Abstract: Pixel electrode fabricating processes are remarkably reduced. A pixel electrode 22 is formed without using any vacuum film forming apparatus by employing a sol-gel material and coating an insulating substrate with the sol-gel material by a spin-coating method or a dipping method, and this allows the fabricating processes to be reduced. During this course, by forming the pixel electrode before the formation of a scanning electrode 23, signal wiring lines and a TFT 24, the electrode wiring and the TFT 24 suffer no thermal damage even if they have a heat resistance temperature of about 350° C. Furthermore, by using a sol-gel material having photosensitivity, patterning processes are reduced by the elimination of the photoresist patterning process and the etching process. An investment for the equipment of a fabricating apparatus can thus be reduced to allow the cost reduction of the active matrix substrate itself to be achieved.

Then, the terminal device will accept designation input for designating a print data processing procedure, thereafter sending to the print server processing data representative of contents of the designated print data processing procedure.

Abstract: An object of the invention is to provide a liquid crystal display apparatus driving method capable of preventing display quality deterioration caused by action of DC voltage components exerted on a liquid crystal layer. Common electrode potential set at counter potential K5 for correcting a first DC voltage component &Dgr;V1 ascribable to parasitic capacitance of TFT is shifted to correction potential K6 for correcting a second DC voltage component &Dgr;V2 ascribable to characteristics of each substrate. Since the second DC voltage component &Dgr;V2 ascribable to difference in characteristics between the substrates and the first DC voltage component &Dgr;V1 ascribable to parasitic capacitance are corrected beforehand, the DC voltage component acting upon the liquid crystal layer is kept as small as possible, thereby preventing an image persistence or the like, so that the reliability of the liquid crystal display apparatus improves.

Abstract: On an optical disc including a substrate on which pits having at least two different depths are formed, main information is recorded by the shape of the pits and additional information is recorded by the depth of the pit. It is possible to reverse polarity of a tangential push-pull signal dependent on the depth of the pit, and therefore it becomes possible to record information utilizing the depth of the pit. This improves recording density of the optical disc. Further, when information of the optical disc is to be copied, the information recorded by the depth of the pit cannot be copied. Therefore, unauthorized reproduction can be prevented.
