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.

Claims

1. A display device comprising:

a plurality of pixel electrodes; and

a layer including a charged substance, the layer provided over the plurality of pixel electrodes,

wherein at least one end of two pixel electrodes adjacent to each other among the plurality of pixel electrodes includes a curved portion in an end-face direction.
