a first sealing member that surrounds the outer periphery of the first display part so as to seal the first display part between the first portion of the first flexible substrate and the first portion of the second flexible substrate,

wherein the second display panel includes:

a second portion of the first flexible substrate;

a second portion of the second flexible substrate opposed to the second portion of the first flexible substrate;

a second display part arranged between the second portion of the first flexible substrate and the second portion of the second flexible substrate; and

a second sealing member that surrounds the outer periphery of the second display part so as to seal the second display part between the second portion of the first flexible substrate and the second portion of the second flexible substrate,

wherein the first flexible substrate includes a third portion arranged between the first display part and the second display part,

wherein the second flexible substrate includes a third portion arranged between the first display part and the second display part,

wherein the connection part includes the third portion of the first flexible substrate and the third portion of the second flexible substrate,

wherein a strength of the first protective layer is higher than a strength of the first flexible substrate, and

wherein a strength of the second protective layer is higher than the strength of the first flexible substrate.

2. The display device according to claim 1 , the connection part includes no electrical circuit.

3. The display device according to claim 1 , wherein

the first protective layer is inflexible and the first protective layer keeps the first display part flat, and

the second protective layer is inflexible and the second protective layer keeps the second display part flat.

4. An electronic apparatus comprising:

a first display panel;

a first protective layer included in the first display panel;

a second display panel;

a second protective layer included in the second display panel;

a first flexible substrate included in the first display panel and the second display panel, a portion of the first flexible substrate being included in the connection part, and the first protective layer and the second protective layer being layered on the first flexible substrate; and

a second flexible substrate included in the first display panel and the second display panel, a portion of the second flexible substrate being included in the connection part,

wherein the first display panel includes:

a first portion of the first flexible substrate;

a first portion of the second flexible substrate opposed to the first portion of the first flexible substrate;

a first display part arranged between the first portion of the first flexible substrate and the first portion of the second flexible substrate; and

a first sealing member that surrounds the outer periphery of the first display part so as to seal the first display part between the first portion of the first flexible substrate and the first portion of the second flexible substrate,

wherein the second display panel includes:

a second portion of the first flexible substrate;

a second portion of the second flexible substrate opposed to the second portion of the first flexible substrate;

a second display part arranged between the second portion of the first flexible substrate and the second portion of the second flexible substrate; and

a second sealing member that surrounds the outer periphery of the second display part so as to seal the second display part between the second portion of the first flexible substrate and the second portion of the second flexible substrate,

wherein the first flexible substrate includes a third portion arranged between the first display part and the second display part,
