preparation example Construction

[0131]

[0132] In order to prepare the resin composition of the present invention, the above-mentioned components (A), optionally (B) and / or (C), and the above-mentioned components (D), (E), ( F), (G), (H), other components. For example, a required amount of each raw material is put into a SUS preparation box equipped with stirring blades, and stirred until uniform at room temperature. Moreover, you may further filter the composition obtained using a mesh, a membrane filter, etc. as needed.

[0133]The resin composition thus obtained has a viscosity of preferably 0.5 to 3.0 Pa·s, more preferably 0.7 to 2.0 Pa·s, particularly preferably 1.0 to 1.8 Pa·s. By having a viscosity within this range, the permeability to the inside of the glass panel is improved, and breakage of the etched glass panel can be prevented. In addition, although the viscosity is also set according to the size of the gap (gap) between the glass panels, a viscosity of 0.5 Pa·s or more can maintain the co...

Abstract

This production method for a glass substrate that is thinned by etching is characterized by comprising: a step in which a composition comprising a resin that is obtained by reacting a polyol (a1) having a main component (A) that is selected from among polybutadiene polyol, hydrogenated polybutadiene polyol, polyisoprene polyol, and hydrogenated polyisoprene polyol with a crosslinking agent (a2) is applied to the outer peripheral surface of a glass panel to form an outer peripheral seal; and a step in which etching is performed to make the resulting glass panel thinner.

Description

technical field [0001] The present invention relates to a method of manufacturing a thinned glass substrate including the steps of using a resin composition and forming a seal on the outer periphery of the glass substrate. Background technique [0002] In recent years, along with the demand for thinner display panels of liquid crystal televisions, mobile phones, etc., thinner display devices such as liquid crystal display panels are also required. For the thinning of display devices, a method of bonding thin glass to produce a display device, and a method of physically or chemically thinning a glass part after manufacturing a display device have been studied. What is obtained by laminating glass in this way is also called a glass panel. Among them, in the method of bonding thin glass to manufacture a display device, the strength is insufficient due to the use of thin glass, and thus the glass panel is likely to be damaged during the manufacturing process. Then, the method ...
