摘要：The invention provides a method enabling a display material including display elements introduced into divided regions with partition walls to be reclaimed, and a method for manufacturing a display using the method. The color filter substrate is immersed in a developer in the step for reclaiming the base. Alkali can be used as the developer that is capable of being used in the development process for forming the partition walls. The developer is not required to be the actual developer that is used for forming the partition walls. Vibration or stress is applied to the filter element as a display element using an ultrasonic cleaning bath in the step for immersing the base in the developer, and the filter element as a display element is peeled off. The base is washed with water thereafter, followed by drying to return the base to the color filter substrate forming step.
