Abstract

An electro-optical device includes, on a substrate, three sub-pixels, three sampling switches, three data lines, three image signal lines, and three lead wiring lines. The three sub-pixels correspond to red, green and blue, respectively. The three sub-pixels are included in a unit pixel. The three sampling switches correspond to the three sub-pixels, respectively. The three data lines electrically connect the three sub-pixels and the three sampling switches with each other, respectively. The three image signal lines, which are provided on a side opposite to the three sub-pixels with respect to the three sampling switches, correspond to the three sampling switches, respectively. The three lead wiring lines electrically connect the three sampling switches and the three image signal lines with each other, respectively. Among the three sampling switches, a sampling switch corresponding to green is disposed close to the three image signal lines compared to other two sampling switches.

Claims (21)

1. An electro-optical device, comprising:

three sub-pixels respectively corresponding to red, green and blue, the three sub-pixels included in a unit pixel;

three sampling switches respectively corresponding to the three sub-pixels;

three data lines respectively electrically connecting the three sub-pixels and the three sampling switches with each other;

three image signal lines provided on a side opposite to the three sub-pixels with respect to the three sampling switches, the three image signal lines respectively corresponding to the three sampling switches; and

three lead wiring lines respectively electrically connecting the three sampling switches and the three image signal lines with each other;

wherein, among the three sampling switches, a sampling switch corresponding to the green is disposed close to the three image signal lines compared to other two sampling switches.

2. The electro-optical device according to claim 1 , wherein, among the three sampling switches, a sampling switch corresponding to the blue is disposed so as to be distant from the image signal lines compared to a sampling switch corresponding to the red.

3. The electro-optical device according to claim 1 , wherein the three sampling switches each include a plurality of sampling switches, and are arranged in one direction intersecting the other direction along which the three data lines are arranged, and arranged so as to be displaced from one another in the other direction.

4. The electro-optical device according to claim 1 , wherein, among the three lead wiring lines, a lead wiring line corresponding to one of the three image signal lines is electrically connected to the corresponding one of the three image signal lines, the lead wiring line including a plurality of lead wiring lines.

5. The electro-optical device according to claim 1 , further comprising a plurality of external circuit connection terminals,

wherein the three image signal lines are electrically connected respectively to the plurality of external circuit connection terminals on a side on which the three image signal lines are not connected to the three lead wiring lines.

6. The electro-optical device according to claim 5 , further comprising a peripheral driving circuit provided so as to overlap a position of linearly connecting the plurality of external circuit connection terminals and the three sampling switches with each other,

wherein the three image signal lines are provided so as to detour the peripheral driving circuit.

7. An electronic apparatus comprising the electro-optical device according to claim 1 .

8. An electro-optical device, comprising:

a plurality of sub pixels, the plurality of sub pixels including a red sub pixel for displaying a red image data, a green sub pixel for displaying a green image data, and a blue sub pixel for displaying a blue image data;

a plurality of sampling switches, the plurality of sampling switches including a first sampling switch for switching a red image data signal to the red sub pixel, a second sampling switch for switching a green image data signal to the green sub pixel, and a third sampling switch for switching a blue image signal to the blue sub pixel; and

a plurality of image signal wirings, the plurality of image signal wirings including a first image signal wiring that is electrically connected to the first sampling switch, a second image signal wiring that is electrically connected to the second sampling switch, and a third image signal wiring that is electrically connected to the third sampling switch,

the plurality of sampling switches being disposed between the plurality of sub pixels and the plurality of image signal wirings,

the second sampling switch being disposed closer to the plurality of image signal wirings than the first sampling switch and the third sampling switch.
