To provide a method for manufacturing a liquid crystal device capable of certainly eliminating a trace of injection generated in the case of liquid crystal injection.

In the method for manufacturing the liquid crystal device comprising a liquid crystal held between a pair of substrates placed opposite to each other, the liquid crystal is injected into a gap surrounded by the pair of substrates and a sealing material held in between, end-sealing the injection port and the liquid crystal is subsequently subjected to isotropic treatment within 24 hours.
