Abstract

An electronic device capable of transmitting and receiving a mail through an internet usually has from 12 to 20 operation keys inclusive of numerical keys and special keys. In order to input Japanese characters inclusive of “kanji” and special characters as data, complex operations must be executed by changing over the input mode. A portable data terminal as represented by a cellular phone or an electronic device such as a data terminal as represented by a personal computer or a desk top telephone, has such a shape that the first center-line of the first housing and the second center line of the second housing come into agreement and in parallel with each other only in a state where the first housing and the second housing are folded by the hinge.

Claims

1. An electronic device comprising:

a housing comprising a display unit;

wherein a first direction of a symbol or a picture is displayed on the display unit when arranging the housing in a vertical direction,

wherein a second direction of a symbol or a picture is displayed on the display unit when arranging the housing in a lateral direction, and

wherein the first direction is different from the second direction.

2. An electronic device according to claim 1,

wherein the display unit comprises a plurality of pixels, and

wherein each of the plurality of pixels comprises a photoelectric conversion element.

3. An electronic device according to claim 1,

wherein the display unit comprises a plurality of pixels, and

wherein each of the plurality of pixels comprises first to fifth transistors, a capacitor, and a light-emitting element.

4. An electronic device according to claim 1, wherein the electronic device is an information terminal

5. An electronic device according to claim 1, wherein the electronic device is a cellular phone.

6. An electronic device according to claim 1, wherein the electronic device is a personal digital assistant.

7. An electronic device comprising:

a first housing including a first display unit;

a second housing including a second display unit; and

wherein each of first directions of symbols or pictures displayed on the first display unit and the second display unit is the same when arranging the first housing and the second housing in a vertical direction,

wherein each of second directions of symbols or pictures displayed on the first display unit and the second display unit is the same when arranging the first housing and the second housing in a lateral direction, and

wherein each of the first directions is different from each of the second directions.

8. An electronic device according to claim 7,

wherein at least the first display unit comprises a plurality of pixels, and

wherein each of the plurality of pixels comprises a photoelectric conversion element.

9. An electronic device according to claim 7,

wherein at least the first display unit comprises a plurality of pixels, and

wherein each of the plurality of pixels comprises first to fifth transistors, a capacitor, and a light-emitting element.

10. An electronic device according to claim 7,

wherein a first center line of the first housing and a second center line of the second housing are in parallel with each other only in a state where the first housing and the second housing are folded via the hinge,

wherein the first center line and the second center line are inclined relative to each other in a state where the first housing and the second housing are opened via the hinge,

wherein the second housing includes a transmitting unit while the first housing includes a receiving unit, and

wherein the receiving unit is provided at a first end of the first housing opposite a second end of the first housing at which the hinge is located.

11. An electronic device according to claim 7,

wherein at least one of the first display unit and the second display unit includes one selected from the group consisting of a liquid crystal display device and a light emitting device.

12. An electronic device according to claim 7, wherein the electronic device is an information terminal

13. An electronic device according to claim 7, wherein the electronic device is a cellular phone.

14. An electronic device according to claim 7, wherein the electronic device is a personal digital assistant.

15. An electronic device comprising:

a first substrate;

a thin film transistor over the first substrate;

an insulating film having a contact hole over the thin film transistor;

a first electrode over the insulating film, the first electrode being electrically connected to the thin film transistor through the contact hole;

a bank covering an edge portion of the pixel electrode;

a second substrate over the bank; and

a first seal member for bonding the first substrate and the second substrate,

wherein the bank is not in contact with the seal member, and

wherein a part of the bank is filled in the contact hole.

16. An electronic device according to claim 15, further comprising;

a second seal member formed outside of the first seal member and covering a side surface of the first seal member.

17. An electronic device according to claim 15, wherein the electronic device is an information terminal

18. An electronic device according to claim 15, wherein the electronic device is a cellular phone.

19. An electronic device according to claim 15, wherein the electronic device is a personal digital assistant.
