PROBLEM TO BE SOLVED: To provide a liquid crystal(LC) pressurizing and feeding device with which the lack of injection of LC liquid, permeation of air from an injecting port or the like after injection or occurrence of dispersion in the thickness of an LC panel is reduced by highly accurately controlling the injection pressure of an LC liquid by using a pressurizing mechanism. SOLUTION: This device is provided with a means 124 for deforming an LC container, means 126 for driving and controller 125 and with a means for directly detecting the pressure near an injection port 10 or means 127 for measuring a driven quantity and a control part 128 for determining a controlled variable from the relation of deformation quantity and pressure, thereby the liquid pressure of the LC liquid near the injection port is arbitrarily regulated. Thus, the lack of injection, permeation of air from the injection port after the injection or occurrence of dispersion or the like in the thickness of the LC panel is suppressed.
