  • Patent number: 7932984
    Abstract: An end-sealant composition for a liquid crystal display (LCD) panel includes an acrylic polymer resin, a polymeric photoinitiator polymerized into an acrylic chain, and an acryl-philic coupling agent. The end-sealant composition exhibits reduced diffusion into the liquid crystals during an end-sealant forming process. Image defects such as stains around fill ports and incidental images are thereby prevented, so that high quality displays can be prepared. Use of the end-sealant composition can provide high performance for high dielectric constant liquid crystals that are widely used in the fabrication of liquid crystal display panels.
