Title:
PRODUCTION METHOD FOR IAMGE DISPLAY UNIT AND IMAGE DISPLAY UNIT
Document Type and Number:
WIPO Patent Application WO/2004/079442
Kind Code:
A1
Abstract:
A production method for an image display unit in which a particle group or a powder/particle material is sealed between two facing substrates at least one of which is transparent, and an electric field is generated between the substrates to move particles or a powder/particle material and hence display an image, and which comprises a plurality of display cells sectioned by partitions, wherein, when a particle group or a powder/particle material is sealed into cells sectioned by partitions between substrates, a mask is set on a partition upper surface (first invention). In addition, a production method for an image display unit provided with an image displaying panel in which a particle group or a powder/particle material is sealed between a transparent substrate and a counter substrate, and an electric field is given to a particle group or a powder/particle material to move particles or a powder/particle material and hence display an image, and which has at least one image display element separated by partitions from each other, the method comprising the steps of forming a partition on one substrate out of the transparent substrate and the counter substrate, filling a particle group or a powder/particle material into a space constituting an image display element separated by a partition, removing unnecessary particle group or powder/particle material left on a partition, screen-printing an adhesive in a position, facing a partition, on the surface of the other substrate out of the transparent substrate and the counter substrate, and joining a partition with the other substrate via an adhesive to thereby obtain an image display panel (first embodiment of a second invention).
