  • Publication number: 20180017817
    Abstract: The present invention provides a sealant composition, a display panel and a method for manufacturing the same and a display device. For the sealant composition, the display panel and the display device provided in the present invention, the issues such as contamination of liquid crystal, peripheral defects and line residual image due to the incomplete curing of the sealant are prevented because the sealant composition comprises light converting material which could convert the incident light into the light for curing the sealant, and thus the sealant which cannot be irradiated directly by the incident light also could be cured by the converted light obtained from the light converting material.
