Abstract:
Provided is a liquid crystal sealing agent with which a cured article having a low Young's modulus is obtained, and which is configured such that, when the sealing agent is used in a liquid crystal display panel that has been cured, and the liquid crystal panel is subjected to a pressure treatment, the generation of roughness is suppressed. The liquid crystal sealing agent: provides a cured article having a Young's modulus of at least 0.5 GPa but less than 3.0 GPa at 23°C; and includes a thermosetting agent (E) and a thermosetting compound (A) having an epoxy group in a molecule.
