Method of manufacturing flat-panel display device, apparatus for manufacturing flat-panel display device, and flat-panel display device

An apparatus for manufacturing a flat-panel display device, comprising:

• a hermetic vacuum chamber having an openable/closable door;
• a stage provided in the vacuum chamber;
• a heater provided in the vacuum chamber and configured to heat the stage;
• an elastic sheet provided in the vacuum chamber, and configured to be movable so as to partition the vacuum chamber into a pressure chamber that forms an enclosed space and an accommodation chamber that accommodates the heater and the stage;
• a sheet movement mechanism configured to effect movement of the elastic sheet from outside the vacuum chamber;
• an evacuation unit configured to evacuate the vacuum chamber;
• and
• a first supply unit configured to supply an inert gas to the pressure chamber.

A flat-panel display device manufactured by a manufacturing method comprising:

• laminating a thermosetting resin film on a sealing substrate;
• stacking the sealing substrate having the thermosetting resin film laminated thereon, and an element substrate having a light-emitting element together under a vacuum atmosphere with the thermosetting resin film and the light-emitting element facing inwardly, and with a frame-shaped sealing material around the thermosetting resin film interposed the two substrates;
• joining the sealing substrate and the element substrate together under a vacuum atmosphere by the sealing material situated between the sealing substrate and the element substrate stacked together;
• and
• heat-curing the thermosetting resin film situated between the sealing substrate and the element substrate laminated together, under an air atmosphere.
