AI Technical Summary
Technical Problem
The adhesive layer in conventional backplanes for electronic paper displays has insufficient withstand voltage, leading to potential leakage in pixel electrodes, especially when high voltages are applied, and is prone to leakage due to conductive foreign matter.
Method used
Incorporating an insulating layer with higher resistance than the adhesive layer between the pixel electrodes and the adhesive layer, and ensuring the insulating layer covers the pixel electrodes and the space between them, thereby preventing direct contact with conductive foreign matter.
Benefits of technology
Suppresses pixel electrode leakage, enhancing display quality by maintaining insulation even under high voltage conditions and preventing foreign matter contact.

Abstract
Suppresses leakage from pixel electrodes. [Solution] The backplane 11 is a backplane to which an adhesive layer 31, which is arranged on one main surface of the display layer 30 for displaying an image, is bonded, and comprises a pixel electrode 13 arranged between the display layer 30 and the adhesive layer 31, and an insulating layer 22 interposed between the pixel electrode 13 and the adhesive layer 31.
