Problems solved by technology

[0009] However, it is difficult for a transparent resin film to completely block moisture like a glass substrate. Even if the upper substrate and the lower substrate made of a transparent resin film are airtight with an adhesive material, as in Patent Document 1, the It is difficult to completely seal moisture, and a small amount of moisture may still enter between the two sealed substrates
Also, even if a moisture-proof material (desiccant) is enclosed, the amount of moisture that can be handled is limited
In short, in a substrate made of a flexible material such as a transparent resin film, it is difficult to completely airtight the inside and eliminate the influence of humidity on the organic TFT.

Embodiment approach

[0097] In addition, the above-mentioned embodiment can also be implemented as follows, for example.

[0098] • In the above-described embodiment, the bias voltage BG is applied to the back gate electrode 40 , but the bias voltage BG may be applied to the scan signals SC1 to SCn as long as it is within the withstand voltage range of the organic transistor Tr. In this case, the back gate electrode of the organic transistor Tr can be omitted.

[0099] - In the above embodiment, the rear substrate 15, the transparent substrate 17, the inner surface sealing material 31, the surface sealing material 32, etc. constituting the electrophoretic display device 10 are flexible. However, it is not limited thereto, and at least some of the materials may not have flexibility.

[0100] In the above embodiment, the display panel 11 is sealed by the sealing material 30 in air with an air temperature of 20°C and a relative humidity of 0.9%, that is, air with a moisture content of 0.18 g / m3 or l...

Description

technical field [0001] The present invention relates to a driving method of an organic transistor and an electrophoretic display device. Background technique [0002] In recent years, non-light-emitting display devices having a flexible structure have been adopted as display devices used in devices requiring flexibility, such as electronic paper. As one of such non-emissive display devices, there is an electrophoretic display device utilizing an electrophoretic phenomenon. Here, the electrophoretic phenomenon is a phenomenon in which fine particles (electrophoretic particles) migrate due to Coulomb force when an electric field is applied in a dispersant in which fine particles (electrophoretic particles) are dispersed in a liquid (dispersion medium). [0003] The electrophoretic display device is driven by changing the potential between electrodes facing each other across the electrophoretic particles by driving the thin film transistor and generating an electric field betw...
