Abstract: A work in progress includes: a pair of glass substrates arranged to face each other; a peripheral wall having a frame shape and disposed between the pair of glass substrates; a boundary wall; and an evacuation port. The boundary wall hermetically separates an internal space, surrounded with the pair of glass substrates and the peripheral wall, into an evacuation space, a buffer space, and a ventilation space.
