  • each substantially prismatic spacer material 150a to 150d is arranged around the first glass substrate 110. It should be noted that the height of these spacer members 150a to 150d (the length in the Z direction in the figure) is larger than the height of the display device 170.
  • Each spacer member 150a to 150d has a hollow inside, and a desiccant such as silica gel may be added thereto.
  • spacer materials 150a to 150d when the glass substrates 110 and 120 are laminated, a sealed space can be formed between them. Further, the display device 170 can be accommodated in the sealed space.
