A liquid crystal display comprises a liquid crystal display panel, the liquid crystal display panel comprising a first substrate; a second substrate disposed on an observer side with respect to the first substrate and opposed to the first substrate; a liquid crystal held between the first substrate and the second substrate; an upper polarizing plate disposed on the observer side with respect to the second substrate; and a resin film disposed on the observer side with respect to the upper polarizing plate and affixed in contact with the upper polarizing plate, the resin film being higher in surface hardness than the upper polarizing plate. Both reduction in thickness of the liquid crystal display panel and ensuring of a sufficient strength are attained.

By using carbon fibers having a fineness of 25,000 deniers or more, the present invention provides a carbon fiber package including a cheese winding package or a coreless package in which an outside diameter of the package, a diameter of a bobbin or an inside diameter of the package, and a winding width are regulated in the specific ranges, a square-end type package in which a yarn width per fineness, wind angles at the start of winding and at the end of winding, and shifting of the yarn are regulated in the specific ranges, and a carbon fiber packed member in which an average bulk density is regulated in a specific range. Those carbon fiber packages and the carbon fiber packed member solve troubles and inconveniences during use, and also packages which have a high winding density and which do not break easily can be obtained.

A controllable microscopic bubble nucleation in fluid polymer material production method and its apparatus that utilizes a gas pipe disposed in the conveyance screw shaft of a conventional injection or extraction forming mechanism and, furthermore, a microbubble generating component (such as a microscopic perforation vented metal head or a microscopic perforation ceramic head, etc.) installed at the front extremity of the conveyance screw shaft. At the rear extremity of the gas pipe, a pressurization pump or a high pressure gas storage tank is admitted from an air intake opening, enabling the gas to be indirectly heated by an electric heater on the materials pipe. The high temperature gas is thereafter outputted from the microscopic perforations of the microbubble generating component such that high temperature microscopic bubbles are directly admitted into the section of liquid polymer material which is then uniformly amalgamated by the conveyance screw shaft and then deposited into a forming die. As a result, high pressure gas conveyance or termination is controllable; control is afforded as to whether each section of liquid polymer material is microbubble nucleated and amalgamated. The present invention thereby provides a microbubble nucleation production method in which the non-bubble nucleated is at the surface and the bubble nucleated is at the interior section when the liquid polymer material is poured into a forming die.

A liquid display device of D-STN mode capable of suppressing a line-shaped ununiformity of brightness in displaying a dark appearance is presented. A displaying cell 1 and a compensation cell 21 are formed so that there is a difference of thickness of at least 0.05 mm between the thickness of a glass substrate 2 at a front side of the displaying cell 1 and the thickness of a glass substrate at a rear side of the compensation cell 21. The displaying cell 1 and the compensation cell 21 are arranged between a first polarizing plate 32 and a second polarizing plate 33. A backlight 31 is of a type emitting light whose half value width with respect to the peak luminance is at least 5 nm.

A polishing method able to easily flatten unevenness formed on the surface of a film to be polished and able to efficiently polish the film flat while suppressing damage to an interlayer insulating film below the film, comprising, when polishing an object having a film such as an interconnection layer formed burying interconnection grooves formed in an insulating film of a substrate, supplying a polishing solution over the surface to be polished at least substantially parallel to the surface to preferentially remove by polishing the projecting portions of the film and flatten the surface by the shear stress of the processing solution or arranging a cathode member facing the surface and supplying an electrolytic solution containing a chelating agent between the surface and cathode member while supplying voltage between the film and the cathode member to preferentially remove by polishing the projecting portions of the film and flatten the surface by the shear stress of the electrolytic solution, and a polishing apparatus using the same.

A liquid crystal display includes a liquid crystal display panel having a first substrate, a second substrate disposed on an observer side with respect to the first substrate and opposed to the first substrate, a liquid crystal held between the first substrate and the second substrate, an upper polarizing plate disposed on the observer side with respect to the second substrate, and a resin film disposed on the observer side with respect to the upper polarizing plate and affixed in contact with the upper polarizing plate. The resin film is higher in surface hardness than the upper polarizing plate and has a surface hardness of at least 3H in terms of surface pencil hardness. Each of the first and second substrates have a thickness of no greater than 0.5 mm, and a total thickness of the liquid crystal display panel is no greater than 2 mm.
