Abstract:
1. An electric field driving device in which a plurality of pixels, each of the plurality of pixels being formed of two or more sub-pixels that respectively correspond to different colors from one another, are arranged in a matrix in a pixel region on a substrate, comprising: a plurality of pixel electrodes, each of the plurality of pixel electrodes being formed in correspondence with the sub-pixels on the substrate; a common electrode that is formed above the plurality of pixel electrodes on the substrate so that at least part of the common electrode overlaps each of the plurality of pixel electrodes in plan view, and has a plurality of slits; an insulating layer that is formed on the substrate between the plurality of pixel electrodes and the common electrode; and a material that is driven by an electric field that is generated on the basis of a difference in electric potential between each of the pixel electrodes and the common electrode, the plurality of slits at least partly overlap each of the plurality of pixel electrodes in plan view, at least a portion of the plurality of slits in each of the sub-pixels being parallel to one another and including a continuous portion that extends in a straight line over the plurality of sub-pixels that are included in one pixel of the pixels and arranged adjacent to one another, and an extending direction in which the continuous portion that is included in the one pixel extends and an extending direction in which the continuous portion that is included in at least one of the plurality of pixels arranged adjacent to the one pixel extends being different from each other.
