Organic electroluminescence display panel and method of manufacturing the same
First Claim
1. An organic electroluminescence display panel comprising:
- a plurality of organic electroluminescence elements each comprised of a first display electrode, one or more organic functional layers including a light emitting layer made of an organic compound, and a second display electrode, laminated in order on a substrate;
a plurality of ramparts disposed between said organic electroluminescence elements on said substrate and protruding from said substrate;
a sealing film for covering said organic electroluminescence elements and at least both side surfaces of said ramparts; and
an inorganic passivation film made of an inorganic material for covering said sealing film, wherein said sealing film includes a top surface having an inclined surface which is inclined at an inclination angle smaller than a right angle in a region extending from a top edge of each said rampart to a center peak of an adjacent one of said organic electroluminescence elements.

Abstract
An organic electroluminescence display panel includes a plurality of organic electroluminescence elements, each comprised of a first display electrode, one or more organic functional layers including a light emitting layer made of an organic compound, and a second display electrode, laminated in order on a substrate, and a plurality of ramparts disposed between the organic electroluminescence elements on the substrate and protruding from the substrate. The display panel further includes a sealing film for covering the organic electroluminescence elements and at least both side surfaces of the ramparts, and an inorganic passivation film made of an inorganic material for covering the sealing film. The sealing film includes a top surface having an inclined surface which is inclined at an inclination angle smaller than a right angle in a region extending from a top edge of each rampart to a center peak of an adjacent one of the electroluminescence elements.

8. A method of manufacturing an organic electroluminescence display panel having a plurality of organic electroluminescence elements each having a first display electrode, one or more organic functional layers including a light emitting layer made of an organic compound, and a second display electrode, which are laminated in order on a substrate;
- a plurality of ramparts disposed between said organic electroluminescence elements on said substrate and protruding from said substrate, comprising the steps of;
forming a sealing film for covering said organic electroluminescence elements and at least both side surfaces of said ramparts in such a manner that said sealing film includes a top surface having an inclined surface which is inclined at an inclination angle smaller than a right angle in a region extending from a top edge of each said rampart to a center peak of an adjacent one of said organic electroluminescence elements; and
forming an inorganic passivation film made of an inorganic material on the sealing film for completely covering said sealing film. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18)
