Abstract

PURPOSE:To keep the interval between electrodes regular while using flexible electrode substrates by cutting seal-bonded substrates along lines drawn along the outsides of the seal-bonded parts. CONSTITUTION:Flexible substrates 4, 5 are seal-bonded together with an adhe sive 3 of a prescribed shape so that upper electrodes confront properly lower electrodes, and the seal-bonded substrates 4, 5 are cut along lines 1, 2 drawn along the outsides of seal-bonded parts to obtain plural cells.

Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a method for manufacturing a display such as liquid crystal, electroluminescence, electrochromic, etc. using a flexible substrate.

TECHNICAL BACKGROUND In recent years, proposals have been made for the use of display devices in various fields using display materials such as liquid crystal, electrochromic, and electroluminescent displays using flexible electrode substrates.

However, even if an attempt is made to construct a display body using a flexible substrate, problems such as discontinuing the spacing between the electrode substrates enclosing the display medium during cutting tend to occur, making it impossible to construct a single display body with good display quality.

OBJECTIVES> An object of the present invention is to eliminate such drawbacks and to manufacture a display such as a liquid crystal that does not disturb the electrode spacing while using a flexible electrode substrate.

<Summary of the Invention> The method for manufacturing a display body of the present invention uses a flexible substrate,
After sealing the upper and lower electrodes with adhesive in a predetermined shape so that they face each other vertically correctly, the substrates of the display body are cut and divided into a plurality of cells. The sealing portion is characterized in that the sealing portion is cut and divided by performing a cutting process such as a shirring process along the planned cutting lines along both outer sides of the sealed portion on each of the surfaces facing the outside.

<Example> Figure 1 shows an example of the present invention, in which 1 and 2 are cutting lines, 8 is an epoxy-based, urethane-based, silicone-based adhesive, etc., and 4 is a polyester film, a polyimide film, a phenoxy-based adhesive, etc. A flexible upper substrate such as a film, and 5 a lower substrate.

To shirring this, shirring M/
Attach to C.

The cutting process for shearing is shown in Figure 2. That is, a cell in which the upper substrate 5 and the lower substrate 4 are joined is placed on the floor plate 7 and cut by the cutter 6. During shearing, the cutting edge of the cutter 6 hits the cell surface obliquely, and the cells are sequentially cut from the end.

After cutting, it is separated into individual cells as shown in FIG. Third
As is clear from the figure, #'i after cutting into multiple pieces etc.
, the cut surface is compressed and never widens, and the cell gap of the upper substrate is maintained.

FIG. 4 shows another embodiment of the invention. FIG. 4 shows a method of cutting by punching. In other words, a substrate on which a plurality of liquid crystal displays are formed is placed on a lower die (die X) 13, and punched using an upper die (punch) 11. 5. In addition, 14 is a cutting blade side holder. Even in this manner, cutting can be performed.

FIG. 6 is an explanatory view of a mechanism for pulling and cutting while pressing a blade such as a knife, and constitutes another embodiment of the present invention. That is, a substrate on which a plurality of liquid crystal displays 12 are formed is placed on a floor plate 15 with grooves formed along cutting lines, and cut by pressing a cutting blade side holder 14 equipped with a blade against it. In addition to providing the blades along a plurality of cutting lines, there is also a method of cutting one cutting line and then moving the blades to cut other parts.

In the single liquid crystal display 16 cut in this way, care must be taken because the distance between the substrates at the junction between the upper electrode substrate 17 and the lower electrode substrate 18 near the cut portion may not be maintained at a predetermined distance. Even in such a case, the cell thickness of the liquid crystal section can be maintained at a predetermined distance by keeping the distance from the liquid crystal filling part to the cutting part at 2 mm or more.

Note that in the above embodiments, the cut portion may be the sealing material portion instead of the portion where the seal is cut.

Further, in the above examples, the shirring process caused the least amount of sagging or burrs, and the spacing between the substrates was kept uniform.

The flexible substrate of the present invention is polyester (polyethylene terephthalate), Fe/-? It refers to plastic film substrates such as polyurethane, urethane, and epoxy.Furthermore, in liquid crystal displays, a plastic polarizing plate may also serve as the substrate.

Effects> As described above, according to the manufacturing method of the present invention, it is possible to maintain a predetermined interval between the electrodes in the enclosed portion of the display medium during cutting, while using a flexible substrate.
