A display device including a resin layer, a TFT layer being an upper layer with respect to the resin layer, and a light-emitting element layer being an upper layer with respect to the TFT layer, in which a bending section is provided on a peripheral edge, includes a terminal wiring line that passes through the bending section and is connected to a terminal, and an auxiliary wiring line, and the terminal wiring line includes a first wiring line and a second wiring line that are positioned on both sides of the bending section, and a third wiring line that passes through the bending section and is electrically connected with each of the first wiring line and the second wiring line, and the auxiliary wiring line is superimposed on the third wiring line via a flexible insulating film in the bending section.

Provided is a method of manufacturing a light emitting device, comprising: preparing a base body having a concave portion; disposing a light emitting element at the bottom of the concave portion; disposing a first resin containing first phosphor particles having an average particle size of 10 m or more and 30 m or less and a first filler having an average particle size of 5 m or more and 20 m or less to cover the light emitting element; centrifugally precipitating the first phosphor particles and the first filler toward the base body; temporarily curing the first resin; disposing a second resin containing second phosphor particles and a second filler having an average particle size of 5 nm or more and 100 nm or less on the first resin temporarily cured; centrifugally precipitating the second phosphor particles and the second filler toward the first resin; and curing the first and second resins.

In the display device, the plurality of display bodies are jointed together and fixed to the elongated flexible circuit board.

A method of manufacturing a display device includes a step of forming a first inorganic film constituting a sealing film and a step of forming an organic film constituting the sealing film. Between these steps, the method further includes a foreign matter inspection step of inspecting a substrate surface on which the first inorganic film has been formed and identifying the location of a foreign matter adhering to the substrate surface, and a partial ejection step of using an ink-jet method to eject ink to be formed a part of the organic film at the location of the foreign matter on the substrate surface identified in the foreign matter inspection step.

An electroluminescent display is flexible and stretchable, and therefore able to be attached to a textile. All interior layers of the electroluminescent display can be made using a screen printing process which can be scaled for volume production.

Dn.sup.1 represents NR.sup.11, an O atom, or an S atom. Ac.sup.1 represents an electron absorbing substituent, an aryl group having an electron absorbing substituent, or an electron deficient heteroaryl group. The ring Z.sup.1 represents an arylene group or a heteroarylene group. L.sup.1, L.sup.2 and L.sup.3 represent specific linking groups. u1 represents 0 or 1, and in the case where u1 is 1, the ring thus formed is not an aromatic ring. n1 and q1 represent 0 or 1, and in the case where any one of n1 and q1 is 0 and n1 or q1 is 1, the rings thus formed are not all aromatic rings. When Ac.sup.1 is a pyridine ring, at least one of n1 and q1 is 1.)
