Abstract
A plurality of panels (40) are cut from a large substrate (mother substrate) including a lower large substrate (41A) and an upper large substrate (42A). For each panel (40), a frame-shaped seal (47) and a connection electrode forming section (C) are formed in the large substrate. Since the left side (47c) of the frame of a panel (40) is close to the right side (47b) of the frame of the left-adjacent panel, these sides of the seals are formed from a sealing material containing a lower density of spacers. Since the upper side (47a) of the frame of a panel (40) is separated from the lower side (47d) of the frame of the upper adjacent panel (40) by an extension (C′) for the connection electrodes, these seal members are formed from a sealing material containing a higher density of spacers.
