ORGANIC ELECTROLUMINESCENCE ELEMENT, METHOD FOR PRODUCING ORGANIC ELECTROLUMINESCENCE ELEMENT AND ORGANIC ELECTROLUMINESCENCE MODULE

摘要

Provided is an organic electroluminescence element that eliminates uneven light emission and changes a light emitting pattern. The organic electroluminescence element including: a supporting substrate; a first electrode; N sets of light emitting units including one or more organic functional layers, where N represents an integer of 2 or more; and one or more (N−1) sets of intermediate metal layers with optical transparency, each disposed between the adjacent light emitting units; and a second electrode. Herein, at least one organic functional layer of each light emitting unit is a layer subjected to patterning using a mask during formation of the organic functional layer, a layer subjected to patterning via light irradiation after formation of the organic functional layer, or a layer subjected to patterning using a mask during formation of the organic functional layer and further subjected to patterning via light irradiation after the formation of the organic functional layer.

1. An organic electroluminescence element comprising:
a supporting substrate; a first electrode disposed on the supporting substrate; N sets of light emitting units each including one or more organic functional layers, where N represents an integer of 2 or more; (N−1) sets of intermediate metal layers with optical transparency and each disposed between the adjacent light emitting units; and a second electrode, as being stacked to form the organic electroluminescence element, wherein at least one organic functional layer of the light emitting unit is a layer subjected to patterning using a mask during formation of the organic functional layer, a layer subjected to patterning via light irradiation after formation of the organic functional layer, or a layer subjected to patterning using a mask during formation of the organic functional layer and further subjected to patterning via light irradiation after the formation of the organic functional layer, with respect to the N sets of light emitting unit, and the N sets of light emitting units are electrically operable individually or simultaneously.
