After bonding a first substrate layer in which a plurality of element substrates is formed on a support plate and a second substrate layer in which a plurality of counter substrates is formed on a support plate, these substrate layers are divided into a plurality of display panels. Ridge-like ribs of a covalently or ionically bonding inorganic material are formed along edges of the element substrate and the counter substrate. The dividing includes scribing the support plates along the ribs, and flexing and breaking the support plates.
