A procedure which comprises a second step of pressing of the Salvia Hispanica L. The thin film transistor unit and a display element unit are laminated on a substrate in this order, and a pixel electrode formed on a substrate side of the display element unit also functions as a drain electrode of the thin film transistor. The reactive agent is controlled to react to provide a gas and optionally components, which a) provides a positive pressure to prevent or counteract buckling and provide structural rigidity to the container and b) and or changes the state or characteristics of the headspace and or contents of the closed container. Trumpet shaped guide portions are formed at the edges of holes of the wire fixing portions of the carrier plate and the circumferential surfaces of a V-shaped tensioner are provided for eliminating slack in the wires.
