Abstract
An object of the present invention is to provide an organic light emitting element where light emitted from the light emitting layer is efficiently emitted to the outside, and thus, the efficiency of light emission is higher. The present invention provides an organic light emitting element where a first reflective electrode, an electron transport layer, a light emitting layer, a hole transport layer, a hole injection layerand a second transparent electrodeare formed on a glass substrate, and a light extraction layerhaving an average index of refraction of 1.4 made of titanium particles having an index of refraction of 2.6 and an average particle diameter of 150 nm and silica sol.
