The present invention relates to the field of liquid crystal panel manufacturing, and provides a liquid crystal filling device and a liquid crystal panel manufacturing apparatus. The technical solutions of the present invention solve the problem of ionic contamination of liquid crystal due to a quick diffusion rate of liquid crystal dropped on a substrate through an existing liquid crystal filling device. In embodiments of the present invention, the liquid crystal filling device includes a substrate stage and a support used for supporting a liquid crystal container. A first temperature adjustment device is provided on the support, which is used to lower the temperature of the liquid crystal in the liquid crystal container, such that the viscosity coefficient of the liquid crystal in the liquid crystal container is increased. The liquid crystal panel manufacturing apparatus includes the above liquid crystal filling device.
