This invention provides a process for producing a color conversion filter using an ink jet recording method, which can form a color conversion layer at a desired position without the need to separately form partition walls, and a process for producing an organic EL display. The process for producing a color conversion filter is characterized by comprising (a) the step of forming a black matrix having a plurality of opening parts on a transparent substrate, (b) the step of forming at least two types of color filter layers independently of each other, at least two of the color filter layers being superimposed on top of each other, on a black matrix to which dissimilar color filter layers are adjacent, to form a partition wall, and (c) the step of forming a color conversion layer by ink jet recording onto at least one of the color filter layers.
