Abstract:
A liquid crystal dripping method has a problem in that an uncured sealant increases in width at the time of attaching a pair of substrates and thus a liquid crystal material enters the sealant and unevenness occurs in the inner periphery of the sealant. A region in which reduced is the speed of diffusion of liquid crystal at the time of attaching a pair of substrates is provided between a sealant and an orientation film. Further, time for diffusing the liquid crystal and coming in contact with the sealant is made long. Accordingly, the sealant is subjected to photo-curing before the liquid crystal comes in contact with the sealant. The region in which reduced is the speed of diffusion of the liquid crystal is formed using a material for forming a vertical orientation film, a silane coupling agent, a substance having a photocatalytic function, or the like.
