on a surface of a substrate;forming a plurality of insulating partition wall stripes on said first electrode stripes extending longitudinally in a direction perpendicular to said first electrode stripes;forming an organic layer comprising a hole transporting layer, a luminescence layer, and an electron transporting layer on said partition wall stripes, and forming a second electrode layer on said organic layer;adhering a sealing glass cap so as to cover said first electrode, said partition wall, said organic layer, and said second electrode, and evacuating the inside of said sealing glass cap; andirradiating a laser light from the outside of said sealing glass cap toward said partition wall for dividing said second electrode and said organic layer so as to form a divided groove on said partition wall.
