The present invention relates to a display device, and more particularly to a conductive glass substrate type electronic paper display device.

Electrophoretic display (EPD) is a new display device developed by recent display technology, and is currently mostly used in electronic paper, electronic books, electronic billboards, and electronic tags. The electrophoretic display device is a reflective display device, that is, the electrophoretic display device uses light reflection to present an image, and thus, compared with the currently-used Thin Film Transistor Liquid Crystal Display (TFT LCD), electrophoresis The display device displays an image without a backlight.

Referring to FIG. 1 , there is shown a conventional electronic paper device 10 which uses a electrophoresis principle to drive a charged coloring particle by an electric field to produce a color contrast display, which comprises a driving substrate 11 and an electronic paper body 12, and an electronic device. The paper body 12 is disposed on the drive substrate 11. The driving substrate 11 has a patterned pixel electrode layer 111 and a lower substrate 112. The electronic paper 12 includes an upper substrate 121, a transparent electrode layer 122, an electrophoretic material 123 and an adhesive layer 124. The electrophoretic material 123 is sealed between the upper substrate 121 and the adhesive layer 124, and includes a plurality of charged dye particles C1 and a dielectric solution L1. In addition, the transparent electrode layer 122 is formed on the upper substrate 121 On one side, the transparent electrode layer 122 is disposed opposite to the pixel electrode layer 111.

By applying a voltage difference between the pixel electrode layer 111 and the transparent electrode layer 122, the charged dyed particles C1 are moved toward the pixel electrode layer 111 or the transparent electrode layer 122 having a polarity opposite to that of the dyed particles C1, and The electrode layers 111 and 122 selectively apply a voltage to determine the color of the dielectric solution L1 or the charged dyed particles C1, and change the color to be developed by applying a reverse voltage.

It should be noted that the pixel electrode layer 111 of the electronic paper device 10 is mainly used for displaying a full color pattern. For the purpose of achieving full color, a color filter is formed on the electronic paper body 12, and a color filter is formed. The alignment step with the driving substrate 11 causes the patterns of the color filters to be aligned with the pixel electrode layer 111 on the driving substrate 11 to achieve full color display.

However, when the aforementioned electronic paper device 10 is applied to a display device that requires only a monochrome display of a character type or a pattern or the like, it will require a more complicated electrophoretic material processing step or need to accurately align the colors. The filter and the drive substrate 11 increase the unnecessary manufacturing cost of the electronic paper device 10, and how to provide a "conductive glass substrate type electronic paper display device" having an effect and simplifying the production to reduce the manufacturing cost.
