Electric device and production method therefor

1. An electric device comprising:

a support substrate;

an electric circuit provided in a sealing region set on the support substrate;

an electric wiring provided on the support substrate to extend from an inside of the sealing region to an outside of the sealing region for electrically connecting an external electrical signal input/output source with the electric circuit;

a sealing member provided on the support substrate to surround the sealing region; and

a sealing substrate bonded to the support substrate with the sealing member interposed therebetween, wherein

the electric circuit includes an electronic element having an organic layer, and

in a two-dimensional view, a width of an intersection region differs from a width of a non-intersection region excluding the intersection region, the intersection region being a region of the sealing member in which the electric wiring and the sealing member intersect each other.

2. The electric device according to claim 1 , wherein a width A of the sealing member at the intersection region is greater than a width B of the sealing member at the non-intersection region.

3. The electric device according to claim 1 , wherein the electronic element is an organic EL element, an organic photoelectric transducer element, or an organic transistor.

4. A method of producing the electric device according to claim 1 , the method comprising the steps of:

preparing the support substrate on which the electric circuit and the electric wiring are provided;

supplying a sealing material serving as the sealing member along an outer periphery of the sealing region;

bonding the sealing substrate to the support substrate with the sealing material serving as the sealing member interposed therebetween;

irradiating the sealing material serving as the sealing member with an electromagnetic beam to heat and fuse the sealing material; and

forming the sealing member by cooling and hardening the sealing material, wherein

in the step of supplying a sealing material, a width of the supplied sealing material is varied between the intersection region and the non-intersection region.

5. The method of producing the electric device according to claim 4 , wherein throughout an entire region in which the sealing material is arranged is irradiated with the electromagnetic beam at an identical light intensity.

6. The method of producing the electric device according to claim 4 , wherein a spot diameter C of the electromagnetic beam is greater than a width B of the sealing member at the non-intersection region.

7. The method of producing the electric device according to claim 6 , wherein

a width A of the sealing member at the intersection region is greater than the width B of the sealing member at the non-intersection region, and

the spot diameter C of the electromagnetic beam is equal to the width A of the sealing member at the intersection region or greater than the width A.

8. The method of producing the electric device according to claim 6 , wherein

a width A of the sealing member at the intersection region is greater than the width B of the sealing member at the non-intersection region, and

the spot diameter C of the electromagnetic beam is smaller than the width A of the sealing member at the intersection region.
