To provide a favorable porous backplane for an electro-optic display.SOLUTION: A backplane for an electro-optic display includes an electrode and a substrate. The substrate may be porous to liquids, e.g., water, and may be formed from cellulose or a similar hydrophilic polymer. The electrode is desirably also porous to the same liquid as the substrate so that the electrodes do not form liquid-impervious areas on the substrate. For example, when the liquid is water (or an aqueous solution) the electrodes may be formed from hydrophilic carbon black, which may be applied or screen-printed onto the substrate.SELECTED DRAWING: Figure 1 【課題】好適な電気光学ディスプレイのための多孔質バックプレーンを提供すること。【解決手段】電極と、基板とを含む、電気光学ディスプレイ用のバックプレーン。基板は、液体、例えば、水が浸透可能であり得、セルロースまたは類似親水性ポリマーから形成され得る。電極もまた、望ましくは、電極が基板上に液体不浸透性面積を形成しないように、基板と同一の液体が浸透可能である。例えば、液体が水（または水溶液）であるとき、電極は、基板上にコーティングされるかまたはスクリーン印刷され得る、親水性カーボンブラックから形成され得る。【選択図】図１
