Embodiment Construction

[0141] For an embodiment of the present invention, according to Figure 1 to Figure 9 The description is as follows, but the present invention is not limited thereto. First, the configuration of the manufacturing system (liquid crystal display device manufacturing system) of this embodiment will be described below. The manufacturing system includes the bonding device of the present invention.

[0142] figure 1 is a sectional view showing the manufacturing system. As shown in the figure, the manufacturing system 100 has a two-stage structure, 1F (1st floor) part is the film conveyance mechanism 50, and 2F (2nd floor) is the bonding apparatus 60 including the board|substrate conveyance mechanism.

[0143]

[0144] First, the film transport mechanism 50 will be described. The film conveying mechanism 50 unwinds the polarizing film (polarizing plate) and conveys it to the nip rollers 6, 6a and 16, 16a, and plays a role of winding up an unnecessary release film. On the othe...

Abstract

Disclosed is an application device that includes a first substrate conveyor mechanism that conveys a substrate (5) such that the latitudinal sides thereof are along the conveyance direction, a nip roll that applies a polarizing film upon the lower face of the substrate (5), an inverter mechanism that inverts the substrate (5) and positions the substrate (5) upon a second substrate conveyor mechanism, the second substrate conveyor mechanism that conveys the substrate (5) such that the longitudinal sides thereof are along the conveyance direction, and a nip roll that applies a polarizing film upon the lower face of the substrate (5) on the second substrate conveyor mechanism. The first substrate conveyor mechanism and the second substrate conveyor mechanism face in the same direction, and positions the substrate (5) on the second substrate conveyor mechanism in a manner such that the substrate (5) (1) describes a curve, (2) is inverted, and (3) is aligned so that the long sides in the direction of conveyance of the first substrate conveyor mechanism are orthogonal to the conveyance direction.

Description

technical field [0001] The present invention relates to a laminating device of a polarizing film and a manufacturing system of a liquid crystal display device provided with the laminating device. Background technique [0002] Conventionally, liquid crystal display devices have been widely manufactured. A polarizing film is usually attached to a substrate (liquid crystal panel) used in a liquid crystal display device to control transmission or blocking of light. The polarizing films were attached so that their absorption axes were orthogonal. [0003] As a method of bonding a polarizing film to a substrate, a so-called chip-to-panel method (chip to panel method) in which a polarizing film is cut into a size suitable for the substrate and then bonded is exemplified. However, in this method, since the polarizing films are bonded to the substrate one by one, there is a disadvantage of low productivity. On the other hand, as another method, a so-called roll-to-panel method (ro...
