A liquid crystal display device comprises a pair of substrates each provided with a transparent electrode, and a ferroelectric liquid crystal disposed therebetween. One of the substrates has thereon a homogeneous alignment, and the other substrate has thereon a tilted alignment film for aligning liquid crystal molecules in contact therewith in a tilted direction with respect to the face thereof. The combination of the two-types of alignment films provides a monodomain of uniformly aligned ferroelectric liquid crystal molecules, which leads to an improved display characteristic including increased contrast.

An electrooptical display device having, between a pair of electrode plates, a layer of a guest-host, dichroic dye-containing nematic liquid crystal having a positive dielectric anisotropy, wherein optical characteristics of the section of the liquid crystal layer laid between a pair of electrodes formed separately on the electrode plates are made substantially equal, when no voltage is applied between the electrodes, to optical characteristics of the other section of the liquid crystal layer corresponding to the background, thereby providing a good positive display, that is, the formation of a colored display pattern distinctly discernible on a colorless or light-colored background.

An electromechanical transducer includes a first electromagnetic element and a second electromagnetic element, such as electrodes, disposed opposite to each other with a sealed cavity therebetween. The sealed cavity is formed by removing a sacrifice layer and then performing sealing. A sealing portion is formed by superposing a film of a hardened second sealing material that has fluidity at normal temperature on a film of a first sealing material that does not have fluidity at normal temperature.

A highly uniform flow is provided to an object to be processed, while a processing apparatus is downsized, to remove particles efficiently. The processing apparatus includes a processing bath having a liquid injection port in the bottom thereof, a rectifier plate located between the bottom of the processing bath and a position at which an object to be processed is positioned, and a distribution portion extending between the rectifier plate and the liquid injection port and over the liquid injection port. The distribution portion includes an opposing portion opposing the liquid injection port, a surrounding portion surrounding a space between the opposing portion and liquid injection port, and a guard portion or extended portion extending outwardly from the bottom end of the surrounding portion.

A liquid crystal device, comprising: a pair of substrates each provided with an electrode including one substrate having thereon a color filter and a coating layer, and a liquid crystal layer comprising a chiral smectic liquid crystal disposed together with spacer beads between the pair of substrates, wherein the liquid crystal layer has a thickness smaller than a diameter of the spacer beads and a maximum thickness of the coating layer, the coating layer having a pencil hardness of at most 7 H. The above layer structure between the substrates is effective in improving resistance to external shock and providing a uniform cell gap.

A display device includes a multiplicity of pixels arranged in a matrix of rows and columns, each pixel including a plurality of color pixels each divided into a plurality of sub-color pixels having mutually different areas. The plurality of sub-color pixels are arranged in the row or column direction in different manners for at least two of said plurality of color pixels. As a result, the sub-color pixels may be arranged so that, when the respective color pixels are driven to display an identical gradation level, a ratio of a row-direction line width to a column-direction line width is closer to 1 than the ratio obtained when all the color pixels have an identical sub-color pixel arrangement, whereby numerals and characters, for example, can be displayed at an improved display quality.
摘要:
A liquid crystal device is constituted by a pair of oppositely spaced substrate each having on its opposite surface a group of stripe electrodes disposed to intersect with those disposed on the other substrate, and a liquid crystal disposed between the substrates so as to be driven by a voltage applied through the stripe electrodes. The group of stripe electrodes on at least one of the pair of substrates are formed through a lithographic step including dividing the stripe electrodes into at least two divisions at a line parallel (or perpendicular) to the extension of the stripe electrodes, and repeating a pattern exposure for each division of the stripe electrodes so as to dispose a joint between the divisions of the stripe electrodes at a non-display part including a spacing between two stripe electrode on the same substrate (or at a part in alignment with a non-display part including a spacing between two stripe electrodes on the opposite substrate). In an embodiment, the liquid crystal device is provided with a dummy electrode pattern for promoting the liquid crystal injection.
摘要:
An electrode plate with a color filter having a good planarity and suitable for a liquid crystal device is provided by forming on a transparent substrate a porous electroconductive film colored in a prescribed pattern by impregnation with an organic colorant. After being further coated with an insulating film and an alignment film, the electrode plate with a color filter may be applied to another electrode plate with a spacer therebetween to form a cell, which is then filled with a liquid crystal to form a liquid crystal device.
