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 (18)

1. An electro-optical device, comprising:

a plurality of pixels individually arranged in two dimensions, the plurality of pixels including a soup of 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; and

a bank layer consisting of one layer, and separating adjacent pixels of the plurality of pixels from each other, and shielding light leaked from a space between pixels located adjacently each other within the effective display region.

2. An electro-optical device, comprising:

a plurality of pixels individually arranged in two dimensions, the plurality of pixels including a group of 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, each pixel and pseudo-pixel having a liquid-philic control layer that is liquid-philic processed; and

a bank layer separating a pixel in the group of plural pseudo-pixels from a pixel in the group of the pixels in the effective display region, and shielding light leaked from a space between pixels located adjacently each other within the effective display region.

3. The electro-optical device according to claim 2 , further comprising a pixel circuit corresponding to each of the pixels in the effective display region.

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

5 .The electro-optical device according to claim 2 , 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.

6. The electro-optical device according to claim 5 , the at least one structural element formed by the inkjet method being an organic EL layer.

7. The electro-optical device according to claim 6 , the organic EL layer being made of a high polymer material.

8. The electro-optical device according to claim 6 , further comprising a liquid-philic control layer having affinity toward liquid material used in the inkjet method, which is located adjacent to the functional layer.

9. The electro-optical device according to claim 5 , at least uniformity of the functional layer being examinable by using at least one of the group of pseudo-pixels.

10. The electro-optical device according to claim 9 , the examination being implemented by irradiating examination light onto the at least one pseudo-pixel and detecting optical luminescence thereby.

11. The electro-optical device according to claim 2 , further comprising a circuit arrangement region where a circuit is arranged at the lower part of a region defined by the group of the pseudo-pixels.

12. The electro-optical device according to claim 11 , the circuit arrangement region being usable as an arrangement location region where a circuit is not related to driving pseudo-pixels.

13. An electronic apparatus, comprising:

the electro-optical device according to claim 2 .
