摘要:
An organic EL element with a functional layer including at least a hole injection layer, a hole transport layer, and a luminescence layer laminated from a pixel electrode side in order between a pixel electrode as an anode and a counter electrode as a cathode, and a method of manufacturing the organic EL element has a forming process by applying a solution including a low molecular material and a high molecular material to at least one layer among the hole injection layer, the hole transport layer, and luminescence layer, in which the molecular weight of low molecular material is 10,000 or less and the molecular weight of high molecular material is 10,000 to 300,000, and in which a mixing ratio of low molecular material is 10 wt % to 90 wt % with respect to the weight of low molecular material and high molecular material included in the solution.
