Glass composition of glass substrate of liquid crystal display

Abstract

The invention discloses glass composition of a glass substrate of a liquid crystal display. The glass substrate comprises the following chemical components in percentage by weight: 55 to 61 percent of silicon oxide, 13 to 17 percent of aluminum oxide, 8 to 12 percent of boron oxide, 1 to 7.0 percent of strontium oxide, 0.1 to 8.0 percent barium oxide, 0 to 8 percent of calcium oxide, 1.5 to 6 percent of zinc oxide and 0 to 2 percent of arsenic oxide, wherein the silicon oxide and the aluminum oxide account for over 70 percent of the glass substrate; and the calcium oxide, the strontium oxide, the barium oxide and the zinc oxide account for 8 to 20 percent of the glass substrate. The glass composition has the advantages of ensuring more accurate proportioning of each component by long-term experiment and manufacturing high-quality glass substrate, along with high economy and high practicability.

Description

technical field [0001] The invention relates to an alkaline earth borosilicate glass formula, which can be widely used in glass substrates of TFT-LCD liquid crystal displays. Background technique [0002] The imaging principle of liquid crystal display, first of all, matter has three states: solid state, liquid state and gas state. In fact, the so-called three states are only roughly distinguished, and the solid state of some substances can be subdivided into states of different properties. Similarly, liquids can also have different "states". Liquid crystals in which the molecular arrangement is directional are called liquid crystals, or "liquid crystals" for short. [0003] For components made of liquid crystals, the liquid crystals are usually wrapped in two pieces of glass. A layer of alignment agent is coated on the surface of the glass. Its type and treatment method can control the alignment of liquid crystals when there is no external electric field. [0004] The ima...
