Abstract

A manufacturing method for a liquid crystal display panel includes slitting a first optical film having an elongate shape, to have a width corresponding to a pair of opposing sides of a liquid crystal cell, and by rolling the slit first optical film in its width direction to have a length corresponding to another pair of opposing sides of the liquid crystal cell; slitting a second optical film having an elongate shape, to have a width corresponding to a pair of opposing sides of the liquid crystal cell, and by rolling the slit second optical film in its width direction 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.
