The present invention relates to a method of drying a coating film, and its object is to produce a coating film with small variations in thickness with stability. Thus, in the method of drying a coating film 11 formed by application of a coating solution to a long-length substrate 10 which is traveling, the coating film 11 is dried immediately after the application of a coating solution to the long-length substrate 10, with an evaporation rate of a solvent kept at 0.1 g/m2 s or less. Preferably, on a travel path of the coating film 11 immediately after coating, a plate 20 should be provided with a predetermined air gap between itself and the coating film 11 thereby to control the evaporation rate of the coating solution.

The method of cleaning a coated sheet according to the present invention is characterized in that dry wind is brown along the traveling direction of a film onto the surface of a coating layer wherein the solid content and the viscosity of the coating solution are within specified ranges. By this method, the thickness precision of the coating film can be improved in its large area, and the evenness of its in-plane optically functional property can be made even therein. The speed of the dry wind, the temperature of the wind, and the thickness of the dried coating film are preferably within specified ranges. In particular, the coated sheet is very useful as an optical material having good properties in an optically functional layer which is frequently used as a large-area coated sheet, an optical device having such an optically functional layer, an optically compensating layer, or an optically compensating plate. The coated sheet is particularly effective for an image display on which they are mounted.

The present invention provides a polarizing film having a high polarization degree and high transmittance, a process for producing the polarizing film, and a polarizing plate using the polarizing film, and an optical member. In the process for producing the polarizing film, a polyvinyl alcohol-based film is dry-stretched uniaxially, relaxed in an aqueous solution containing iodine or a dichroic dyestuff, and further stretched in an aqueous solution containing a PVA crosslinking agent. It is preferable that the polyvinyl alcohol-based film has a dry-stretch ratio of at least 2, the film after relaxation has a stretch ratio of at least 1.02, and the total stretch ratio is at most 6.5. It is also preferable that the relaxation rate is at most 10% of the dry-stretch ratio.

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.
