Ferroelectric liquid crystal cell with particulate adhesive density higher near side
 A liquid crystal cell is constituted a pair of substrates each having an electrode thereon and disposed with their faces having the electrode opposite to each other, a spacer and a particulate adhesive disposed to leave a spacing between the substrates, and a liquid crystal disposed to fill the spacing between the substrates. The particulate adhesive is dispersed at a higher density in a region close to a side of the cell than in a central region of the cell, particularly in a direction of unidirectional alignment axis provided to the substrates. By such uneven distribution of the particulate adhesive, undesirable local thickening of the cell side due to movement of liquid crystal molecules during drive can be suppressed.
