摘要:
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 22, an electron transport layer 23, a light emitting layer 24, a hole transport layer 25, a hole injection layer 26 and a second transparent electrode 27 are formed on a glass substrate 21, and a light extraction layer 28 having 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.
