Disclosed is a method for manufacturing an organic thin film pattern, an organic thin film pattern, an array substrate, and a display device. The method for manufacturing the organic thin film pattern includes the steps of forming a liquid droplet in a recessed portion of a thin film definition layer on a substrate, the liquid droplet being a solution containing an organic functional material, gelatinizing the liquid droplet, and performing a drying process on gelatinized liquid droplet to form an organic thin film pattern.
