<P>PROBLEM TO BE SOLVED: To provide an organic EL element for which color unevenness within a light-emitting surface is suppressed. <P>SOLUTION: An organic EL element has an organic layer 3 containing two or more dopant-containing layers 1 and one or more dopant non-containing layers 2. A light emitting surface A is divided into plural sections each having a predetermined size as plural elements S. The average film thickness of each element S in at least one of the two or more dopant-containing layers 1 is in the range from 90% to 110% of the average film thickness of the whole dopant-containing layer 1. The average chromaticity of each element represented by u' value and v' value of an CIE1976(u',v') chromaticity diagram is in the range from 98% to 102% of the average chromaticity of the whole light emitting surface A for both the u' value and the v' value. <P>COPYRIGHT: (C)2013,JPO&INPIT |
