Therefore, if the optical film roll obtained in the above manner is directly supplied to the RTP system, in the RTP system, in order to separate the polarizing film 901 in the boundary area F from the product area, it is necessary to perform two and a half cuts in the width direction. , and a process of removing the polarizing film 901 in the boundary area F is also required, thus sacrificing the production tact which is an advantage of the RTP system to a large extent
In addition, the above-mentioned unnecessary film part is involved in the lamination process, and the film part needs to be removed, so foreign matter in lamination will be generated, or glue residue will be generated during removal, and the adjacent acceptable film will also change due to the glue residue. Unqualified, etc., so the yield is likely to decrease

Embodiment approach 1
[0062] Figure 1~3 It is a schematic diagram of the continuous manufacturing system of the optical display panel concerning Embodiment 1. Below, refer to Figure 1~3 The continuous manufacturing system of the optical display panel which concerns on this embodiment is demonstrated concretely.
[0063] In addition, in this embodiment, the liquid crystal cell of horizontally long rectangle is mentioned as an optical cell, and the liquid crystal display panel of horizontally long rectangle is mentioned as an example of an optical display panel, and it demonstrates. As an optical film roll, use figure 1 , figure 2 , image 3 Roll of optical film shown. That is, as the first optical film roll 1, a roll formed by winding a belt-shaped first laminated optical film 10 by laminating the first carrier film 12 along the The strip-shaped first polarizing film 11 (corresponding to the first optical film) having an absorption axis in the longitudinal direction has a width correspondi...

Abstract
This manufacturing method involves: a first bonding step in which a first polarizing film is supplied from a first optical film roll and, while optical cells are conveyed, is bonded to the visible surface of the optical cells along the supply direction of the first polarizing film from a pair of opposite sides of the optical cell; and a second bonding step in which a second optical film is removed and supplied from a storage unit storing the second optical film in sheet form, and, while the optical cells are conveyed, is bonded to the back surface of the optical cells along the supply direction of the second film either from the aforementioned pair of opposite sides of the optical cell, or from another pair of opposite sides.
Description
[0001] This application is a divisional application of the patent application with the application number 2013800540840, the application date is October 28, 2013, and the invention name is a continuous manufacturing method for optical display panels and a continuous manufacturing system for optical display panels. technical field [0002] The invention relates to a manufacturing method of an optical display panel and a manufacturing system of an optical display panel. Background technique [0003] A continuous manufacturing method (so-called roll-to-panel (RTP: Roll to Panel) system) of a liquid crystal display panel is disclosed in which a belt-shaped first polarizing film having an absorption axis along the longitudinal direction is fed out from a first optical film roll. The first polarizing film obtained by cutting the strip-shaped first polarizing film in the width direction is bonded to the back surface of the liquid crystal cell, and the film is released from the secon...
