Description

本発明は、繰返し書き換えが可能な画像表示媒体およびその製造方法に関し、特に、接着剤に起因する濃度むらや表示欠陥のない画像表示媒体およびその製造方法に関する。 The present invention relates to an image display medium and a manufacturing method thereof capable of repeatedly rewriting, in particular, the image display medium and a manufacturing method thereof relating to no density unevenness and display defects caused by the adhesive.

書き換えが可能な従来の画像表示媒体として、トナーを用いたものが知られている(例えば、特許文献1参照。) As a conventional image display medium capable of rewriting, one using a toner are known (e.g., see Patent Document 1.)

この画像表示媒体は、表面基板部材上に形成された列電極を誘電体膜により保護した透光性を有する表面基板と、背面基板部材上に形成された行電極を誘電体膜により保護した背面基板と、表面基板と背面基板とを対向させて保持するとともに、基板間の空間を基板と平行な方向に仕切って複数のセルを形成する仕切り部材と、各セルに封入され、負に帯電した白色粒子、およびトナーからなる正に帯電した黒色粒子とを備える。 The image display medium, and the surface a light-transmitting substrate that the formed column electrodes protected by a dielectric film on the surface the substrate member, the row electrodes formed on the rear substrate member was protected by a dielectric film back a substrate holds the surface substrate and the rear substrate are opposed, and the partition member to form a plurality of cells partition the space between the substrates in the direction parallel to the substrate, is enclosed in each cell, the negatively charged comprising white particles, and a toner and a positively charged black particles.

この画像表示媒体は、背面基板上にインクによるスクリーン印刷と加熱焼成処理を複数回行って所望の高さの仕切り部材を形成し、仕切り部材の開口部への粒子の収容、および仕切り部材の先端へのエポキシ樹脂等の接着剤の塗布を行った後、表面基板と仕切り部材とを接着剤を介して当接して位置合わせし、接着剤を固化して仕切り部材と表面基板とを貼り合わせることにより形成される。 The image display medium, a plurality of times the heating and firing processes as screen printing with ink on the back substrate to form a partition member having a desired height, accommodation of the particles into the openings of the partition member, and the partition member tip after application of the adhesive such as an epoxy resin to, the surface substrate and the partition member via the adhesive aligned contacts, to bonding the partition member and the surface substrate by solidifying the adhesive formed by.

このように構成された画像表示媒体において、行電極と列電極との間に直流電圧を印加すると、電極間に電界が形成され、電界の向きに応じて白色粒子,黒色粒子が表面基板または背面基板側へ移動し、表面基板の内側に付着した白色粒子と黒色粒子とのコントラストにより表面基板を通して画像表示を行う。 In the thus constructed image display medium, when a DC voltage is applied between the row and column electrodes, an electric field is formed between the electrodes, the white particles, black particles surface substrate or back according to the direction of the electric field Go to the substrate side, image display is performed through the surface substrate by the contrast between the white particles and black particles adhering to the inner surface the substrate. この構成によれば、電気泳動や磁気泳動を用いた画像表示媒体のように液体を必要としないため、コントラストの高い画像を得ることができる。 According to this arrangement, because it does not require the liquid to the image display medium using the electrophoretic and magnetophoretic, it is possible to obtain a high-contrast image.
