1277812

Field of the Invention The present invention relates to a liquid crystal display device and a method thereof which are capable of improving productivity. BACKGROUND OF THE INVENTION Since the prior art, for example, as shown in FIGS. 3 and 4, a liquid helium panel as a liquid crystal display device includes two glass substrates 21a, 21b each having a constant electrode-fixed interval & mutual phase = . The spacing is set to a few microseconds (5 to 7 microns). / The two glass substrates 21a and 21b are provided with a sealing material 22 for fixing and sealing the inner peripheral portions of the opposite faces, and the spacers 24 for uniformly ensuring the interval between the glass substrates 21a and 2b. use. Therefore, the liquid crystal panel is formed of two glass substrates 21a and 21b, a sealing material 22 and a spacer 24, and forms an internal space having a certain interval du. The above interval dn is borrowed by the spacer 24 to ensure uniformity along the respective glass substrates 21a, 21b. Such a liquid crystal panel is connected to the internal space and the outside during the manufacturing process, and the injection portion 28 is provided in the sealing material 22 as a path for injecting the liquid crystal material 25. The liquid crystal process of injecting one of the processes of the liquid crystal panel is as described below with reference to Fig. 35. First, the liquid crystal material 25 is injected into the internal space of the liquid crystal panel before the internal space of the liquid crystal panel, and evacuation is performed in the airtight container. In this state, the liquid crystal material 2 5 is in contact with the liquid crystal material 2 5 outside the liquid crystal panel, and the pressure in the airtight container is gradually restored to atmospheric pressure. Thus, the liquid crystal material 25 is filled in the internal space of the liquid crystal panel by the difference in gas pressure. Moreover, as shown in FIG. 4, the liquid crystal panel structure is generally used to seal the liquid crystal material 25 between two substrates, for example, the pixel electrode type displayed at the intersection of the electrodes.

1277812 V. Liquid crystal panel (simple matrix LCD) of the invention (2), and a liquid crystal panel of a TFT type (active array LCD) which is displayed on a thin film transistor of one substrate electrode intersection portion and each pixel electrode connected thereto . The above LCD is an abbreviation for Liquid Crystal D i s p 1 a y. However, in the liquid crystal panel of the prior art, the two glass substrates forming the liquid crystal panel have a small interval of a few micrometers between the 2 1 a and 2 1 b, and the viscosity coefficient of the liquid crystal material 25 is large. Therefore, the flow resistance is increased. It takes a lot of time to fill the liquid crystal material 25 in the inner space of the liquid crystal panel. In recent years, the development of liquid crystal panels has increased. In particular, as a large-sized liquid crystal panel used for a monitor, the liquid crystal material of the prior liquid crystal panel has a longer injection time, which causes a problem of a significant decrease in productivity. Further, even if the internal space 夂 spacing du of the liquid crystal panel is narrower, the injection time of the liquid crystal panel structure 'the liquid crystal material 25 is still long, and there is a problem that the productivity is remarkably lowered. A first object of the present invention is to provide a liquid crystal display device which can shorten the injection time of the liquid crystal material 25 to the internal space formed by each of the glass substrates 21a and 21b of the liquid crystal panel and the sealing material 22. In order to achieve the above first object, a liquid crystal display device according to the present invention is characterized in that: the substrate comprises: two substrates which are spaced apart and opposed to each other; the sealing material = 丄 sealed for the peripheral portion of the two substrates; and the liquid crystal material is enclosed by 2 γ = internal space formed by the material; the injection portion is formed in the sealing material = 曰曰 material is injected into the internal space; and the groove is at least one of the surface of the injection substrate substrate and the liquid crystal material.

Page 7 1277812 - V. DESCRIPTION OF THE INVENTION (3) According to the above configuration, since the contact surface of the two substrates with the liquid crystal material is small, the injection portion is provided, for example, according to the injection position and the opening shape. In the vicinity of the injection portion in the internal space, the internal space between the groove and the substrate of the ear is spaced apart from the gap between the two substrates, and the main groove is widened, that is, widened. Therefore, in the above structure, since the liquid crystal material injected into the internal space is rapidly grooved, the liquid crystal material enters the internal space other than the injection portion from the injection portion and the injection groove, so that the liquid crystal injected into the internal empty gate from the injection portion can be reduced as compared with the prior art. Flow resistance of the material.

As a result, in the above configuration, since the liquid crystal material is injected into the internal space more quickly than before, the injection time of the liquid crystal material can be shortened, and productivity can be improved.
