Zusammenfassung:	A method for removing gas bubbles (12) in cells (10) filled with liquid crystal material (11) is specified. According to the invention, the filled and hermetically sealed cell (10) is centrifuged, and during this process the cell (10) is arranged with reference to the axis (14) of rotation of the centrifuge in such a way that this axis (14) passes through a cell region which is invisible during later use of the cell (10).
