[0199] Such as Figure 21 As shown, the first embodiment is an example of a layout in which the third electrode 59 in a linear form is arranged on the transparent pixel electrode substrate and surrounds all the effective pixels on the side of the transparent pixel electrode 52. The third electrode 59 is connected to the third electrode extraction portions 60, 61, 62, and 63. Such as Figure 22 As shown, an insulating layer 58 perpendicular to the transparent pixel electrode 52 is formed. Such as Figure 23 As shown, a third electrode 59 is formed on the insulating layer 58 on the portion where the third electrode 59 is placed. As described above, when the third electrode surrounds all effective pixels, the open ratio can be increased, so that an electrodeposition type display device with good light extraction efficiency can be constructed.

[0201] Such as Figure 24 As shown, the second embodiment has linear top and bottom third electrodes 59 arranged on the transparent pixel electrode substrate in a direction parallel to the stripe structure of the transparent pixel electrode 52, so that all effective pixels are located An example of the layout between the two third electrodes. The top and bottom third electrodes 59 are respectively connected to the take-out portions 60, 61 and 62, 63 of the third electrode. Such as Figure 25 As shown, an insulating layer 58 perpendicular to the transparent pixel electrode 52 is formed. As described above, when the top and bottom third electrodes are configured such that all effective pixels are placed between the two third electrodes, the open ratio can be increased, which can constitute an electrodeposition type display device with good light extraction efficiency.

[0203] Such as Figure 26 As shown, in the third embodiment, the right and left third electrodes 59 in the form of a straight line are arranged on the transparent pixel electrode substrate in a direction perpendicular to the stripe structure of the transparent pixel electrode 52, so that all are effective. An example of a layout in which pixels are located between the right and left third electrodes. The right and left third electrodes 59 are connected to the third electrode extraction portions 60, 63 and 61, 62, respectively. Such as Figure 27 As shown, an insulating layer 58 perpendicular to the transparent pixel electrode 52 is formed. Such as Figure 28 As shown, the third electrode 59 is formed on the insulating layer 58 on the portion where the third electrode 59 is placed. As mentioned above, when the two third electrodes are placed so that all effective pixels are located between the right and left third electrodes, the open ratio can be increased, which can constitute an...
