摘要：
The present disclosure provides an organic light-emitting element (300) including a first electrode (2), an organic compound layer, and a second electrode (7), wherein the organic compound layer includes a charge transport layer (4), and the charge transport layer includes a first charge transport layer (401), a second charge transport layer (402), and a third charge transport layer (403) in this order, and the first charge transport layer, the second charge transport layer, and the third charge transport layer satisfy Formulas (1) and (2) below: μ 1 > μ 2 > μ 3 d 1 + d 2 d 3 in Formula (1), µ1, µ2, and µ3 are charge mobilities of the first to third charge transport layers, and
in Formula (2), d1, d2, and d3 are layer thicknesses of the first to third charge transport layers.
in Formula (2), d1, d2, and d3 are layer thicknesses of the first to third charge transport layers.
