Abstract
In a first aspect of the invention, an information display panel, in which at least one group of display media having optical reflectance and charge characteristics, formed by at least one group of particles, are scaled in a cell (corresponding to one display unit) formed by partition walls between two substrates, at least one substrate being transparent, and, in which the display media, to which an electrostatic field is applied, are made to move so as to display information such as an image, includes (1) a color filter formed by arranging filters having a predetermined numbers of colors on a transparent substrate at a display side so as to perform a color display, and a black layer arranged between the partition walls and the transparent substrate. In a second and a third aspects of the invention, an information display panel, in which at least one group of display media having optical reflectance and charge characteristics, formed by at least one group of particles, are sealed in a cell (corresponding to one display unit) formed by partition walls between two substrates, at least one substrate being transparent, and, in which the display media, to which an electrostatic field is applied, are made to move so as to display information such as a color image, includes (2) transparent color filters having three primary colors respectively arranged to one cell, and a colorless transparent clear portion arranged to the respective transparent color filters, and (3) transparent color filters having three primary colors respectively arranged to three pixels formed by dividing respective display units by means of partition walls, and a colorless transparent clear portion arranged to the respective transparent color filters.
