    Abstract: A reflection type liquid crystal display element and a liquid crystal display unit which can eliminate or minimize a defective orientation specific to a vertically-oriented liquid crystal that is caused by a pixel groove structure, and implement a high contrast and a good image quality. A reflection type pixel electrode (42) has an inclined shape on its outer periphery , and form a diverging trapezoidal shape with its electrode width gradually increasing from the upper to lower sides. With the side surfaces of the pixel electrode (42) inclined to eliminate verticality within a section, liquid crystal molecules oriented horizontally can be eliminated at an electrode end in a pixel groove portion. Even if an orientation is locally disturbed slightly in a horizontal direction, a mutual action with surrounding vertically-oriented liquid crystal molecules can provide a sufficient verticality even in a pixel groove portion.

    Abstract: A production method capable of efficiently producing a display device of higher image quality; and a production device applicable to such production method. Positioning is effected such that a seal pattern (4) formed on at least one of the lower and upper substrates (2, 7) to extend along the outer edges of a plurality of display panels (1) coincides with a raised pattern (27, 29) formed on at least one of the pair of parallel surfaces (19S, 20S) in lower and upper platens (19, 20) and having a planar shape corresponding to the seal pattern (4), the lower and upper platens (19, 20) being used to press the lower and upper substrates (2, 7) in a Z-direction. Thus, a gap in an effective image surface region (3) between the lower and upper substrates (2, 7) can be made more uniform, making it possible to efficiently produce a display device of higher image quality.

    Abstract: A battery effect leading to the asymmetry of liquid crystal response is restricted, an offset voltage applied to a drive voltage can be reduced, and a high reliability is ensured despite a long−term drive. A dissimilar metal film (43) opposite in standard electrode potential sign to a metal material constituting a pixel electrode is spread over the pixel electrode; a battery effect between facing electrodes is restricted in comparison to a conventional element not covered with the dissimilar metal film (43). Accordingly, the asymmetry of liquid crystal response can be restricted, and an offset voltage required for a drive voltage can be reduced in comparison to a conventional one. Therefore, a circuit for applying an offset voltage is simplified or eliminated, and a long−term reliability at driving can be enhanced.

    Abstract: The transmittance of liquid crystal becomes easily saturable at a voltage of up to 5-6 V by regulating the Δn value of a homeotropic liquid crystal material to as large as 0.1 or larger despite the thickness, of a homeotropic liquid crystal layer, of as small as 2 μm or smaller, thereby permitting drive at a practically low voltage and significantly improving transmittance itself. Accordingly, it is possible to implement a reflection type homeotropic liquid crystal device having a sufficient transmittance and low-voltage drive characteristics and being excellent in high-speed response, and a display unit and projection optical and display systems using this device.

    Abstract: A battery effect causing asymmetry in liquid crystal responses can be prevented, an offset voltage applied to a driving voltage can be reduced, and high reliability is secured even during long term driving. A pixel electrode is covered with a metal film (43) which has a standard electrode potential with a sign opposite to that of a metallic material constituting the pixel electrode. This prevents the battery effect between the opposing electrodes, unlike conventional devices which do not have the metal film (43). Thereby, the asymmetry in the liquid crystal responses can be prevented and reducing the offset voltage which is required for the driving voltage can be accomplished unlike the conventional ones. Moreover, a circuit for applying the offset voltage is simplified or unnecessary, and improvement of long term reliability during the driving can be accomplished.
