PURPOSE: To prevent generation of orientation defects and to provide the titled element which can sufficiently exhibit high responsiveness and memory effect characteristic by specifying the value of the ratio between the film thickness of color filters of respective picture elements and spacings between the respective picture elements adjacent to each other.
CONSTITUTION: This ferroelectric liquid crystal element 1 is formed with the color filters of the respective picture elements to nearly the same film thickness. The film thickness of the color filters of the respective picture elements, designated as d(μm), and the spacings between the respective picture elements adjacent to each other, designated as d(μm), are specified to 0≤l/d≤5. The flatness of a substrate is, therefore, improved and such a step which generates the orientation defects on the surface in contact with a liquid crystal phase 4 is eliminated. The liquid crystal phase 4 sandwiched by the substrate having the good flatness is gradually expanded in the liquid crystal phase region by slow cooling and forms the liquid crystal phase 4 of a uniform monodomain in the process of the temp. drop shifting from the isotropic phase to the mesomorphic phase. The characteristics of the ferroelectric liquid crystal 4 are thereby satisfactorily exhibited.
