Manufacturing system of optical display device and manufacturing method

Abstract

A manufacturing system of an optical display device of the present invention is a manufacturing system of an optical display device that bonds an optical material to an optical display component and is provided with a primary bonding device that bonds a first surface of a plurality of optical display components to the primary optical material sheet while unwinding a band-shaped primary optical sheet from a primary whole roll where the sheet has a larger width than the width of the display region of an optical display component in the width direction of the component perpendicular to the transport direction of the optical display components for a plurality of optical display components transported on a line; a primary cutting device that cuts out a primary optical bonding body that includes a single optical display component and the primary optical material overlapping the single optical display component from a bonding sheet by cutting the part opposite the primary optical component sheet facing the display region and the remaining part positioned on the outside of the opposite part, and cuts out the primary optical material as the optical material having a size corresponding to the display region from the primary optical component sheet; and a secondary bonding device that bonds secondary optical parts to the second surfaces of the optical display components in the bonding part of the primary optical bonding material while transporting the plurality of secondary optical materials with a separator sheet as the carrier after the band-shaped secondary optical component sheet having a width corresponding to the display region in the width direction of a component for a plurality of bonding bodies of primary optical parts transported on the line is wound out together with the separator sheet from the secondary whole roll; cutting is performed along the width direction each time the secondary optical component sheet is unrolled to the length corresponding to the display region in the secondary optical component sheet; and the secondary optical materials are formed as optical parts having sizes corresponding to that of the display region.

Description

technical field [0001] The present invention relates to a production system and production method of optical display devices such as liquid crystal displays. [0002] The present invention claims priority based on Japanese Patent Application No. 2011-262949 filed on November 30, 2011 and Japanese Patent Application No. 2011-262950 filed on November 30, 2011, the contents of which are incorporated herein. Background technique [0003] Conventionally, in the production system of optical display devices such as liquid crystal displays, optical members such as polarizers bonded to liquid crystal panels (optical display components) are cut from long films into sheets of the size corresponding to the display area of ​​the liquid crystal panel. , is packaged and transported to another production line, and then bonded to a liquid crystal panel (for example, refer to Patent Document 1). [0004] prior art literature [0005] patent documents [0006] Patent Document 1 Japanese Pat...

Problems solved by technology

[0009] Again, before the optical member is bonded to the liquid crystal panel, dust is suppressed from adhering to the liquid crystal panel by static electricity removal of the liquid crystal panel, etc., but there is also the following problem: since the bonding surface of the optical member bonded to the liquid crystal panel has Adhesive, so dust is easy to adhere to, which becomes a cause of poor bonding
