摘要:
Inventions 1-3 relate to an image display unit provided with an image display plate for displaying an image formed by sealing at least two kinds of particles different in color and charging characteristic between two substrates, at least one of them being transparent, and imparting an electric field to particles from electrode pair consisting of electrodes provided on a substrate to move particles flying. In the first invention, fine recesses and/or fine protrusions (25) are provided on part of or whole of the surface of an electrode, or fine notched holes are provided on part of or whole of the surface of an electrode. In the second invention, the particle-contacting surface of a substrate is coated with a thin-film insulator having a volume resistivity of at least 1 × 1012 [Ω⋅cm] to provide a insulator thin film, or the arithmetic average roughness (Ra) and the unevenness average interval (Sm) of a particle-contacting substrate surface respectively satisfy specified expressions. In the third invention, a fly-moving current produced when particles in a pixel are moved flying is detected to thereby read an image display status.

Further, in the third aspect of the invention, an image display state is read-out by detecting a fly/move current produced when the particles are flown and moved in a pixel.
摘要:
An image display device includes an image display panel for displaying an image as follows. Cells isolated from one another by partitions are formed between two opposing substrates, at least one of which is transparent. Image display media are enclosed in the cells and an electric field is applied to the image display media so as to move the image display media, thereby displaying an image. [1] The partitions are formed by the photolithographic method and the partition shape is formed in a tapered shape having an end width of the rear surface substrate side greater than the end width of the front surface substrate side. [3-1] A plurality of cells are formed so as not to correspond by 1 : 1 with the pixel positions for displaying an image. [3-2] The ratio of the cell area/pixel area is set to be smaller than 4. [2] The image display panel is manufactured as follows. A first layer composed of photo-sensitive colored composition is formed on one of the substrates. A second layer composed of photo-sensitive composition having a higher light transmittance and a greater thickness than the first layer is formed on the first layer. The first layer and the second layer on the substrate are subjected to exposure via a mask and then developed and washed. Thus, colored partitions are formed on the substrate and the other substrate is attached to the colored partitions.
