Description of the Invention (/) Background of the Invention The present invention relates to a glass substrate and a glass composition for a liquid crystal panel. Ground is abbreviated as glass substrate and glass composition. Recently, there is a tendency to use a liquid crystal panel or a display in various fields. For example, LCD panels can also be used on desktop computers and digital video disc (DVD) players. In view of this fact, the required liquid crystal panel is light in weight, small in size, and capable of displaying very detailed images. So far, what is needed for the liquid crystal panel glass composition is that it has a high strain point, light weight, and high strength like a thin film transistor (TFT) to form a liquid crystal panel. Here, it should be noted that the traditional TFTs are classified into amorphous silicon TFT and polysilicon TFT. Among them, the amorphous TFT system can analyze a wide screen and can be made in a low temperature process. This amorphous TFT has a wider range of uses than a polysilicon TFT. However, such an amorphous TFT in the structure inevitably drives a current due to the characteristics of the material, and as a result, it will be difficult to make a good integrated body. On the other hand, polysilicon TFTs have the advantage that they can simplify the driving current in the structure and thus form high-density pixels. However, a disadvantage of polysilicon TFT systems is that high-temperature processes are required when manufacturing polysilicon. Although recent research on polysilicon TFTs has pointed out that polysilicon TFTs can be made by low-temperature processes, they document an indispensable method between 600 ° C and 65CTC.

Description of the invention (&); Under these circumstances, the liquid crystal panel glass is usually formed of quartz glass. The quartz glass The system is highly stable, even when it shrinks or deforms. This type of quartz glass is suitable for use in a liquid crystal panel, but it is quite expensive. Another option is to include glass called non-alkali glass which does not contain alkaline components, which has been used as a liquid crystal panel glass. However, there is no plan, and it has been revealed that non-alkaline glass with high strain point can be manufactured by polysilicon TFT process. In addition, a more suitable liquid crystal panel is lightweight because the liquid crystal panel is often used in external devices, such as in-vehicle devices and desktop computers. Furthermore, a liquid crystal panel having a low specific gravity and a low flexibility is required so as to be easily handled in a glass manufacturing process and a test process. This low flexibility results in a high Young's modulus. Generally, such a glass filled with the required properties as described above can be predicted to have poor solubility and a very high melting temperature. This will make it difficult to refine and standardize. In addition, there is no disclosure, it has been pointed out that the glass composition and the glass substrate have a strain point of not less than 680 ° C, and a specific modulus of not less than 31 Gpa, which is a pair of Young's modulus Specific gravity ratio 値. SUMMARY OF THE INVENTION The object of the present invention is to provide a glass substrate or composition of a liquid crystal panel suitable for a polysilicon TFT substrate and having a high strain point of not less than 680 ° C.

The present invention also has another object, which is to provide a glass substrate or composition of a liquid crystal panel of this type having good solubility and good refining and standardization. Another object of the present invention is to provide a glass substrate or composition of a liquid crystal panel of this type which has excellent anti-vitrification effect and refining or degassing properties, and has substantially no cracks. Another object of the present invention is to provide a glass material base or composition of a liquid crystal panel having such a form with a high specific modulus of not less than 31 GPa. According to the present invention, the liquid crystal panel has a high strain point of not less than 680 ° C, a specific gravity of not more than 2.45, and a Young's modulus of not less than 76 Gpa. A more suitable liquid crystal panel has a high strain point of not less than 690 ° C, a specific gravity of not more than 2. 42 and a Young's modulus of not less than 77 Gpa.

Strain point, specific gravity not higher than 2.45 (more preferably 2.42), and Young's modulus not less than 76 Gpa (more preferably 77 Gpa).

Description of the invention (4 ratio Given: By using the above-mentioned Young's modulus and specific modulus, the glass substrate or composition system according to the present invention has a specific modulus of not less than 3 1 G pa. In order to calculate the Young's modulus (E), the prepared calcined glass sample having a density (p) and a size of 20 X 20 X 100 mm is introduced into a chamber maintained at a high temperature. After that, its longitudinal velocity (VL) is measured and its値 is an ultrasonic wave of 6 megahertz. In this case, its Young's modulus is calculated by the following formula: E = (4G2- 3GVl2 P) / (G-VL2 p) where G is the shear force Modulus or rigid modulus. In addition, when the specific gravity of the glass substrate is reduced in the liquid crystal display, it may reduce the curl or deformation modulus of the glass substrate. This is because the curl (W) is caused by Given by the formula: W = (L4gp (l-v 2 p)) / (6.4Et2y〇) where L and t represent the length and thickness of the glass sample, respectively, and y is the Bouyson ratio, and. The curl w depends on the p / E. This means that the curl (W) decreases as the specific gravity p decreases. Glass with strain point, specific gravity, and Young's modulus as described above, including 67 -72 mol% SiO2, 6.10 mol% B203, 9-15 mol 1203, 3-13 mol% Mg〇, 0-6 mol% CaO, 0-0.3 mol% SrO, 0-0.2 mole% BaO and 0-0.5 mole% As 203.

Description of the invention (7) Considering the above, it can be summarized as: applicable The glass substrate or glass composition of the liquid crystal panel may include: 65-75 mole% SiO2, 6-11 mole% β2 03, 8-15 mole% Al203, 3-15 mole MgO , 0-8 mole% CaO, 0-1 mole% SrO, 0-1 mole% BaO, 0-1 mole% As 203, 0.1 mole% Sb203, and 0-1 mole% Sn02 . Furthermore, when (AU〇3 / B2〇3) falls within the range of Morr ratios between 1.1 and 2.2, the first total amount of (Al 203 + Mg0 + Ca0) is located at 20 Mor % And 25 mole%. Similarly, when the second ratio of the first total amount (Al203 + MgO + CaO) to the third total amount (Si02 + B203) is (Al203 + Mg0 + Ca0) / (Si02 + B203) When the system is not less than 0.25, the (Si02 + B2 03 + A 1 203 + Mg0 + Ca0) second total amount may be not less than 98 mol%, and a more ideal glass substrate or glass composition system may include (In mole%): 68-72% SiO2, 7-9% B203, 9-13% AU〇3, 5-13.5% MgO, 〇-3.4% CaO, 0-0.4% SrO, 0- 0.01% BaO, 0-0.5% As203, 0-0.5% Sb203, and 0-0,5% Sn02. Regarding the facts described above, the reasons for the restrictions are explained below. In order to achieve a strain point of not less than 670 ° C, the first ratio of Al2O3 to B2O3 includes (Al2O3 / B2O3) maintained at not less than 8 mol% in the range of 1.1. A 1 203 and B203 of not more than 11 mol%. From this viewpoint of strain, the alkali metal oxide system is more preferably excluded from glass. Glass with a specific gravity not greater than 2. 4 5 can be maintained by keeping the first total amount (Al 203 + Mg0 + Ca0) within a range of not more than 25 mole%, and the second total amount (Si02 + B203 + Al 203 + Mg0 + Ca0), which is kept at not less than 97 -9- This paper size applies to the Chinese National Standard (CNS) A4 specification (210 X 297 mm) ---- · --- ^ ---- pack- ------- Order --------- ^ __ WT (Please read the notes on the back before filling out this page) 544445 A7 __ B7 V.

It is assumed that the Al2O3 series does not exceed 15 mol%, and when the Si02 and B2O3 series are equal to or greater than 65 mol% and 6 mol%, respectively, the anti-vitreous effect can be maintained. In this event, the first ratio (ai2O3 / b2O3) needs to remain equal to or less than 2.2, and the amounts of CaO, SrO, and BaO added are up to 8 mole%, 1 Mole% and 1 Mole%. More specifically, when the viscosity of glass is increased by more than 75 mole% Si02f, the strain point of Si02 less than 65 mole% will be improperly reduced. When greater than 11 mole% B203 results in a decrease in fluoric acid resistance, then less than 6 mole% of B203 will reduce its solubility. AU03 outside the range of 5 mol% and 15 mol% will reduce the strain point and increase the devitrification effect, respectively. When greater than 15 mole% MgO causes devitrification in the glass, then less than 3 mole% MgO will increase the viscosity. Similarly, greater than 15 mol% CaO causes devitrification in the glass.
