The present invention relates to a liquid crystal display panel, and more particularly to a technology for narrowing the frame of a liquid crystal display panel.

The liquid crystal display panel is, for example, a TFT substrate provided with a plurality of thin film transistors (hereinafter referred to as “TFT”) and a TFT substrate, and is disposed so as to face the TFT substrate. CF substrate) provided with a common electrode or the like, a liquid crystal layer provided between the TFT substrate and the CF substrate, and an alignment provided on each surface of the TFT substrate and the CF substrate on the liquid crystal layer side. The film and a TFT substrate and a CF substrate are adhered to each other, and a sealing material provided in a frame shape is provided between the TFT substrate and the CF substrate to enclose a liquid crystal layer. Here, the common electrode of the CF substrate is connected to, for example, a common transition electrode provided on the TFT substrate via a common transition material containing conductive particles.

For example, Patent Document 1 discloses that a first substrate and a second substrate on which electrodes and an alignment film are formed are bonded to each other, and a liquid crystal layer is sealed between them. The first conductor formed on the second substrate, the second conductor formed on the second substrate facing the first conductor, and the first conductor and the second conductor for conductive connection In a liquid crystal device provided with a vertical conduction part having a conductive material containing conductive particles, an alignment film is formed so as to cover at least one surface of the first conductor and the second conductor, and the conductive particles are A configuration in which the first conductor and the second conductor are in conductive contact through the alignment film is disclosed. According to Patent Document 1, according to this, since the conductive particles in the conductive material pierce the alignment film, the first conductor and the second conductor are made conductive. Since there is no need to form an alignment film while avoiding the above, the restriction on the outer edge position of the alignment film is eliminated.

In recent years, in liquid crystal display panels for mobile use such as mobile phones, there is a constant demand for narrowing the frame to reduce the width of the frame area around the display area in order to increase the display area for displaying images. Therefore, in a liquid crystal display panel for mobile use, when the conductive material for connecting the common transition electrode on the TFT substrate and the common electrode on the CF substrate is contained in the sealing material and used as the common transition material, the alignment film Due to manufacturing process tolerances such as printing misalignment, the end of the alignment film overlaps the portion where the sealing material is printed, and an insulating alignment film is formed between the conductive particles and the connected portion (common transition electrode and common electrode). There is a risk of being caught. If so, the connection resistance between the common transition electrode and the common electrode becomes high, and the counter potential supplied to the common electrode deviates from a predetermined value, thereby causing a display defect such as a change in color.

The present invention has been made in view of such a point, and an object of the present invention is to suppress the pinching of the alignment film between the common transition electrode and the common electrode, and to ensure the common transition electrode and the common electrode. Is to connect to.

In order to achieve the above object, according to the present invention, the common transition electrode and the extended portion of the common electrode are connected by the protruding portion of the second substrate.

Specifically, in the liquid crystal display panel according to the present invention, a terminal region is defined along at least one side, a first substrate having a common transition electrode drawn to the terminal region, and the first substrate, A second substrate having a common electrode provided so as to expose the terminal region; a liquid crystal layer provided between the first substrate and the second substrate; and the liquid crystal layer of the first substrate and the second substrate. Liquid crystal display panels each having an alignment film provided on each side surface, wherein the second substrate has a side corresponding to the side of the first substrate in which the terminal region is defined. A protrusion provided to protrude to the end of the side, the common electrode extends to the protrusion, and the common transition electrode is provided to overlap the protrusion, Conductive in the extended part of the common electrode Characterized in that it is connected via the particles.

According to the above configuration, the terminal area is defined along at least one side of the first substrate, and the side of the second substrate corresponding to the side where the terminal area is defined is the side of the first substrate. Since the protruding portion that protrudes to the end portion is provided, the protruding portion of the second substrate is disposed so as to overlap the substrate end of the first substrate in which the terminal region is defined. Therefore, it is difficult to position the alignment film on the protruding portion of the second substrate and the portion of the first substrate that overlaps the protruding portion of the second substrate. Therefore, the common transition electrode and the common electrode connected at the protruding portion of the second substrate are extended. The alignment film is prevented from being caught between the formed portions. As a result, the common transition electrode and the extended portion of the common electrode are connected to each other through the conductive particles, so that the alignment transition film is prevented from being caught between the common transition electrode and the common electrode. And the common electrode are securely connected. Further, in the liquid crystal display panel, since the protruding portion of the first substrate and the second substrate overlap at the side where the terminal region is defined, the strength of the side where the terminal region is defined is improved.

The protruding portion of the first substrate and the second substrate may be bonded to each other with an adhesive containing the conductive particles.

According to the above configuration, since the alignment film is difficult to be formed on the protruding portion of the second substrate and the portion of the first substrate that overlaps the protruding portion of the second substrate, the protruding portion of the first substrate and the second substrate contain conductive particles. Thus, the overall adhesive strength between the first substrate and the second substrate is improved.

The protrusions may be provided at both ends of the corresponding side of the second substrate.

According to said structure, since the protrusion part is arrange | positioned at the both ends in the edge | side of the 2nd board | substrate corresponding to the edge | side where the terminal area | region of the 1st board | substrate was prescribed | regulated, a pair of protrusion part of a 2nd board | substrate is 1st. By being arranged on both sides of the terminal area of the substrate, the strength of the corners of the side where the terminal area of the liquid crystal display panel is defined is improved.

The liquid crystal layer may be sealed between the first substrate and the second substrate by a sealing material containing spacer particles, and the conductive particles and the spacer particles may be formed in different sizes.

According to the above configuration, the size of the conductive particles for connecting the common transition electrode and the common electrode is different from the size of the spacer particles for defining the thickness of the liquid crystal layer. The distance between the substrates in the vicinity of the terminal region is properly maintained.

According to the present invention, since the common transition electrode and the extended portion of the common electrode are connected by the protruding portion of the second substrate, the alignment film is prevented from being sandwiched between the common transition electrode and the common electrode. Thus, the common transition electrode and the common electrode can be reliably connected.

Next, a method for manufacturing the liquid crystal display panel 50 of the present embodiment will be described with reference to FIG. Here, FIG. 6 is a plan view of the substrate before the protrusion P of the CF substrate 30 is formed. In addition, the manufacturing method of the liquid crystal display panel 50 of this embodiment includes a TFT substrate manufacturing process, a CF substrate manufacturing process, a bonding process, and a dividing process.

<TFT substrate manufacturing process>
First, after forming a metal film such as an aluminum film on the entire substrate of the insulating substrate 10a such as a glass substrate by sputtering, for example, the metal film is patterned using photolithography to obtain the gate line 1, The gate electrode and the low resistance metal layer 11 are formed to a thickness of about 200 nm.

Subsequently, for example, a silicon nitride film is formed on the entire substrate on which the gate line 1, the gate electrode, and the low-resistance metal layer 11 are formed by a plasma CVD (Chemical Vapor Deposition) method, thereby forming a gate insulating film. It is formed to a thickness of about 400 nm.

Further, an intrinsic amorphous silicon film and an n ⁺ amorphous silicon film doped with phosphorus are continuously formed on the entire substrate on which the gate insulating film is formed by plasma CVD, and then the gate is formed using photolithography. By patterning in an island shape on the electrode 11a, a semiconductor formation layer in which an intrinsic amorphous silicon layer having a thickness of about 100 nm and an n ⁺ amorphous silicon layer having a thickness of about 50 nm are stacked is formed.

Then, for example, an aluminum film and a titanium film are sequentially formed on the entire substrate on which the semiconductor formation layer has been formed by sputtering, to form a metal multilayer film, and then the metal multilayer film is formed using photolithography. By patterning, the source line 2, the source electrode, and the drain electrode are formed to a thickness of about 350 nm.

Subsequently, the n ⁺ amorphous silicon layer of the semiconductor formation layer is etched using the source electrode and the drain electrode as a mask, thereby forming a semiconductor layer and a TFT.

Further, an inorganic insulating film such as a silicon nitride film is formed to a thickness of about 300 nm by plasma CVD on the entire substrate on which the TFT is formed, and subsequently, for example, acrylic photosensitive film is formed by spin coating. An organic insulating film having a contact hole on the drain electrode and the low-resistance metal layer 11 is formed by applying a photosensitive resin or the like to a thickness of about 2 μm and exposing and developing the applied photosensitive resin through a photomask. After the formation, the inorganic insulating film exposed from the organic insulating film is etched to deepen the contact hole, thereby forming the interlayer insulating film 12.

Then, after forming a transparent conductive film such as an ITO film on the entire substrate on the interlayer insulating film 12 by sputtering, the transparent conductive film is patterned using photolithography, so that the connection terminal 5 and the common transition are formed. The electrode 13 and the pixel electrode are formed to a thickness of about 100 nm. Note that, in the lower layer of the connection terminal 5, display wirings such as the gate line 1 and the source line 2 are formed in advance by using the process of forming the gate line and the process of forming the source line. .

The TFT substrate 20 can be manufactured as described above. Thereafter, an alignment film 31a is formed on the surface of the TFT substrate 20 to a thickness of about 100 nm using a printing method.

<CF substrate manufacturing process>
First, an acrylic photosensitive resin in which fine particles such as carbon are dispersed is applied to the whole substrate of the insulating substrate 10b such as a glass substrate by a spin coating method, and the applied photosensitive resin is applied to a photomask. The black matrix 21 is formed to a thickness of about 1.0 μm by developing after being exposed to light.

Subsequently, for example, an acrylic photosensitive resin colored in red, green, or blue is applied on the substrate on which the black matrix 21 is formed, and the applied photosensitive resin is exposed through a photomask. Later, patterning is performed by developing to form a colored layer (for example, a red layer) of a selected color with a thickness of about 1.0 μm. Further, the same process is repeated for the other two colors to form other two colored layers (for example, a green layer and a blue layer) with a thickness of about 1.0 μm.

Further, after forming a transparent conductive film such as an ITO film on the substrate on which each of the colored layers is formed by sputtering, for example, the transparent conductive film is patterned using photolithography to thereby form a common electrode. 22 is formed to a thickness of about 100 nm.

The CF substrate 35 can be manufactured as described above. Thereafter, the alignment film 31b is formed to a thickness of about 100 nm on the surface of the CF substrate 35 by using a printing method. Here, as shown in FIG. 6, the CF substrate 35 is a CF substrate 30 before the unnecessary portion W is removed in a cutting step described later.

<Lamination process>
First, for example, using a dispenser, the seal material 45 contained in the spacer particles 46 is arranged in a frame shape around the display region D of the TFT substrate 20 on which the alignment film 31a is formed in the TFT substrate manufacturing process. An adhesive 47 contained in the conductive particles 48, that is, a common transition material 49 is disposed on the transition electrode 13.

Subsequently, a liquid crystal material is dropped onto a region (display region D) surrounded by the sealing material 45 on the TFT substrate 20 on which the sealing material 45 and the common transition material 49 are arranged.

Further, after the TFT substrate 20 onto which the liquid crystal material is dropped and the CF substrate 35 on which the alignment film 31b is formed in the CF substrate manufacturing process are bonded so that the display regions D overlap each other under reduced pressure, By releasing to atmospheric pressure, the outer surfaces of the TFT substrate 20 and the CF substrate 35 are pressurized to produce a bonded body.

Finally, the sealing material 45 and the common transition material 49 sandwiched between the TFT substrate 20 and the CF substrate 35 of the bonded body are cured to enclose the liquid crystal layer 40 between the TFT substrate 20 and the CF substrate 35. The conductive particles 48 are fixed between the common transition electrode 13 on the TFT substrate 20 and the extended portion of the common electrode 23 on the CF substrate 35.

<Division process>
On the surface of the CF substrate 35 of the bonded body in which the sealing material 45 and the common transition material 49 are cured in the bonding process, for example, a cutting edge of a disk-shaped cutting blade along the cutting line L as shown in FIG. While rolling the parting blade, the crack is formed and the formed crack grows in the thickness direction, thereby removing the substantially trapezoidal unnecessary portion W of the CF substrate 35. Thus, the protruding portion P (of the CF substrate 30) is formed.

As described above, the liquid crystal display panel 50 of the present embodiment can be manufactured.

Next, a specific experiment will be described.

As an example of this embodiment, conductive particles made of Sekisui Chemical Co., Ltd. micropearl AU (average particle size 4.5 μm) are used for the adhesive 47 made of acrylate-based UV curing / thermosetting resin. The liquid crystal display panel 50 was manufactured by the manufacturing method mentioned above using the common transition material 49 which mix | blended 48 weight%. In the liquid crystal display panel 50 of the present embodiment, the electrical resistance value between the pair of common transition electrodes 13 (the upper left portion and the lower left portion in FIG. 1) sandwiching the terminal region T is about 100Ω. The effect by the example was confirmed. In the conventional liquid crystal display panel in which the common transition electrode and the common electrode connected to the common transition electrode are covered with an alignment film having a thickness of about 100 nm, the electric resistance value between the corresponding pair of common transition electrodes is about 500Ω. End up.

As described above, according to the liquid crystal display panel 50 of the present embodiment, the TFT substrate 20 is defined with the terminal region T along at least one side, and the terminal region T corresponds to the defined side. Since the side of the substrate 30 is provided with a protruding portion P that protrudes to the end of the side of the TFT substrate 20, the protruding portion P of the CF substrate 30 is the substrate end of the TFT substrate 20 in which the terminal region T is defined. It is arranged to overlap. For this reason, the

alignment films

31b and 31a are not easily formed on the protrusion P of the CF substrate 30 and the portion of the TFT substrate 20 overlapping the protrusion substrate P by separating the

alignment films

31b and 31a from the necessary display region D. Therefore, the

alignment films

31 a and 31 b can be prevented from being sandwiched between the common transition electrode 13 connected at the protruding portion P of the CF substrate 30 and the extended portion of the common electrode 22. As a result, the common transition electrode 13 and the extended portion of the common electrode 22 can be connected to each other via the conductive particles 48, so that the

alignment films

31a and 31b between the common transition electrode 13 and the common electrode 22 are connected. Therefore, the common transition electrode 13 and the common electrode 22 can be reliably connected, and the frame can be narrowed. Further, in the liquid crystal display panel 50, the TFT substrate 20 and the protruding portion P of the CF substrate 30 overlap each other at the side where the terminal region T is defined, so that the strength of the side where the terminal region T is defined is improved. Can do.

Further, according to the liquid crystal display panel 50 of the present embodiment, since the

alignment films

31b and 31a are difficult to be formed on the protruding portion P of the CF substrate 30 and the portion of the TFT substrate 20 overlapping therewith, the TFT substrate 20 and the CF substrate. 30 protrusions P are firmly bonded to each other by an adhesive 47 (common transfer material 49) containing conductive particles 48, thereby improving the overall adhesive strength between the TFT substrate 20 and the CF substrate 30. Can do.

Further, according to the liquid crystal display panel 50 of the present embodiment, since the protrusions P are disposed at both ends of the side of the CF substrate 30 corresponding to the side where the terminal region T of the TFT substrate 20 is defined, the CF substrate Since the 30 pairs of protrusions P are arranged on both sides of the terminal region T of the TFT substrate 20, the strength of the corners of the side where the terminal region T of the liquid crystal display panel 50 is defined can be improved. .

Further, according to the liquid crystal display panel 50 of the present embodiment, the size of the conductive particles 48 for connecting the common transition electrode 13 and the common electrode 22 is such that the spacer particles 46 for defining the thickness of the liquid crystal layer 40. Therefore, the distance between the substrates in the vicinity of the terminal region T of the liquid crystal display panel 50 can be appropriately maintained.

In the present embodiment, the liquid crystal display panel 50 in which the terminal region T is defined on one side of the TFT substrate 20 is illustrated. However, the present invention is a liquid crystal display panel in which the terminal region is defined on two or more sides of the TFT substrate. It can also be applied to.

Further, in the present embodiment, the manufacturing method of the liquid crystal display panel 50 in which the sealing material 45 and the common transition material 49 are arranged on the TFT substrate 20 is exemplified, but the present invention places the sealing material and the common transition material on the CF substrate. The present invention can also be applied to a liquid crystal display panel manufacturing method.

Further, in the present embodiment, the method of manufacturing a liquid crystal display panel with a single surface is illustrated, but the present invention can also be applied to a method of manufacturing a liquid crystal display panel with multiple surfaces.

In the present embodiment, a method for manufacturing a liquid crystal display panel using the ODF (One Drop Drop Fill) method has been exemplified. However, the present invention provides a method for forming a blank cell under normal pressure and then performing a vacuum injection method between the blank cell substrates. The present invention can also be applied to a method for manufacturing a liquid crystal display panel in which a liquid crystal material is injected.

In this embodiment, a liquid crystal display panel including a TFT substrate having a TFT electrode connected to a pixel electrode as a drain electrode is illustrated. However, in the present invention, a TFT electrode connected to a pixel electrode is used as a source electrode. The present invention can also be applied to a liquid crystal display panel provided with a TFT substrate called.

As described above, the present invention can prevent the alignment film from being sandwiched between the common transition electrode and the common electrode and can reliably connect the common transition electrode and the common electrode. Useful for narrowing the frame.
