Abstract

An electrooptic device includes two adjacent pixel electrodes. A potential that is different from the potential of the first and second pixel electrodes is applied to an area between the adjacent pixel electrodes.

Claims (17)

1. An electrooptic device comprising:

a plurality of image signal lines;

a plurality of scanning lines arranged in an array with the plurality of image signal lines and intersecting with the plurality of image signal lines at locations corresponding to pixels;

a first substrate and a second substrate;

an electrooptic material sandwiched between the first and second substrates;

a first pixel electrode and a second pixel electrode located between the electrooptic material and the first substrate, the first pixel electrode and the second pixel electrode separated by a region extending between the first pixel electrode and the second pixel electrode, the first and second pixel electrodes being supplied with different potentials;

a conducting layer formed in an island shape on the first substrate, the conducting layer overlapping the region extending between the first pixel electrode and the second pixel electrode, and formed on the same layer as the first pixel electrode and the second pixel electrode; and

a connecting portion that electrically connects an image signal line of the plurality of image signal lines and the conducting layer, and wherein the image signal line feeds image signals to the first pixel electrode and is formed on the first substrate and under the conducting layer.

2. The electrooptic device according to claim 1 , further comprising:

a counter electrode formed on the second substrate and facing the first pixel electrode and the second pixel electrode.

3. The electrooptic device according to claim 2 , wherein

the respective potentials of the first pixel electrode and the second pixel electrode have different polarities with reference to the common potential.

4. The electrooptic device according to claim 1 , wherein

the first pixel electrode and the second pixel electrode are formed on the same layer in such a manner as to increase in the interval therebetween so that the width of part of the region is increased.

5. An electronic device comprising the electrooptic device according to claim 1 .

6. The electrooptic device according to claim 1 , wherein the electrooptic device further includes a pixel-switching TFT serving as a switching element for the first pixel electrode, and wherein the image signal line is electrically connected to a source of the TFT, the first pixel electrode is electrically connected to a drain of the TFT, and a scanning line of the plurality of scanning lines is electrically connected to a gate of the TFT.

7. The electrooptic device according to claim 1 , wherein the image signal lines extend in a direction on the electrooptic device that is orthogonal to the scanning lines.
