1. A liquid crystal cell, comprising an active area and a dummy area, and comprising a first and second substrate which are arranged oppositely and separated by spacers, and liquid crystal arranged between the first and second substrate,wherein the liquid crystal cell further comprises a volume variation compensating component which is arranged in the active area, and the volume variation compensating component comprises a material with a thermal expansion coefficient opposite to that of the liquid crystal, wherein when the liquid crystal decreases in volume due to temperature variation, the volume variation compensating component increases in volume, or when the liquid crystal increases in volume due to temperature variation, the volume variation compensating component decreases in volume,wherein the spacers are post spacers, andwherein the spacers comprise main spacers and sub-spacers with a height smaller than that of the main spacers, and the volume variation compensating component forms the sub-spacers.
