Description of the Invention: [Technical Field] The present invention relates to a flat display device, and more particularly to a flat display device having electronic paper. [Prior Art] With the advent of the information age, display devices with information dissemination have become one of the indispensable electronic products for modern people due to the increasing demand for information communication with the outside world. The display device has been developed from the original cathode ray tube (CRT) display to today's thin liquid crystal display (LCD), and is widely used in communication, information and consumer electronics. Faced with the increasing demand for the effectiveness of processing and storing huge amounts of data, todayadays, relying on computer processing and rendering images through flat-panel displays. However, the size and weight of the conventional flat panel display are not as good as the convenience of carrying and convenient reading of the information recorded on the paper. Therefore, in order to maintain the portability and readability of paper, and to have the effectiveness and environmental protection of electronic product processing materials, electronic paper products using Electrophoretic Display (EPD) are compatible. Referring to Fig. 1, a conventional electronic paper device 1 utilizes an electrophoresis principle to drive a charged dye particle by an electric field to produce a color contrast display. The electronic paper device 1 includes an electronic paper body U, a drive substrate 12, and an adhesive layer 13. The electronic paper body 11 is disposed on the driving substrate 12, and the driving substrate 12 5 200837471 has a plurality of thin film transistors m and amps 122 ′ and the bismuth electrode layer 122 is formed by a thin film: The 昼 电子 electronic paper body 11 includes an upper substrate lu ～121 wei% electrophoretic material 113 and a lower substrate 114. The bright electrode layer 112 is disposed opposite to the halogen electron core layer 122, and the electrophoresis=the electric surface is h. The transparent electrode layer (1) and the lower substrate 114 are between 113 and 101, and the sub-113a is a charged particle. The tantalum dyed surface is generated when the thin film transistor 121 drives the halogen electrode layer 122 between the solar layer 122 and the transparent electrode layer 112. The voltage difference is = 沐 = = 113 113 113 113 113 113 113 113 113 113 113 113 113 113 113 113 113 113 113 113 113 113 113 113 113 113 113 113 113 113 113 113 113 113 113 113 113 113 113 113 113 113 113 113 113 113 113 113 113 113 113 113 113 113 113 122 or the transparent electrode layer 112 moves. Therefore, by selectively applying a voltage to the two plates, it is possible to determine the color of the dielectric solution = 3⁄4 layer particles 113a and then change the color by applying a reverse voltage. The electrophoretic material 113 between the two electrode layers can be charged by dyeing the particles 11; 3a 襄 2 = in the capsule by Micro-encapsulation technology. In Fig. 1, the electrophoretic substance 113 is included in the micro-cup structure as an example. Since the thin film transistor 121 of the driving substrate 12 is particularly sensitive to light in the environment, the thin film transistor i2l is exposed to light, which may cause leakage. As a result, not only the display effect of the electronic paper device 1 but also the drive substrate u is depleted in power due to leakage. Therefore, how to provide an electronic paper device capable of reducing the leakage of the 200837471 thin film transistor which drives the substrate by external light is an important subject of the present invention. In view of the above problems, it is an object of the present invention to provide an external reduction An electronic paper device in which light causes leakage of a thin film transistor of a drive substrate.

The halogen electrode layer 222 or the transparent electrode layer 212 moves. Therefore, the pressure can be selectively applied to the two electrode layers, and the color of the dielectric solution κ or the dyed particles 213a can be determined to be changed by applying a reverse voltage.

The process of driving the substrate 52 is further simplified. Therefore, it is possible to replace the passivation layer. 11 200837471 Referring to Figure 9, there is shown a cross-sectional view of an electronic paper device .6 in accordance with still another preferred embodiment of the present invention. The electronic paper device 6 includes an electronic paper body 61, a drive substrate 62, an adhesive layer 63, and a light blocking body 64. The electronic paper main body 61 and the drive substrate 62 have the same functions and technical features as those of the electronic paper main body 21 and the drive substrate 22 in the above-described embodiments, and therefore will not be described again. Here, only the light shielding body 64 will be described. In addition, the electronic paper device 6 of the present embodiment further includes a flat layer 623, and the halogen electrode layer 622 is formed on the flat layer 623. The light shielding body 64 is formed on the flat layer 623 by at least one metal layer. Since the electrode layer 622 and the light-shielding body 64 are in the same mask process, the manufacturing process can be simplified. It should be noted that the light shielding body 64 can be a plurality of metal layers, and all can be the same mask process. Further, the light shielding body 64 is made of an opaque material, so that the light penetrating through the thin film transistor 621 can be weakened. Further, the halogen electrode layer 622 can be integrated with the light shielding body 64 as a 'and formed on the flat layer 623'. Thus, the light shielding body 64 can serve as a pixel electrode layer and achieve a light shielding effect. The light shielding bodies of the above embodiments are disposed between the substrate below the electronic paper device and the substrate of the driving substrate, so that the effect of the electronic paper device is not hindered by the user, and the light damage driving through the electronic paper body can be weakened. The opportunity of the thin film transistor of the substrate can avoid the phenomenon of leakage of the thin film transistor, thereby achieving power saving and improving the use efficiency of the electronic paper device. According to the above description, an electronic paper device according to the present invention utilizes a light shielding body to shield the driving substrate, that is, the light shielding body covers the thin film transistor of the driving substrate, thereby effectively reducing the external light to the bonding film transistor. 12 200837471 In turn, the thin film transistor is protected to prevent leakage, and the power of the electronic paper device can be further saved. In addition, it is more suitable for the electronic paper device, and different shades are used. Therefore, by providing a light shielding body to protect the thin film transistor of the electronic paper device to reduce the light irradiation, the use efficiency of the electronic paper device is improved. The above is intended to be illustrative only and not limiting. Any equivalent modifications or alterations to the spirit and scope of the present invention are intended to be included in the scope of the appended claims.
