The invention discloses a crystal pouring device and method for a flexible liquid crystal cell. The device comprises a clamp, wherein the clamp is used for clamping the flexible liquid crystal cell into which crystal is to be poured and generating even surface pressure on the flexible liquid crystal cell. Before a crystal pouring machine is vacuumized, even surface pressure is generated on the surface of the flexible liquid crystal cell by means of the clamp, and liquid crystal is heated to reduce the viscosity of the liquid crystal. After the crystal pouring machine is vacuumized, the crystal pouring machine is in a pressure maintaining state to enable the interior vacuum degree of the flexible liquid crystal cell to be balanced, and then crystal pouring and inflation are conducted, so that pressure difference is prevented from being generated between the inside and outside of the flexible liquid crystal cell during vacuumization and cracking of the liquid crystal cell caused by expansion is avoided. The crystal pouring device and method for the flexible liquid crystal cell solve the problem that cracking of the liquid crystal cell can be caused by expansion due to the fact that pressure difference is generated between the inner surface and outer surface of the flexible liquid crystal cell during vacuumization for crystal pouring, productivity is increased, and production cost is reduced.
