Abstract
In a light emitting panel, organic EL panels are laminated in a step-like shape in a front-back direction to form organic EL panel groups, and the organic EL panel groups are further laminated in a step-like shape in a left-right direction. Each of the organic EL panels comprises a power feed part at one side of the transparent support substrate in the left-right direction. The power feed part of each of the organic EL panels is aligned with other power feed parts in the front-back direction at one side of the left-right direction, and is disposed at a position that allows the power feed part to overlap with a laminate of an organic EL panel of an adjacent organic EL panel group.
Claims9
A light emitting panel, comprising:
- a plurality of organic EL panels each of which comprises a laminate formed by laminating a positive electrode, an organic compound layer and a negative electrode on a transparent support substrate and a transparent sealing member to seal the laminate, in which the plurality of organic EL panels are laminated in a step-like shape in a front-back direction to form a plurality of organic EL panel groups, and the plurality of organic EL panel groups are further laminated in a step-like shape in a left-right direction,
- wherein each of the plurality of organic EL panels comprises a power feed part which is formed by exposing a part of the positive electrode and a part of the negative electrode of the laminate from the transparent sealing member at one side of the transparent support substrate in the left-right direction, and
- the power feed part of each of the plurality of organic EL panels is aligned with other power feed part in the front-back direction at one side of the left-right direction, and is disposed at a position that allows the power feed part to overlap with a laminate of an organic EL panel of an adjacent organic EL panel group.
A method for manufacturing a light emitting panel in which a plurality of organic EL panels are laminated in a step-like shape in a front-back direction to form a plurality of organic EL panel groups, and the plurality of organic EL panel groups are further laminated in a steplike shape in a left-right direction, comprising the steps of:
- manufacturing each of the plurality of organic EL panels by laminating a positive electrode, an organic compound layer and a negative electrode on a transparent support substrate to form a laminate, and sealing the laminate by a transparent sealing member such that a part of the positive electrode and a part of the negative electrode are exposed, and
- arranging the plurality of organic EL panels in a matrix of the front-back direction and the left-right direction such that a power feed part of each of the plurality of organic EL panels is aligned with other power feed part at one side of the left-right direction, the power feed part being the exposed part of the positive electrode and the exposed part of the negative electrode of each of the plurality of organic EL panels.
