Patent ID: 7362485

Claim:
An image display medium comprising: a display layer including a display region whose display state changes by electrical action; a pair of substrates that retain the display layer therebetween, with at least part of the pair of substrates configuring a frame portion to which an electrical connection connector for electrical connection to the outside connects, and with at least one of the pair of substrates being transparent; a first scan electrode group that is a group of electrodes disposed across the overall display region along a column direction of the display region on the surface of one of the pair of substrates facing the display layer; a second scan electrode group that is a group of electrodes disposed across the overall display region along a row direction of the display region on the surface of the other of the pair of substrates facing the display layer; a first electrical contact group disposed at a place on the pair of substrates to which the electrical connection connector connects; a second electrical contact group disposed at a place on the pair of substrates to which the electrical connection connector connects; a first connection wire group that electrically connects the first electrical contact group and the first scan electrode group to each other; and a second connection wire group that electrically connects the second electrical contact group and the second scan electrode group to each other, wherein the first electrical contact group and the second electrical contact group are disposed apart from each other a distance that is greater than the distance between two mutually adjacent contacts belonging to the first electrical contact group or the second electrical contact group along at least one of a thickness direction and a surface direction of the pair of substrates.
