A liquid crystal cell and method for fabricating the same, a liquid crystal display panel, and a display device are disclosed. The liquid crystal cell comprises an active area and a dummy area, and comprises a first and second substrate which are arranged oppositely and separated by spacers, and liquid crystal arranged between the first and second substrate. 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, so as to compensate variation in the volume of liquid crystal when temperature varies. Not only defects of gravity mura at high temperature and bubbles at low temperature are eliminated to spread LC Margin, but also the scope of application environment for the liquid crystal display panel is expanded.
