Abstract: PROBLEM TO BE SOLVED: To eliminate the need for an offset voltage to be applied to a drive voltage by eliminating a battery effect leading to the asymmetry of liquid crystal response, to ensure a high reliability even in a long-term drive, and to enable easy manufacture without complicating the manufacturing process. SOLUTION: A conductive thin film 43 made of the same material as a confronting transparent electrode is formed, via an insulating thin film 45, on the surface of a pixel electrode 42A confronting with the transparent electrode. By providing the conductive thin film 43, the battery effect between the confronting electrodes. Thus, the asymmetry of liquid crystal response is eliminated, and the offset voltage conventionally required for the drive voltage can be dispensed with. As a result, the reliability in the long-term drive can be enhanced. Also, since the conductive thin film 43 is coated via the insulating thin film 45, the electric current between the adjacent pixel electrodes 42A is prohibited. COPYRIGHT: (C)2004,JPO

Abstract: PROBLEM TO BE SOLVED: To reduce an offset voltage applied to a drive voltage by restricting a battery effect leading to the asymmetry of liquid crystal response and to ensure a high reliability despite a long-term drive. SOLUTION: 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 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: PROBLEM TO BE SOLVED: To stably radiate electromagnetic waves having a wavelength of 400 nm or shorter with stable luminance for a long time. SOLUTION: This element is provided with an ultraviolet emission film 4 formed from a nitride of a group 3B element, and a pair of conductive films 3, 5 formed on both the surface of the ultraviolet emission film 4 in a form interposing it. The ultraviolet emission film 4 radiates an electromagnetic wave having a wavelength 400 nm or shorter by applying electric field to the pair of conductive films 3, 5. Since the nitride of a group 3B element used for the ultraviolet emission film as a base material is a chemically stable compound, the element is not deteriorated by the moisture or carbon dioxide in the atmosphere, even under a strong electric field or exposure to an ultraviolet-ray and can hence maintain stable luminance over a long time.

Abstract: PURPOSE:To enhance an efficiency of absorbing a heating light, such as a laser light, and improve a heat resistance by a method wherein a light-absorbing body absorbing a light of a specific wavelength is formed by laminating a light-absorbing layer and a light-reflecting layer on a transparent substrate. CONSTITUTION:A light-absorbing body 21 is formed by laminating a light- absorbing layer 21B of a silicon nitride layer or the like having a thickness of t1=1mum or less and a light-reflecting layer 21C of an iron layer or the like having a thickness of t2=300Angstrom or more by sputtering on a surface opposite to a light incident surface of' a transparent substrate 21A, such as a glass substrate, transmitting a light L of a wavelength of 750-900nm. In the lightabsorbing body 21, an appropriate relation of optical constants (n: refractive index, k: extinction coefficient) is held on an interface S1 between the light- absorbing layer 21B and the light-reflecting layer 21C and an interface S2 between the light-absorbing layer 21B and the transparent substrate 21A. In this manner, the incident laser light L is repeatedly reflected at the aforesaid interfaces to be trapped in the light-absorbing layer 21B, whereby an efficiency of absorbing the laser light can be raised.
