摘要： A system and a method for manufacturing a liquid crystal display element through a reduced number of steps are provided, in which a liquid crystal panel is turned over, by means of a panel turning mechanism, about an axis not parallel to any of the long and short sides of the liquid crystal panel so that the positional relationship between the long and short sides of the liquid crystal panel can be reversed, after one of sheet pieces of optical functional films is bonded to the liquid crystal panel and before another of the sheet pieces is bonded thereto, which can achieve the same effect by a single operation as in the case where turning over the liquid crystal panel and rotating it are performed independently.

摘要： The present invention provides a method and apparatus designed to, during continuous manufacture of liquid crystal display panels, feed only a normal sheet to a lamination position for lamination to a rectangular panel and continuously laminate them together while positionally aligning them with each other. In the present invention, plural devices making up the entire apparatus are cooperatively associated with each other to make it possible that, among plural polarizing film sheets comprising a defect-free normal sheet and a defect-containing defective sheet each formed on a carrier film comprised in a strip-shaped film laminate. The normal sheet is reliably peeled from the carrier film by cooperatively associating feeding of the strip-shaped film laminate with a normal-sheet peeling device, and the defective sheet is reliably taken up while being attached to the carrier film, by cooperatively associating the feeding of the strip-shaped film laminate with a defective-sheet path changing device.

摘要： An object of the invention is to provide a method and a system for manufacturing a liquid crystal panel, which allow more successful bonding of an optical film to a liquid crystal cell. A pressing force Fa per unit area applied when the optical film is pressed by the first roller and a pressing force Fb per unit area applied when the liquid crystal cell is pressed by the second roller satisfy the relation Fa>Fb. On the first roller side, the feed may fail to be stabilized due to the influence of tension fluctuations or vibration acting on the first optical film, so that air bubbles may occur. When the second roller side, where such an influence does not occur, contributes more to the feed of the liquid crystal cell, the liquid crystal cell can be successfully fed in the process of bonding the optical film thereto.

摘要： A polarizing plate with optical compensation layers that performs a wide viewing angle compensation with respect to a liquid crystal cell, allows circularly polarized light to be obtained over a wide range of light wavelengths, contributes to the reduction in thickness, prevents thermal irregularity from occurring, and can effectively prevent light leakage from occurring in a black display. The polarizing plate includes a polarizer, a first optical compensation layer, and a second optical compensation layer that are stacked together in this order. The first optical compensation layer is formed of a liquid crystal compound and has a relationship of nx>ny=nz and an in-plane retardation Re1 of 100 to 170 nm. The second optical compensation layer has a relationship of nx=ny>nz and a thickness direction retardation Rth2 of 30 to 400 nm. The angle formed between the absorption axis of the polarizer and the slow axis of the first optical compensation layer is in the range of “plus” or “minus” 25 to 65 degrees.
