Abstract: An array substrate and a liquid crystal display device adopt a four-domain electrode structure and have advantages of improving the gradient of a V-T curve and contrast, achieving ideal response time, and the like. The array substrate comprises gate lines, data lines and pixel units defined by the gate lines and the data lines. Pixel electrodes (10) and common electrodes (11) arranged on the same layer are formed in the pixel units. Both the common electrodes (11) and the pixel electrodes (10) adopt a comb structure, and comb teeth of the common electrodes (11) and comb teeth of the pixel electrodes (10) are alternately arranged. Each comb tooth of the comb structure is divided into an upper comb tooth (13) and a lower comb tooth (14) in different directions by a node (12). All the upper comb teeth (13) are parallel to each other, and all the lower comb teeth (14) are parallel to each other. For a pixel electrode (10) and a common electrode (11) that are neighboring each other, a spacing (151) between two upper comb teeth (13) is unequal to a spacing (152) between two lower comb teeth (14).

Abstract: A dry-toner type coloured particle display ( fig. 13 ) is disclosed. In the image display panel, two or more groups of particles (103) having different colours and different charging characteristics are sealed in the space between two substrates (101,102), at least one of which is transparent. The particles move through the space in response to an applied electrostatic field produced by a pair of electrodes arranged on the substrates in order to display an image. Surface texture parameters R a (average roughness) and S m (usually an average peak to peak distance between neighbouring asperities on a surface) of the bounding substrates lie within specified ranges, defined relative to the particle size, in order to weaken attractive forces between the particles and the surface of the respective substrate. These attractive forces can be adhesion forces such as intermolecular and electrostatic image charge forces (as well as others), and are reduced by decreasing the effective particle to substrate contact area. As a result, the particles are more easily removed and the display driving voltage is reduced.
Further display arrangements include the provision of bumps, dips or micro-cutouts on part of a substrate electrode to create a lateral electric field component, which again weakens attractive forces between the particles and the substrate electrode. Additionally, there is an arrangement disclosed in which an insulating member having a volume resistivity ρ of not less than 1 x 10 12 Ω.cm is coated thinly on to the surface of the substrate with which the particles are in contact in order to prevent leakage of charge away from the particles to the substrate.
Finally, there is an arrangement in which the display state of the image can be read-out by detecting the current due to the particles when these are moved inside a pixel.

Abstract: A liquid crystal display device, wherein a liquid crystal layer held between a lower substrate (1) and an upper substrate (2) comprises crossed columns (15), a wall surface structure (17), and a seal member (13). The columns (15) are disposed at four sides of each of pixels. The pixels adjacent to each other are connected to each other through openings (27) between the columns (15). The wall surface structure (17) is formed around the columns (15) arranged in a lattice shape. The columns (15) and the wall surface structure (17) are formed on a same member with adhesiveness, and simultaneously formed by patterning using photolithography. A part of the wall surface structure (17) forms a liquid crystal filler port (14). The seal member (13) is installed on the outer periphery of the wall surface structure (17). A liquid crystal filled from the filler port (14) is filled into all pixels through the openings (27). Since the openings between the columns (15) are always brought into a lit state, a lattice-like black matrix (6) covering the upper side of all columns (15) is formed on the upper substrate (2).
