Abstract
In a device for displaying images by application of an electric field to a charged substance, a structure for reducing afterimages and a method for manufacturing the structure are provided. The device is a display device which includes a plurality of pixel electrodes and a charged layer (a layer including a charged substance) provided over the pixel electrodes. An end of one of two pixel electrodes that are adjacent to each other among the plurality of pixel electrodes has a depression in an end-face direction, and an end of the other of the pixel electrodes has a projection in the end-face direction. In a state in which the depression and the projection are in a set, a gap is formed between the two pixel electrodes.
