PCT No. PCT/JP96/01834 Sec. 371 Date Feb. 26, 1997 Sec. 102(e) Date Feb. 26, 1997 PCT Filed Jul. 2, 1996 PCT Pub. No. WO97/02510 PCT Pub. Date Jan. 23, 1997A liquid crystal device used for electro-optical devices, in which each parameter of the liquid crystal having layer structures is specified to provide a liquid crystal high in stress resistance and capable of gray scale display. The liquid crystal held between a pair of parallel substrates is either ferroelectric or antiferroelectric and represents layer structures. A plurality of substrate interface tilt angles can be set for the layer structures. The layer structures can be configured asymmetric or symmetric about a plane intermediate between the parallel substrates. With this configuration, a liquid crystal device is constructed having a plurality of layer structures including at least one layer structure, which has (1) a substrate interface layer tilt angle of 0 DEG to 3 DEG and the c director pretilt of 3 DEG to 5 DEG , or (2) a substrate interface layer tilt angle of 4 DEG to 7 DEG and the c director pretilt of 0 DEG to 3 DEG , or (3) a substrate interface layer tilt angle of 8 DEG to 20 DEG and the c director pretilt of 9 DEG to 90 DEG or less.
