Description

  The present invention relates to a method for manufacturing a liquid crystal display panel using a resin substrate.

In recent years, a liquid crystal display panel using a resin substrate instead of a glass substrate has been manufactured.
For example, like the liquid crystal display panel 10 shown in FIG. 9, the first substrate 11 and the second substrate 12 facing each other are pasted together through a sealing material 13 applied around the display region, Although not shown, a liquid crystal is sandwiched between them. Transparent electrodes are respectively formed on the opposing inner surfaces of the first substrate 11 and the second substrate 12, and at least the first substrate 11 out of the first substrate 11 and the second substrate 12 has each transparent electrode. A terminal portion 11a provided with a large number of terminal electrodes 14 connected to the electrodes is formed.

In the example shown in FIG. 9, the terminal portion 11a of the first substrate 11 is formed at a portion extending from the second substrate 12. However, like the liquid crystal display panel 10 ′ shown in FIG. In some cases, the terminal portion 11 a of the substrate 11 is formed in a portion that is recessed from the edge of the second substrate 12.
When manufacturing such a liquid crystal display panel, a first mother substrate to be a plurality of first substrates 11 and a second mother substrate to be a plurality of second substrates 12 are prepared, and each of them is prepared. The liquid crystal display panel is bonded through a sealing material that seals the liquid crystal, and the bonded first and second mother substrates are cut into a single liquid crystal display panel, and a seal is provided between the substrates of the liquid crystal display panels. The liquid crystal is injected and sealed in the gap sealed with the material.

At that time, in order to expose the terminal portion 11 a formed on the first substrate 11, it is necessary to remove a portion covering the terminal portion 11 a of the second substrate 12.
Therefore, as a method for removing an unnecessary portion of the counter substrate covering the terminal portion, for example, as described in Patent Document 1, a half-cut method and a pre-cut method have been widely adopted.
JP-A-3-33825 (FIGS. 6 and 7)

The half-cut method will be briefly described with reference to FIG.
A mother substrate 1 in which terminal portions 11a are respectively formed at one end portions of a portion to be a plurality of first substrates 11 and a mother substrate 2 to be a plurality of second substrates 12 are connected to a liquid crystal seal of each liquid crystal display panel. After bonding through the sealing material 13 applied so as to form the stopper 15, it is cut along the outer cut lines 16 and 17 of the first and second substrates 11 and 12 to provide a single liquid crystal display. Separate into panels. At that time, a half cut line 18 is formed in the mother substrate 2 in advance along the outer shape of each terminal portion 11a, and is cut halfway in the thickness direction of the substrate. After the cutting, the terminal portion 11a of the first substrate 11 is formed. The unnecessary portion 12b of the second substrate 12 covering the substrate is cut off from the half cut line 18 and removed. Then, liquid crystal is injected into each liquid crystal sealing portion 15 and sealed.

Next, the precut method will be briefly described with reference to FIG.
After the two mother substrates 1 and 2 are bonded together via the sealing material 13, they are cut along the outer shape cut lines 16 and 17 of the first and second substrates 11 and 12, and a single liquid crystal display panel It is the same as the case described above. The difference is that, before the mother substrates 1 and 2 are bonded together, the second substrate 12 is disposed on the portion of the portion that becomes the second substrate 12 that faces the terminal portion 11 a of the portion that becomes the first substrate 11. That is, a rectangular precut hole 19 longer than the width of 12 is formed. As a result, when the mother substrate is cut into a single liquid crystal display panel, the unnecessary portion 12c of the second substrate 12 between the outer cut line 16 and the precut hole 19 is automatically removed as chips. The terminal portion 11a of the first substrate 11 is exposed.

  However, in the conventional half-cut method, the terminal portion 11a of the first substrate 11 and the unnecessary portion 12b of the second substrate 12 shown in FIG. In addition, since the first and second substrates 11 and 12 are actually quite thin, they are almost attached to each other. Therefore, it is extremely workable to peel off the unnecessary portion 12b with tweezers and cut it off from the half-cut line 18. There was a problem of being bad.

  Moreover, in the conventional precut method, in the area | region used as the 2nd board | substrate 12 in the mother board | substrate 2 shown in FIG. 12, each in the area | region adjacent to the display area in the part facing the terminal part 11a of the 1st board | substrate 11, Since the precut hole 19 is formed in advance, distortion occurs around the precut hole 19 of the second substrate 12 due to heat treatment when the mother substrates 1 and 2 are bonded together, and the influence of the distortion is affected by each liquid crystal display panel. There is also a problem in that the display quality of the liquid crystal display panel after manufacture is deteriorated by spreading to the portion that becomes the display area.

  The present invention has been made in order to solve the problems in the method of manufacturing a liquid crystal display panel using such a conventional resin substrate, and an unnecessary portion of the other substrate covering the terminal portion of one substrate can be simplified. An object of the present invention is to make it possible to efficiently remove the display quality and to prevent display quality from being deteriorated by the influence of thermal distortion.

The present invention provides a liquid crystal display panel in which a liquid crystal is sandwiched between first and second resin-made substrates facing each other, and a terminal portion is formed on at least the first substrate of the first and second substrates. In order to achieve the above object, the manufacturing method includes the following steps.
(1) A step of preparing a plurality of first mother substrates to be the first substrates and a plurality of second mother substrates to be the second substrates.
(2) A step of forming precut holes in the outer regions adjacent to the portions where the terminal portions are formed in the regions to be the first substrates on the first mother substrate.
(3) A step of bonding the first mother substrate and the second mother substrate together with a sealing material.

(5) A step of forming a half cut groove from the outer surface to the middle of the thickness direction in a region of the second mother substrate to be the second substrate or a portion of the second substrate covering the terminal portion.
(In this step, the half cut groove may be formed on the mother substrate or in a single state.)
(6) The process of exposing the said terminal part of the said 1st board | substrate by cutting off the part which covers the said terminal part of the said 2nd board | substrate with a half cut groove | channel.

  A liquid crystal display panel in which the terminal portion is formed along two mutually orthogonal sides of the first substrate can also be manufactured by applying each of the above steps.

The liquid crystal is sandwiched between the first and second resin-made substrates facing each other, and the first terminal portion and the second terminal portion are formed at positions where the first and second substrates do not overlap each other. When manufacturing a liquid crystal display panel, it is preferable to have the following steps.
(1) A step of preparing a plurality of first mother substrates to be the first substrates and a plurality of second mother substrates to be the second substrates.
(2) A step of forming precut holes in the outer regions adjacent to the portions forming the first terminal portions in the regions to be the first substrates in the first mother substrate.

  In the method of manufacturing a liquid crystal display panel according to the present invention, the first and second mother substrates bonded together are cut into a single liquid crystal display panel, and then the terminal portion of the first substrate in the second substrate is covered. Cut the part with a half cut groove, but at that time, the part covering the terminal part extends longer than the terminal part by the width of the pre-cut hole, so you can easily pinch it with your fingers to expose the terminal part Work efficiency is greatly improved.

  Further, since the pre-cut hole is formed in the outer region adjacent to the portion forming each terminal portion of the mother substrate which is the substrate forming the terminal portion, it is separated from the display region of each liquid crystal display panel to be manufactured, and heat treatment Therefore, even if distortion occurs around the precut hole, the display area of each liquid crystal display panel is not affected, so that the display quality is not deteriorated.

Hereinafter, the best mode for carrying out the present invention will be specifically described with reference to the drawings.

First, as a first embodiment of the present invention, a liquid crystal is sandwiched between first and second resin-made substrates 11 and 12 facing each other as shown in FIG. An example of manufacturing the liquid crystal display panel 10 in which the terminal portion 11a having a large number of terminal electrodes 14 is formed will be described with reference to FIGS.

  FIG. 1 is a plan view of the first and second mother substrates, and FIG. 2 is a cross-sectional view along the longitudinal direction showing a state in which the first mother substrate and the second mother substrate in which the terminal portions and the precut holes are formed are bonded together. FIG. 3 is a cross-sectional view along the longitudinal direction showing a state in which a half cut groove is formed in a portion covering the terminal portion of the second substrate of the liquid crystal display panel cut into pieces. 2 is enlarged from FIG. 1, and FIG. 3 is further enlarged from FIG. In these drawings, portions corresponding to those in FIGS. 9 to 12 are denoted by the same reference numerals.

The liquid crystal display panel manufacturing method according to the first embodiment includes the following steps.

A second mother substrate 2 made of a transparent resin having a region to be the second substrate (upper substrate) 12 is prepared.

(2) Precut holes 21 are respectively formed in the outer regions adjacent to the portions of the first mother substrate 1 where the terminal portions 11a of the regions to be the plurality of first substrates 11 are formed. Before or after this step, a necessary transparent electrode is formed on the inner surface of the region to be the first substrate 11 of the first mother substrate 1 and connected to each transparent electrode at a portion where the terminal portion 11a is formed. A large number of terminal electrodes are formed. In addition, a necessary transparent electrode is also formed on the inner surface of the region to be the second substrate 12 of the second mother substrate 2.
