1. A manufacturing method of an electroluminescent display device, comprising:
forming an organic electroluminescent display unit on a device substrate;
attaching the device substrate having the organic electroluminescent display unit thereon to a sealing substrate using a sealing
resin so that the organic electroluminescent display unit is sealed in a space formed by the device substrate, the sealing
substrate and the sealing resin; and
forming a graphic symbol outside the space in which the organic electroluminescent display unit is sealed by applying a laser
to a layer disposed on the device substrate after the attaching of the device substrate and the sealing substrate.
