させることができる。According to the present invention, a laminate in which an organic layer having at least a light-emitting layer is sandwiched between a first electrode and a second electrode, a light-transmitting substrate on which the laminate is provided, and the light-transmitting substrate A sealing member provided on the top with an adhesive and covering the stacked body, and provided inside at least one contact surface of each contact surface where the sealing member and the translucent substrate are in contact with each other. A receiving portion capable of receiving the adhesive, since the adhesive does not adhere to the laminate even when the application amount of the adhesive varies.
There is no possibility of damaging or damaging the laminate, and the yield in the manufacturing process of the organic EL panel can be improved.
