Electric field driving display device

Abstract

It is an object to provide an electric field driving display device capable of displaying a high quality image and to provide an electric field driving display device in which residual images in an outline of a pixel is prevented from occurring. An insulating film is formed over a second electrode and a plurality of first electrodes are provided over the insulating film. Each of the first electrodes is electrically connected to the second electrode. The second electrode is provided to partly overlap a region between the adjacent two first electrodes. In other words, viewing the top and the bottom of the display device, the adjacent first electrodes are provided apart from each other and the second electrode is provided to embed a space between the adjacent first electrodes.
