A liquid drop arranging device is provided for arranging liquid drops made of liquid crystal on a substrate. The liquid drops are arranged so that adjacent liquid drops reach the substrate with a first pitch equal to or less than the diameter of the liquid drops immediately before reaching the substrate. When the diameter of the liquid drops at the moment the liquid drops reach the substrate is the first diameter and the diameter of the liquid drops at the moment the liquid drops spread from the first diameter is a second diameter that is larger than the first diameter, the liquid drops are arranged so that the entire outline of a liquid drop of the first diameter contacts a liquid drop of the first diameter adjacent to the liquid drop when the liquid drops reach the substrate.
