  An object of the present invention is to provide a method capable of producing, with high productivity, a liquid composition that does not cause uneven coating or nozzle clogging and that does not contain eluted substances that cause a decrease in luminance lifetime. The present invention relates to a method for producing a liquid composition comprising a phosphorescent material and an organic solvent, the method comprising the steps of: dissolving a phosphorescent material in an organic solvent to prepare a mixed liquid, and filtering the mixed liquid obtained in the above step by a filtering device; wherein the filtering device comprises a housing or holder, a fluororesin membrane filter, and a filter support member; a material of a portion of the housing and holder, the portion being in contact with the mixed liquid, is a metal alone or a mixture of a metal and at least one member selected from the group consisting of glass, fluororesins, polyethylene not containing a phosphorus antioxidant, and polyethylene not containing an oxidized phosphorus antioxidant; and a material of a portion of the filter support member, the portion being in contact with the mixed liquid, is at least one member selected from the group consisting of metals, glass, fluororesins, polyethylene not containing a phosphorus antioxidant, and polyethylene not containing an oxidized phosphorus antioxidant.

  本发明的目的是提供一种能够以高生产率生产液体组合物的方法，这种液体组合物不会造成涂层不均匀或喷嘴堵塞，并且不含有会导致发光寿命缩短的洗脱物质。本发明涉及一种生产包含磷光材料和有机溶剂的液体组合物的方法，该方法包括以下步骤：将磷光材料溶解在有机溶剂中以制备混合液体，以及通过过滤装置过滤上述步骤中获得的混合液体；其中，过滤装置包括外壳或支架、荧光膜过滤器和过滤器支撑部件；与混合液体接触的外壳和支架的一部分的材料是单独的金属或金属与至少一种选自玻璃、氟树脂、不含磷抗氧化剂的聚乙烯和不含氧化磷抗氧化剂的聚乙烯组成的组的成员的混合物，以及外壳和支架的一部分的材料是单独的金属或金属与至少一种选自玻璃、氟树脂、不含磷抗氧化剂的聚乙烯和不含氧化磷抗氧化剂的聚乙烯组成的组的成员的混合物；与混合液体接触的过滤支撑件的一部分的材料是选自金属、玻璃、氟树脂、不含磷抗氧化剂的聚乙烯和不含氧化磷抗氧化剂的聚乙烯组成的组中的至少一种。
