Patent ID: 6995507

Claim:
An organic electroluminescence element comprising organic layers formed by depositing two or more organic materials by vacuum evaporation, comprising, depositing each material under such control that an ni value of each organic material is k±0.5 wherein k is a constant from 2 to 5, when a relationship between a deposition position and a film thickness of a material i on the substrate is approximated by the following equation (1): D i /D 0i α( L 0 /L i ) 3 cos ni θ i (1) wherein L 0 is a distance from an evaporation source to a plane of the substrate in a perpendicular direction, D 0i is a film thickness of the material i at an intersection point of a perpendicular line from the evaporation source to the plane of the substrate, and D i is a film thickness of the material i at a position on the substrate that is apart from the evaporation source by a distance L i in a direction of an angle θ i against the perpendicular line.
