ORGANIC ELECTROLUMINESCENCE ELEMENT, DISPLAY DEVICE AND LIGHTING DEVICE

摘要

An organic electroluminescence element (100) comprises, on a substrate (1), a pair of electrodes (2, 8) and at least one light emitting layer (5). The light emitting layer (5) contains at least one type of dopant and at least one type of host. The light emitting layer (5) is formed by a coating method using a coating solution dispersed in at least one type of solvent, and the slope of a Guinier plot obtained from X-ray small angle scattering is 1.75 times or less the slope of a Guinier plot obtained from X-ray small angle scattering of a comparative light emitting layer formed by vapor deposition.
