Abstract

An electro-optic device includes first and second pixels that form first and second images, respectively. The first and second pixels are arranged alternately in a first direction. A light blocking element overlaps the pixels in plan view. The pixels are divided into pixel groups, each corresponding to every two pixels, which are one of the first pixels and one of the second pixels adjacent to each other in the first direction. The light blocking element has openings, each corresponding to one of the pixel groups and located in a region that overlaps the two pixels of the pixel group in plan view. Each first pixel has a light blocking region that partially intercepts light emitted from the first pixel. Each second pixel has a light blocking region that partially intercepts light emitted from the second pixel. The light blocking regions are positioned symmetrically to each other in plan view.

Claims (14)

1. An electro-optic device comprising:

a plurality of pixels at least including first pixels that form a first image and second pixels that form a second image, the first pixels and the second pixels being arranged alternately in a first direction; and

a light blocking element that overlaps the plurality of pixels in plan view,

wherein the plurality of pixels are divided into a plurality of pixel groups, each pixel group corresponding to every two pixels of the plurality of pixels, the two pixels being one of the first pixels and one of the second pixels that are adjacent to each other in the first direction,

wherein the light blocking element has openings, each opening being provided for a corresponding one of the pixel groups and located in a region that overlaps the two pixels of the pixel group in plan view, and

wherein each first pixel has a light blocking region that partially intercepts light to be emitted from the first pixel, and each second pixel has a light blocking region that partially intercepts light to be emitted from the second pixel, the light blocking regions of the first pixel and the second pixel in each pixel group being positioned symmetrically to each other in plan view.

2. The electro-optic device according to claim 1 , wherein, in plan view of the first pixels, the position of the light blocking regions in the first pixels is consistent among the pixel groups arranged in the first direction.

3. The electro-optic device according to claim 2 , wherein the first pixels and the second pixels are also arranged alternately in a second direction that is orthogonal to the first direction, and

wherein, in plan view of the first pixels, the position of the light blocking regions in the first pixels is consistent among the first pixels arranged in the second direction.

4. The electro-optic device according to claim 1 , wherein the light blocking regions in the first pixel and the second pixel in each pixel group are positioned symmetrically to each other with respect to a line between the first pixel and the second pixel in plan view.

5. The electro-optic device according to claim 1 , wherein the light blocking regions in the first pixel and the second pixel in each pixel group are positioned symmetrically to each other with respect to a point between the first pixel and the second pixel in plan view.

6. The electro-optic device according to claim 4 , wherein the light blocking regions in the first pixel and the second pixel in each pixel group overlap the corresponding opening of the light blocking element in plan view.

7. The electro-optic device according to claim 4 , wherein the light blocking regions in the first pixel and the second pixel in each pixel group are disposed outside a border of the corresponding opening of the light blocking element in plan view.

8. An electronic apparatus comprising the electro-optic device according to claim 1 as a display portion.
