Method of manufacturing organic EL element, organic EL element

摘要

The invention seeks to ensure that a liquid is placed in a predetermined region (without being placed in an adjacent region) with a uniform thickness in the region, when a light emitting layer constituting an organic EL element is placed by, for example, ink jet process. Thin SiO2 film pattern 3 having opening 3a is formed on ITO electrode 2. Next, ultrathin organic film pattern 41 having opening 4b is formed on thin SiO2 film pattern 3. The surface of ultrathin organic film pattern 41 becomes repellent to liquid. Hole transporting layer 61 is formed in opening 4b, and then liquid 7 containing a material for the formation of light emitting layer is discharged thereon by ink jet process. Fluid 7 does not remain on the surface of ultrathin organic film pattern 41 but enters opening 4b.
