[0010]

In order to solve the above-mentioned problems, the present invention provides the following display panel manufacturing method and apparatus. (1) Method and apparatus for manufacturing first type display panel (1-1) Method for manufacturing display panel This is a method for manufacturing a display panel by stacking panel elements for forming a display panel for displaying an image. A step of aligning and holding the first panel element on the first stage, a step of aligning and holding the second panel element on the second stage, and surfaces of the first and second panel elements to be bonded to each other Providing an adhesive on at least one of the surfaces, and moving at least one of the first stage holding the first panel element and the second stage holding the second panel element so that both panel elements face each other. A step of superposing predetermined end portions of both panel elements on each other, and holding the panel elements in the superposed state; Method of manufacturing a display panel sequentially comprising a bonding step will stuck to fully Te.

In the step of bonding both panel elements in this display panel manufacturing method, for example, a pressing member for pressing both panel elements is used on the first stage, and the first panel element is kept pressed by the pressing member while the first panel element is being pressed. This may be performed by moving the stage relative to the pressing member.

In this case, the pressing member may also serve as a means for pressing and holding, for example, the ends of the two panel elements superimposed on the first stage. Of course, the end holding means for performing the holding step may be provided separately from the pressing member.

In any case, the pressing member may have a panel element pressing surface having a convex curved surface, and the panel element pressing surface may be rolled relatively to the panel element in the bonding step. Thereby, the bonding step can be performed smoothly.

A representative example of a pressing member having a panel element pressing surface having a convex curved surface is a pressing roller having a circular cross section, but a pressing member having a fan-shaped panel element pressing surface as viewed from the side can also be used. When a pressing roller having a circular cross section is used, a so-called inverted crown type pressing roller having a central portion smaller in diameter than both end portions may be used so that the panel element does not wrinkle due to pressing by the pressing roller.

The following method can be exemplified as a method of manufacturing a display panel using a pressing member. That is, at least one of the first stage holding the first panel element and the second stage holding the second panel element is moved to make the two panel elements face each other, and the predetermined ends of the two panel elements are overlapped with each other, In the holding step of holding the two panel elements in the overlapping state, the holding of the overlapping end portions of the two panel elements is pressed against the first stage by a pressing member so as to be held in the overlapping state. In the bonding step of sequentially bonding the entire surface with the adhesive from the end held in the bonded state, the first stage in which both panel element ends are pressed by the pressing member is connected to the pressing member. , While the panel element is being pressed by the first stage, the second panel element is moved relative to the pressing member and the second stage, and the first panel element is pulled out of the second stage. A method of manufacturing a display panel will bonding the two panels elements above the sequence entirely in the adhesive.

In this method, when a pressing member having a panel element pressing surface made of a convex curved surface is adopted, the panel element pressing surface can be rolled relative to the panel element in the bonding step. Thereby, both panel elements can be bonded smoothly.

In any case, in the step of holding the second panel element on the second stage, a predetermined end where the first and second panel elements are overlapped, which is a subsequent step, is brought into the overlapped state. In order to easily carry out the step of holding, the predetermined end portions of the two panel elements are overlapped with each other, and the second panel element end when holding in the overlapped state is set to the second end.
You may hold | maintain on the said 2nd stage in the state protruded from the stage.

In any of the above display panel manufacturing methods, the holding of the first and second panel elements by the first and second stages is not limited thereto, but a typical example is an intake hole provided in the stage. And the case where the panel element is sucked and held through the device.

In any of the above manufacturing methods, the mutual alignment of the first and second panel elements can be performed by various methods. For example, it can be performed by using a substrate or panel alignment method which is known per se.

The following method can be exemplified as a method of positioning.

First, in a state where the first and second panel elements are accurately aligned, an alignment mark positioned so that a later-described holding step and a bonding step of an overlapping end portion of both panel elements are performed. The first and second stages should be provided in advance, and the first panel element should have the alignment mark that should match the first stage alignment mark, and the second panel element should have the alignment mark that should match the second stage alignment mark. An alignment mark is provided in advance. Then, (a1) a corresponding panel element is arranged on each stage, and the panel element is manually moved and aligned while visually observing the alignment mark between the stage and the panel element or using a camera. Alternatively, (b1) a corresponding panel element is arranged on or above each stage, and the panel element is moved by an XY-θ driving device and aligned while observing the alignment mark between the stage and the panel element with a camera. When a panel element is arranged and aligned above the stage, the panel element may be placed on the stage after the alignment.

Alternatively, the following method can be exemplified. That is,
The stage is provided with a panel element holding portion capable of XY-θ driving, the holding portion holds a panel element provided with a positioning mark in advance, and the alignment mark of the panel element is observed with a camera. The positioning of the panel elements is performed by moving the holding unit with an XY-θ driving device. In this case, the positioning of the panel elements is performed such that the later-described holding step and bonding step of the overlapped ends of the two panel elements are performed in a state where the first and second panel elements are accurately positioned. .

In any case, the alignment by the XY-θ driving device may be performed by manually operating the XY-θ driving device, but the mark information detected by the camera (for example, the position information Etc.) to control the operation of the XY-θ driving device so as to align the panel elements. In the latter case, an image processing method for positioning a substrate, a panel, or the like can be used.

It is needless to say that an XY-θ driving device is a device that can move an object in a direction X, a direction Y perpendicular thereto, and rotate the object about an axis perpendicular to the XY plane. .

The alignment mark may emit light upon energization as a liquid crystal mark, an electroluminescence mark, or the like.

The step of providing an adhesive on at least one of the surfaces of the first and second panel elements to be bonded to each other includes bonding the element to the panel element surface in advance and covering the surface with a protective sheet. Removing the protective sheet from the peeled double-sided adhesive sheet (the sheet may be tape-shaped) to expose the adhesive surface, and applying the adhesive to the panel element surface manually or by an adhesive application device. Can be illustrated. The method of providing the adhesive is arbitrary as long as there is no problem. In the case of providing by application, at least one of the two panel elements may be applied over the entire surface, but it is disposed at the bonding start end of at least one of the panel elements or another appropriate part and is bonded. You may make it expand between both panel elements as it progresses.

The step of providing the adhesive is performed before the predetermined ends of both panel elements are overlapped. As long as there is no problem, it may be carried out at any stage as long as it is before the end overlapping.

When there are three or more panel elements to be laminated, for the third and subsequent panel elements, the bonded panel element obtained in the bonding step is regarded as the first panel element, and One panel element to be bonded is regarded as the second panel element, and the above-described steps are substantially repeated, so that the next panel element may be bonded to the already bonded panel elements one by one.
