Abstract

The invention provides an electro-optical device where a layer related to forming an image is formed with uniformity. An electro-optical device, that drives each of plural pixels individually arranged in two dimensions so as to display information, is provided with a group of pixels displaying the information within an effective display region among the plural pixels arranged in two dimensions. A group of plural pseudo-pixels that do not contribute to the display of the information are located adjacent to a group of pixels within the effective display region. A bank layer separates a pixel in the group of the plural pseudo-pixels from a pixel in the group of pixels in the effective display region, and shields light leaked from a space between pixels located adjacently each other within the effective display region.

Claims (12)

1. An electro-optical device, comprising:

a substrate;

a plurality of pixels individually arranged in two dimensions above the substrate, the plurality of pixels including a group of pixels drivable to display information within an effective display region, and a group of plural pseudo-pixels, that do not contribute to the display of information, located adjacent to the effective display region;

a pixel circuit for driving a pixel in the group of the pixels in the effective display region, a part of the pixel circuit being disposed between the substrate and a bank layer which separates a pixel in the group of plural pseudo-pixels from a pixel in the group of the pixels in the effective display region; and

a wiring in a region in which the group of plural pseudo-pixels is arranged.

2. The electro-optical device according to claim 1 , the group of plural pseudo-pixels being located at least on one side of the effective display region.

3. The electro-optical device according to claim 1 , the group of pixels within the effective display region including structural elements, at least one of the structural elements including a functional layer that is formed by an inkjet method.

4. The electro-optical device according to claim 3 , the at least one structural element formed by the inkjet method being an organic EL layer.

5. The electro-optical device according to claim 4 , the organic EL layer being made of a high polymer material.

6. An electronic apparatus, comprising:

the electro-optical device according to claim 1 .

7. The electro-optical device according to claim 1 , the shape of the group of pixels in the effective display region being almost same as the shape of the group of plural pseudo-pixels.
