Abstract:
1. An organic electroluminescence element, comprising, a substrate; a pixel electrode formed on said substrate; a partition wall sectioning said pixel electrode; one or more insulating layers for covering said partition wall; an organic light emitting medium layer arranged on said pixel electrode; wherein said organic light emitting medium layer includes a hole transport layer and an organic light emitting layer, said organic light emitting layer formed on said hole transport layer; said hole transport layer comprising an oxide of molybdenum; and a cathode arranged on said organic light emitting medium layer so as to face said pixel electrode wherein said insulating layers for covering said partition wall includes a first insulating layer for covering said partition wall corresponding to said hole transport layer, and wherein said insulating layers for covering said partition wall includes a second insulating layer for covering said partition wall corresponding to said organic light emitting layer, and wherein a cross section of said partition wall has a shape of a plurality of steps.
