Abstract
An electric field driving device, in which a plurality of pixels, each of which is 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, includes pixel electrodes, a common electrode, an insulating layer, and a material. Each of the pixel electrodes is formed in correspondence with the sub-pixel on the substrate. The common electrode is formed above the pixel electrodes on the substrate so that at least part of the common electrode overlaps each of the pixel electrodes in plan view. The insulating layer is formed on the substrate between the pixel electrodes and the common electrode. The material 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 common electrode has a plurality of slits that at least partly overlap the pixel electrodes in plan view. At least a portion of the slits are respectively provided continuously over a plurality of the sub-pixels. Each of the sub-pixels corresponding to the same color includes the same numbers of end portions of the plurality of slits.
