Light-emitting devices are formed on a support substrate, whereas a black
matrix is provided on a transparent opposed substrate. The support
substrate and the opposed substrate are adhered to each other in the
condition where the display devices are sealed with an adhesive resin and
the adhesive resin is charged between the support substrate and the
opposed substrate. In this case, alignment of the support substrate and
the opposed substrate is conducted so that the surface of the opposed
substrate provided with the black matrix is faced to the surface of the
support substrate provided with the light-emitting devices and the black
matrix is disposed faced to the spaces between the light-emitting devices.
The alignment is conducted by disposing alignment marks provided on the
surface of the support substrate provided with the light-emitting devices
and alignment marks provided on the opposed substrate into a predetermined
condition.
