An example in which the projection is made outside the substrate 810 is shown. In this case, the liquid crystal panel is supported by the tray via only the second substrate 820 in the region 842a and the region 842b.

In each of the above embodiments, a passive matrix type liquid crystal device has been described. However, the electro-optical device of the present invention is not limited to an active type liquid crystal device, but may be a device other than a liquid crystal device, for example, an electroluminescence panel or a plasma display panel. It can also be applied to devices using
