发明名称 Display device
摘要 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.

主权项 1. A display device comprising: a first substrate; a plurality of first wirings and a plurality of second wirings over the first substrate; and a plurality of pixel electrodes over the first substrate, each pixel electrode overlapping with an intersection of one of the plurality of first wirings and one of the plurality of second wirings, wherein: each of the plurality of pixel electrodes has a first end, a second end being adjacent to the first end, a third end being opposite to the first end, and a fourth end being opposite to the second end; a layer including a charged substance over the plurality of pixel electrodes; and a counter electrode over the layer including the charged substance, wherein among the plurality of pixel electrodes, first, second, and third pixel electrodes are arranged successively on one line, wherein each of the first ends of at least the second and third pixel electrodes has a projection, and each of the third ends of at least the first and second pixel electrodes has a depression, and wherein the depression of the third end of the first pixel electrode and the projection of the first end of the second pixel electrode are facing each other with a first gap interposed therebetween, and the depression of the third end of the second pixel electrode and the projection the first end of the third pixel electrode are facing each other with a second gap interposed therebetween.
