Manufacturing method for liquid crystal display

摘要

A manufacturing method for a liquid crystal display panel includes the steps of slitting a first optical film which includes a polarizing film having an absorption axis in its width direction, the polarizing film including a polyvinyl alcohol-based resin film containing a dichromatic substance and has an Nz coefficient of 1.10 or more, and rolling the slit first optical film in its width direction; slitting a second optical film, which includes a polarizing film having an absorption axis in its longitudinal direction, and rolling the slit second optical film in its width direction; bonding the cut first optical film onto one surface of the liquid crystal cell; and bonding the cut second optical film onto another surface of the liquid crystal cell.

1. A manufacturing method for a liquid crystal display panel including a liquid crystal cell and optical films arranged on both sides of the liquid crystal cell,
the manufacturing method comprising the steps of: cutting, while feeding a first optical film from an optical film roll, the optical film roll being obtained by slitting the first optical film having an elongate shape, which includes a polarizing film having an absorption axis in its width direction, the polarizing film including a polyvinyl alcohol-based resin film that contains a dichromatic substance and has an Nz coefficient of 1.10 or more, so as to have a width corresponding to a pair of opposing sides of the liquid crystal cell, and by rolling the slit first optical film, the first optical film in its width direction so as to have a length corresponding to another pair of opposing sides of the liquid crystal cell; cutting, while feeding a second optical film from an optical film roll, the optical film roll being obtained by slitting the second optical film having an elongate shape, which includes a polarizing film having an absorption axis in its longitudinal direction, so as to have a width corresponding to a pair of opposing sides of the liquid crystal cell, and by rolling the slit second optical film, the second optical film in its width direction so as to have a length corresponding to another pair of opposing sides of the liquid crystal cell; bonding the cut first optical film onto one surface of the liquid crystal cell; and bonding the cut second optical film onto another surface of the liquid crystal cell.
