Abstract: An electroluminescent light-emitting device having a light-emitting surface area and including (a) an electroluminescent light-emitting layer containing an electroluminescent material, and (b) an electrode layer formed on one of opposite sides of the electroluminescent light-emitting layer and including a first electrode and a second electrode which are formed in respective predetermined patterns such that the two electrodes are spaced apart from each other by spacing regions provided therebetween, in a direction parallel to a plane of the electrode layer, and such that the two electrodes are electrically insulated from each other by the spacing regions. The electroluminescent light-emitting device has an exposed surface which is located on the other side of the electroluminescent light-emitting layer and to which an electrically conductive ink is applicable.
