Abstract

PROBLEM TO BE SOLVED: To prevent the deterioration and teardown of a light-emitting element at the time of the pasting of substrates. SOLUTION: An EL substrate 300 comprises a base material 301 having transparency, a plurality of organic EL elements which have individual electrodes 303 and organic EL layers 313, respectively and have in common common electrodes 303 opposed to the individual electrodes 303 interposing the organic EL layers 313, an electrically insulating sealing layer 360 covering the organic EL elements, and connection terminals 340 provided opposed to the individual electrodes 303 interposing the sealing layer 360. On the other hand, the TFT substrate 200 comprises picture element driving circuits 250 for driving organic EL elements, respectively and drawing-out terminals 240 which are provided corresponding to the connectors 340 and connect the picture element driving circuits 250 and the organic EL elements. Then, the EL substrate 300 and the TFT substrate 200 are pasted using an anisotropic conductor 400 so that the connectors 340 and the drawing-out terminals 240 may be one to one and electrically connected.
