(57) [Abstract] [Problem] To enable bonding of upper and lower substrates at room temperature, and to realize adhesive strength and moisture resistance reliability, flexibility, and durability that can withstand multi-faced machining. A predetermined gap is formed by curing for a short time, and contaminants do not flow out of the liquid crystal from the cured sealing agent, and degassing for removing bubbles after kneading with the added glass fiber, for example, is unnecessary. A sealing agent for sandwiching liquid crystal by arranging a pair of transparent substrates to face each other at a predetermined interval is made of (a) a liquid epoxy resin, and (b) a novolak resin having a softening point of 75 ° C. or less by a ring and ball method. Curing agent, (c) a filler having a particle size of 10 μm or less, and (d) a curing accelerator as essential components, It is assumed that the mixture of the component (a) and the component (b) is liquid or has a softening point of 50 ° C. or less as measured by a ring and ball method. |
