Abstract:
A liquid crystal device, comprising:a pair of substrates and a liquid crystal disposed in an alignment state between the substrates so as to form a plurality of pixels which in combination form an optical modulation region together with spacings between adjacent pixels,at least one of the substrate having a surface contacting the liquid crystal and including a first region having a larger uniaxial alignment control force and a second region having a smaller or substantially no uniaxial alignment control force and providing the plurality of pixels, said first and second regions being both disposed in the optical modulation region and respectively acting on the liquid crystal in the optical modulation region,whereby phase transition from isotropic phase to mesomorphic phase on temperature decrease has been initiated from a portion of the liquid crystal contacting the first region and enlarged toward the second region to place the liquid crystal in the alignment state.
