Title:
ORGANIC ELECTROLUMINESCENCE ELEMENT AND LUMINAIRE
Document Type and Number:
Japanese Patent JP2017097948
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an organic electroluminescence element in which the contour of a light source is difficult to be viewed from the outside while suppressing reduction of a light extraction efficiency.SOLUTION: An organic EL element 1 has a planar shape, and includes a first electrode 2 having light transmittance, a second electrode 3 paired with the first electrode 1, an organic light emitting layer 4 disposed between the first electrode 2 and the second electrode 3, and a diffusion structure. The diffusion structure more greatly diffuses light which passes from the organic light emitting layer 4 through the vicinity of the outer peripheral edge of the first electrode 2 and is emitted to the outside, as compared with light which passes from the organic light emitting layer 4 through the central portion of the first electrode 2 and is emitted to the outside.SELECTED DRAWING: Figure 1
