Abstract
A production method of a hole blocking layer includes: a liquid layer forming step that causes a liquid composition and a surface of a member on which the hole blocking layer is to be formed, to contact with each other thereby forming a liquid layer comprising the liquid composition on the surface of the member on which the hole blocking layer is to be formed, the liquid composition containing a zinc source comprising bis(acetylacetonato)zinc, a complexing agent comprising acetylacetone, and a polar solvent; and a drying step that heats the liquid layer formed by the liquid layer forming step to vaporize the complexing agent and the polar solvent from the liquid layer thereby forming a hole blocking layer comprising zinc oxide on the surface of the member on which the hole blocking layer is to be formed.
