Method for eliminating materials, method for reclaiming base, method for manufacturing display, and electronic appliances comprising display manufactured by the manufacturing method
View Patent ↗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.
1. A method for eliminating a material disposed on a region divided by partition walls formed on a base, comprising:
eliminating the material while the partition walls remain on the base.
2. The method for eliminating the material according to claim 1 ,
further including forming the partition walls by exposing a radiation sensitive material to radiation and by developing the exposed material, and
peeling the material off or dissolving the material by a development substance that is capable of being used for development.
3. The method for eliminating the material according to claim 2 , further including applying vibration or stress to peel off or dissolve the material.
4. The method for eliminating the material according to claim 1 , further including forming the material by introducing a liquid material into a region divided by the partition walls.
5. The method for eliminating the material according to claim 4 , further including eliminating the material as a material before solidification.
6. The method for eliminating the material according to claim 1 , the material being a filter element constituting a color filter.
7. The method for eliminating the material according to claim 1 , the material being an EL substance.
8. A method for reclaiming a base, comprising:
the method for eliminating a material disposed on a region divided by partition walls formed on the base; and
subsequently forming a material on the base.
9. A method for manufacturing a display, comprising:
forming partition walls on a base;
introducing a display element in a region divided by the partition walls to form the base;
inspecting the base;
detecting a defective display element, while eliminating the display element, and while the partition wall remains on the base; and
eliminating the defective display element; and
subsequently disposing another display element again in the region divided by the partition wall.
10. The method for manufacturing the display according to claim 9 ,
the forming partition walls including forming the partition wall by irradiating a radiation to a radiation sensitive material and by developing the irradiated material; and
the eliminating including peeling the display element off or dissolving the display element by a development substance that is capable of being used for development.
11. The method for manufacturing the display according to claim 10 , further including applying vibration or stress to the display element for peeling off or dissolving the display element.
12. The method for manufacturing the display according to claim 9 , the introducing a display element including introducing a liquid material as the display element in the region divided by the partition wall.
13. The method for manufacturing the display according to claim 12 , further comprising;
solidifying the display element when no defective display element has been detected; and
the eliminating the display element including eliminating the display element before solidification.
14. The method for manufacturing the display according to claim 9 , the display element being a filter element constituting a color filter.
15. The method for manufacturing the display according to claim 9 , the display element being an EL substance.
16. An electronic appliance, comprising:
a display manufactured by the manufacturing method according to claim 9 .
