Abstract (en)

In a liquid crystal display comprising an antiferroelectric liquid crystal or a ferroelectric liquid crystal and a light source capable for successively emitting light of different colors, the light source has an arbitrary period during which the light source stops emission when switching from one color to another, and a reset period during which the antiferroelectric liquid crystal or ferroelectric liquid crystal in all pixels is reset to a predetermined state is included within the arbitrary period. The reset period may instead be included in the early part or the last part of a period during which the light source emits light. <IMAGE>
