Abstract

Provided is an electro-optical panel including a first area in which a circuit is formed and a first terminal area and a second terminal area that are arranged side-by-side in a Y direction when viewed from the first area. The first terminal area and the second terminal area are each provided with a terminal group including a plurality of terminals arranged in an X direction different from the Y direction, and at least one of wires from the first terminal area to the first area and from the second terminal area to the first area extends from between the first terminal area and the second terminal area and reaches the first area through an area outside of the first terminal area when viewed from a central axis of the electro-optical panel extending in the Y direction.

Claims (37)

1. An electro-optical panel, comprising:

a circuit area in which a circuit is formed; and

a first terminal area and a second terminal area that are arranged side-by-side in a first direction viewed from the circuit area, wherein

the first terminal area and the second terminal area are each provided with a terminal group including a plurality of terminals which are arranged in a second direction different from the first direction, and

at least one of wires from the first terminal area to the circuit area and from the second terminal area to the circuit area extends from between the first terminal area and the second terminal area and reaches the circuit area through an area outside of the first terminal area viewed from a central axis of the electro-optical panel extending in the first direction.

2. The electro-optical panel according to claim 1 , wherein

the terminal group arranged in the first terminal area and the terminal group arranged in the second terminal area have a common signal arrangement.

3. The electro-optical panel according to claim 1 , wherein

the terminal group arranged in the first terminal area and the terminal group arranged in the second terminal area have different signal arrangements.

4. The electro-optical panel according to claim 1 , wherein

the at least one of wires extending from between the first terminal area and the second terminal area is connected to both of a terminal arranged in the first terminal area and a terminal arranged in the second terminal area.

5. The electro-optical panel according to claim 3 , wherein

the at least one of wires extending from between the first terminal area and the second terminal area is connected to any one of a terminal arranged in the first terminal area and a terminal arranged in the second terminal area.

6. The electro-optical panel according to claim 1 , wherein

the terminal group arranged in the first terminal area and the terminal group arranged in the second terminal area include a power supply terminal to which a predetermined potential is applied,

the at least one of wires extending from between the first terminal area and the second terminal area is a power supply wire which is connected to the power supply terminal,

among power supply terminals included in the terminal group arranged in the first terminal area and the terminal group arranged in the second terminal area, a number of common power supply terminals to which a common potential is applied is larger than a number of power supply terminals to which another potential is applied.

7. The electro-optical panel according to claim 6 , wherein

a common power supply wire connected to a common power supply terminal has a portion having a wire width larger than another power supply wire connected to another power supply terminal.

8. An electro-optical device using the electro-optical panel according to claim 1 .

9. An electro-optical device using the electro-optical panel according to claim 2 .

10. An electro-optical device using the electro-optical panel according to claim 3 .

11. An electro-optical device using the electro-optical panel according to claim 4 .

12. An electro-optical device using the electro-optical panel according to claim 5 .

13. An electro-optical device using the electro-optical panel according to claim 6 .

14. An electro-optical device using the electro-optical panel according to claim 7 .

15. An electronic apparatus using the electro-optical device according to claim 8 .

16. An electro-optical panel, comprising:

a driving circuit in a circuit area;

a first terminal in a first terminal area, the first terminal area being arranged outside of the circuit area;

a second terminal in a second terminal area, the first terminal area being arranged between the circuit area and the second terminal area in a first direction viewed from the circuit area;

a plurality of terminals which are arranged in the first terminal area in a second direction different from the first direction; and

a wire from the second terminal which is connected to the driving circuit through an area outside of the first terminal area in the first direction.

17. The electro-optical panel according to claim 16 , further comprising:

a wire from the first terminal which is extend from between the first terminal area and the second terminal area and is connected to the driving circuit through an area outside of the first terminal area in the first direction.

18. The electro-optical panel according to claim 16 , wherein,

the wire from the second terminal is connected to a common power supply terminal and is thicker than that of the other wire from the first terminal.
