5. A display device according to claim 1, wherein the first state and the second state are changed over by allowing the second display element to move horizontally.

6. A display device according to claim 5, wherein an illumination part is formed on a back surface of the first display element and a light quantity of the illumination part is increased in the second state than in the first state.

7. A display device according to claim 3, wherein a first illumination part is formed on a back surface of the first display element, a second illumination part is formed on a back surface of the second display element, the first illumination part and the second illumination part are turned on in the first state, and the first illumination part is turned on and the second illumination part is turned off in the second state.

8. A display device according to claim 1, wherein an illumination part is formed on a back surface of the first display element and a light quantity of the illumination part is increased in the second state than in the first state.

9. A display device according to claim 1, wherein a first illumination part is formed on a back surface of the first display element, a second illumination part is formed on a back surface of the second display element, the first illumination part and the second illumination part are turned on in the first state, and the first illumination part is turned on and the second illumination part is turned off in the second state.

10. A display device comprising:

a first housing, a second housing and a third housing, wherein

the third housing assumes a first state in which the third housing is overlapped to the second housing and a second state in which the third housing is overlapped to the first housing, and a first display element is arranged in the first housing and a second display element is arranged in the third housing, and

the first display element and the second display element display a two-dimensional image in the first state and the first display element and the second display element display a three-dimensional image in the second state.

11. A display device according to claim 10, wherein the third housing is shifted to the first state and the second state due to the rotation of the third housing.
