2. Description of the Related Art In recent years, the development of personal computers,
In particular, with the development of portable personal computers, the demand for liquid crystal display devices is rapidly increasing. This liquid crystal display device is widely used in notebook personal computers, desktop personal computers, in-vehicle navigation systems, electronic still cameras, game machines, projectors, mobile phones and the like.

In such a liquid crystal display device, usually, a pair of substrates, which are a shared electrode substrate provided with shared electrodes and a pixel electrode substrate provided with pixel electrodes, are bonded to each other through a sealing material to form a cell. Is manufactured by encapsulating a liquid crystal in the cell, and a color filter is provided to give a color to each pixel of the device.

Conventionally, a sealing material for bonding a pair of substrates is formed by printing a sealing material made of various resins such as a thermosetting resin or an ultraviolet curing resin on the surface of one substrate by a screen printing method. Was there. This screen printing method is a method in which a printing plate having grooves corresponding to the shape of the sealing material is used, the groove portion of the printing plate is filled with the sealing material, and the sealing material is transferred onto the substrate.

When the sealing material is formed by using such a screen printing method, it is inevitable that the surface of the screen mask comes into contact with the surface of the substrate, so that the dirt adhering to the screen mask can be transferred to the surface of the substrate. Is highly
In the case of being used as a liquid crystal display device, there is a problem that the display image quality is deteriorated due to the disorder of the alignment of the liquid crystal and the reliability is deteriorated. In addition to the problem of contamination, there is another problem that the screen mask comes into contact with the surface of the substrate that has been subjected to the alignment treatment, so that the alignment surface is more likely to be disturbed and the display image quality is deteriorated.

In order to solve these problems, a sealing material is applied to at least one of the inner side surfaces of the pair of substrates by using a dispenser type discharge device, and the pair of substrates is attached. A manufacturing method of a liquid crystal display device of a dispenser system adapted to be combined is disclosed (JP-A-1-200228). In this dispenser method, since the liquid crystal display device can be manufactured without contacting the orientation-treated surface, the orientation-treated surface is not contaminated and may be affected by the contact of a screen mask or the like. Therefore, it is an excellent method for producing a liquid crystal display device having a stable alignment state and high display image quality.

However, by controlling a plurality of nozzles 27 at the same time, a plurality of seals having a fine pattern can be formed. There is a problem that it is extremely difficult to form the material 108.

Further, in the formation of a black mask used in a liquid crystal display device, a pattern is usually formed by using a photolithography method or the like. In this step, a film is formed by repeating exposure, development and etching. However, there is a problem that it is necessary to form a pattern, wastes raw materials, and takes time.

The present invention has been made in view of the above problems, and when a partition member such as a sealant or a black mask is formed on a substrate, the time required for the formation can be shortened. , High-definition pattern sealing material,

It is formed by enclosing the liquid crystal L in a predetermined space defined by the surface.
The sealing material is preferably formed in the state of the mother substrate 12 (see FIG. 4) in order to improve productivity.

FIG. 5 is an explanatory view schematically showing the mother substrate 12 used in one embodiment of the liquid crystal display device of the present invention. The sealing material 108 causes an inkjet head (not shown) to scan on an area (sealing material forming area) E in which the sealing material is set, which is set in the substrate forming area 13 in the mother substrate 12, and seals the same. It is formed on the material forming area E by ejecting ink droplets from an inkjet head (not shown) and landing them. The sealing material 108 is usually the opening 11 for enclosing the liquid crystal after the pair of substrates are bonded together.
Has 0. Note that in FIG. 5, for convenience of description, the seal material forming region E before the ink droplet is landed and the seal material 108 formed after the ink droplet is landed are shown in a mixed state.

In this way, when the sealing material 108 is formed on the sealing material forming areas E set in the plurality of substrate forming areas 13 on the mother substrate 12, the material of the sealing material is an ink jet head (not shown). ), It is possible to shorten the time required for formation by ejecting the ink as ink droplets and landing the ink.

As described above, when the seal material 108 having a size of 50 mm × 70 mm is formed by using the ink jet method, it is preferable that the first ink droplet is landed on the area outside the seal material forming area E. The landing point P is preferably 100 μm or more away from the seal material forming region, and more preferably 300 μm or more. The amount (landing amount) of the ink droplets ejected from the inkjet head (not shown) tends to be unstable at the start of printing, and the amount ejected first from the inkjet head (not shown) is uneven. Ink droplets are landed on the area outside the seal material forming area E, and in the seal material forming area E, a uniform and high-definition seal material 108 with a stable landing amount.
Can be formed.

In addition, the first ink droplet is applied to the sealing material 108.
The ink may be discharged from an inkjet head (not shown) and landed on one or more projecting portions (projection forming regions) W connected to the.

The ink droplets ejected from the ink jet head (not shown) tend to be easily collected in the corner Q of the seal material forming area E, and thus the ink droplets are located outside the seal material forming area E. The ink is prevented from being unnecessarily accumulated in the corner portion Q of the seal material forming region E where the ink is likely to be unnecessarily accumulated after the ink droplet is ejected by landing the ink onto the protrusion W or the protrusion W, and the mother substrate 12 is bonded. Sometimes inside the sealing material 108 (for example, the pixel region R)
The inconvenience of protruding can be eliminated.

Further, the amount of ink droplets (landing amount) in the corner Q of the seal material forming area E is set to be smaller than the landing amount in the seal material forming area E other than the corner Q by reducing the number of landings per unit time. Alternatively, the amount of landing on the corner Q of the seal material forming area E is made substantially the same as the amount of landing on the seal material forming area E other than the corner Q by reducing the discharge amount of ink droplets per landing. It is preferable to control the total amount so that For example, the scanning position (μm) of the inkjet head and the number of impacts per unit time (time / se
The relationship with c) can be shown in the graph of FIG. The inkjet head starts ejecting ink droplets from outside the sealing material forming area E or above the protruding portion forming area W, and is usually 13000 times / sec to 15000 times / s.
ec is ejected, but the number of impacts is gradually reduced from 50 μm before the position corresponding to the corner Q of the seal material forming region E, and the number of impacts is minimized at the corner Q (6500 times / se).
c-7500 times / sec). Next, at a position corresponding to the seal material formation region E, 13000 times / sec to 1
The landing frequency is set to 5000 times / sec, and the landing frequency is gradually reduced from 50 μm before the position corresponding to the next corner Q to minimize the landing frequency at the corner Q. Further, the relationship between the scanning position (μm) of the inkjet head and the ejection amount of ink droplets per landing (pl / landing) is shown in FIG.
It can be shown by the graph of (b). Similar to FIG. 6A, normally, ink droplets are ejected at 6 pl / landing to 8 pl / landing, and 50 μm at the position of the corner Q of the seal material forming region E is ejected.
The landing amount is gradually reduced from the front side to the minimum (3 pl / landing to 4 pl / landing) in the corner Q. Next, at the position of the seal material forming region E, a steady discharge amount of 6 pl / landing to 8 pl / landing is set, the discharge amount is gradually reduced from 50 μm before the next corner position, and the discharge amount at the corner portion Q. Minimize.

The shape of the sealing material 108 is, for example, as shown in FIG.
As shown in (a), it is preferable to form the opening 110 for liquid crystal encapsulation so as to have a projecting end portion S that projects further outside than the projecting portion W outside the corner Q. By forming in this way, injection of liquid crystal and sealing of the opening 110 can be facilitated.

Further, as shown in FIG. 7B, the opening 110 of the sealing material 108 may be formed at an intermediate position in the scanning direction of the ink jet head. By forming in this way, the protrusion W formed outside the sealing material 108
The liquid crystal can be injected and the opening 110 can be sealed without being affected by the above.

As shown in FIG. 7C, the shape of the sealing material 108 is in the scanning direction of the ink jet head.
The land may be landed on the outer region T from the seal material forming region E (see FIG. 5).

Further, as shown in FIG. 7 (d), the sealing material 108 may not have the opening 110.
