摘要:
At least one of a pair of substrates constituting a liquid crystal device is provided with a composite alignment film including a homeotropic alignment film region and a homogeneous alignment film region, whereby the liquid crystal in contact with the homogeneous alignment film region is surrounded by the region of liquid crystal in a hybrid or homeotropic alignment state and is stably held in a twit alignment state under no electric field which can be continuously transformed into a bend alignment state. As a result, it is possible to provide a liquid crystal device capable of display by utilizing bend alignment with reduced bending voltage and voltage for holding the bend alignment.
