Description

1257950 IX. Description of the invention: [Technical field to which the invention pertains] Δ The present invention relates to an aqueous liquid detergent composition for cleaning a liquid crystal panel. [Prior Art] The liquid crystal panel originally has the advantage of low power consumption. In addition, in recent years, there has been considerable progress in technologies such as high contrast, so it has been used to display images. For example, in a wide range of fields such as computer terminal displays and small panels of TV glory products, the application of the typical liquid crystal panel process is to make a predetermined distance below the two glass substrates and bond the two pieces with an adhesive. The base--hollow portion' then encapsulates the liquid crystal material into this::, inside. Inside the two glass substrates, an electrode for displaying characters c is formed, which is composed of a transparent conductive thin crucible. When the control signal is added, the display of the text and the image can be controlled: ϊ: [In the process of the 曰 panel, the next part of the two substrates is a small width of several meters, and the two gaps of the real estate cannot be avoided. Therefore, when the liquid crystal material is injected into the hollow portion, it is interposed between the substrate and the substrate. The liquid crystal material dissolved in the void by the action of ^^ ,, the liquid crystal material dissolved in the void is located at the ancient two-two gap just in the application of the electrical signal to the transparent electrode, and the respective insulated electrodes of the (four) degree configuration Where the terminal is located, so 10959pifl.doc 6 1257950 The problem that causes insulation degradation must be removed and removed. Therefore, the liquid crystal intruding into the voids, however, is extremely narrow because the substrate spacing at the voids is 10 μηη or less, so the cleaning agent used must have a high cleaning ability in order to completely remove the invading liquid crystal material. Among the detergents which are conventionally used, the effect is preferably a chlorine-containing organic solvent such as fluorine alkane (1?1011), trichloroethane, ethylene ethylene, tetraethylene, and dichloromethane. 1 However, since the regulation of gas-containing organic solvents is an important part of the world's environmental protection program, it is greatly limited in use. /, ^ For this reason, in the development of alternative cleaning agents, high demand, 丄, /ν » Ν / 〆Α , , 一些 一些 一些 , , , , , , , , , , , , , , , , , , , , 新型 新型 新型 新型 新型 新型 新型 新型 新型 新型It is a solvent of a hydrocarbon type, or a mixed composition of a hydrazine hydride-soluble hydrazine glycol ether, as described in Japanese Patent No. -25495. However, the application of the monthly lotion is high, so it is quite difficult to handle. , #,ϋ With the high-density technology of liquid crystal panels in recent years, the spacing of the work gaps is even narrower, and the production is improved. Therefore, it is necessary to have a cleaning solution in a short time: : Southern washing ability. In addition, in order to improve the growth and yield of the liquid crystal panel, not only the liquid crystal material that penetrates the void portion but also the surface of the cleaning electrode terminal must be cleaned in a large amount in the process of the liquid crystal panel, and the raw material must be clarified. j is a large piece of glass substrate 'and the powder that is cut in the lance (hereinafter referred to as eullet), which will be attached to the electricity 10959pifl.doc 7 丄 257950 Subsequent encapsulation process, so it must be attached = ΐ:::: surface foreign matter is usually only intermolecular force agent, and liquid crystal material as a combination of cleaning agent must be killed, such as sputum special glass powder The use of 5-27169" flute h Shen Qiao early public bulletin said that the second of its ==::: Γ Γ 晶 晶 晶 晶 晶 晶 晶 晶 晶 晶 晶 晶 晶 晶 晶 晶 晶 晶 晶 晶 晶 晶 晶 晶 晶 晶 晶 晶 晶 晶 晶 晶 晶 晶 晶 晶 晶 晶The effect, so =: glass to:: crystal material as a bonding agent and closely attached (four) the main 1 ° on the description, so far there is no kind of burden on the environment and: material 2 / low, and can be washed at the same time Foreign matter on the surface of the liquid crystal material invading the void portion and the surface of the liquid electrode panel In addition, in recent years, in response to display quality requirements of personal computers, mobile phones, and pdas, the demand for color liquid crystal panels has rapidly increased. Therefore, in addition to conventional super-twisted arrays for passive panels. In addition to the type (STN) liquid crystal material, a liquid crystal material for a thin film transistor (TFT) used for an active panel has also been developed. The STN liquid crystal material currently used is an aromatic compound having a substituent represented by a cyano group. The compound, and the TFT liquid crystal material is an aromatic compound having a substituent represented by a fluorine atom. 10959pifl.doc 8 1257950 Since the molecular structure and physical properties of the STN liquid crystal material and the TFT liquid crystal material are different, it is necessary to use different cleaning agents. It can be cleaned. In other words, the STN liquid crystal material can be effectively washed by the above-mentioned hydrocarbon solvent or a mixture of a hydrocarbon solvent and a glycol ether, but the TFT liquid crystal material cannot be used, but must be different. Cleaning agent to clean. However, in order to improve the productivity of liquid crystal panels, it is suitable for molecular structure and physical properties. A variety of liquid crystal materials have various needs for cleaning compositions. However, so far, there is no good cleaning power which can effectively clean a variety of liquid crystal materials, and the burden and toxicity to the ring & In view of the above, one of the objects of the present invention is to provide a liquid crystal panel cleaning composition for liquid crystal panels, which can effectively remove liquid crystal material that invades the voids of the liquid crystal panel. And a foreign matter adhering to the surface of the electrode terminal of the liquid crystal panel such as glass frit, and having a small burden on the environment and toxicity. The flammability is also low. Another object of the present invention is to provide a liquid liquid detergent composition for a double liquid crystal panel. It can effectively remove various liquid crystal materials which are caused by molecular structure differences*. In order to achieve the above object, the inventors have found out that the cleaning agent composition containing the following components can effectively remove the liquid crystal material which is in the void of the liquid crystal panel, and at the same time attaches a foreign matter on the surface of the substrate to the glass powder or the like. There is also a high level of soaking ability'. These ingredients include specific nonionic interface/activity with branching, 10959pifl.doc 9 1257950 agent, specific glycol ether compounds, and hydrocarbons. At the same time, the detergent composition containing hydrocarbons, specific glycol ethers, anionic surfactants, and yttrium (DMSO) is not cleaned by the physical properties of STN liquid crystal materials and TFT liquid crystal materials.嘁k, so it can effectively remove the two.
