Display device and manufacturing method thereof

A display device, comprising:

• a pair of spaced apart and substantially gas impermeable support barriers integrally connected at a respective integrally formed end to one of an upper panel and a lower panel of the display device and each having its non-integrally formed other end in contact with the respective other one of the upper panel and the lower panel;
• and
• a substantially evacuated vacuum region positioned between the spaced apart support barriers, the vacuum region being in a force exerting further coupling with at least one of the upper panel and the lower panel so as to force together the upper and lower panels due at least in part to a pressure difference between the vacuum region and an exterior atmosphere, wherein the display device comprises a display area and a peripheral area around the display area, the pair of support barriers comprising an inner support barrier and an outer support barrier, the inner support barrier completely and sealingly surrounding the display area, and the outer support barrier completely and sealingly surrounding the display area.
