The present invention provides a manufacturing method of a light emitting device
in which the number of display panels manufactured from one substrate is increased
and display panel is mass produced is provided. One feature of the invention is
that the shipping is performed not by separating the substrate over which a plurality
of light emitting regions is formed and attaching the FPC to the each piece thereof
but before separating, namely in the incomplete state (that can be also referred
to as semi end products). However, the invention has a structure in which the inspection
can be partly carried out before the shipping.
