Abstract
There is disclosed a ferroelectric liquid crystal color-display panel capable of preventing defects in liquid crystal orientation, resulting from the glass substrate bending, particularly in the end portion of effective display area, by the use of a gap-retaining material, such as silica or alumina beads, in the sealant of the panel, wherein the diameter T of the gap retaining material satisfies a relation: ##EQU1## in which t.sub.1 is the cell gap in the display area and t.sub.2 is the thickness of color filter provided in the display area.
