Problems solved by technology

[0004] However, when the glass substrate is thinned by etching or the like before forming display device members on the surface of the glass substrate, the strength of the glass substrate decreases and the amount of warpage increases.
Therefore, a problem that cannot be handled by the existing production line arises
[0005] In addition, when the glass substrate is thinned by etching or the like after the member for the display device is formed on the surface of the glass substrate, in the process of forming the member for the display device on the surface of the glass substrate, the micro scratches formed on the surface of the glass substrate become Obvious problem, that is, the problem of pitting

Embodiment 1

[0262] Manufactured and used with the above by the following method figure 1 , figure 2 The glass laminate of Embodiment 1 described above is basically the same glass laminate. The only difference from Embodiment 1 is the size of the thin glass substrate and the supporting glass substrate. In the glass laminate of Embodiment 1, the main surface area of ​​the thin glass substrate 12 is smaller than that of the supporting glass substrate 18 , but in the glass laminate produced in Example 1, both glass substrates have the same size.

[0263] First, for a length of 720mm, a width of 600mm, a plate thickness of 0.4mm, and a linear expansion coefficient of 38×10 -7 The surface of the supporting glass substrate (manufactured by Asahi Glass Co., Ltd., AN100) at / °C was cleaned with pure water and UV.

[0264]Then, 100 parts by mass of silicone for solvent-free addition reaction release paper (manufactured by Shin-Etsu Silicone Co., Ltd., KNS-320A (viscosity: 0.40 Pa·s)) and a plat...

Embodiment 2

[0277] Use thermoplastic polyimide resin (manufactured by Mitsui Chemicals, AURUM PLC450C) (5% by mass thermal weight loss temperature = 570 ° C), melt it, and form the outer frame layer by extrusion dispensing method, except that it is the same as the embodiment 1 in the same manner to manufacture two glass laminates. And "glass laminated body B-1" which was not heat-processed, and "glass laminated body B-2" which heat-processed were obtained similarly to the case of Example 1. In addition, independently under high vacuum (1.0×10 -5 Pa) Although the temperature of the glass laminate B was raised from room temperature to 450° C., no gas was generated from the glass laminate B. In the obtained glass laminated body B-1 and glass laminated body B-2, the thin glass substrate and the silicone resin adhered without air bubbles, had no convex defects, and had good smoothness.

[0278] In addition, when the above-mentioned peeling test 1 was performed on each of the glass laminated ...

Embodiment 3

[0280] Example 3 is the same as Example 1, but differs in the type, size, thickness, etc. of the supporting glass substrate, resin layer, outer frame layer, and thin glass substrate.

[0281] As a supporting glass substrate, use a length of 720mm, a width of 600mm, a thickness of 0.6mm, and a linear expansion coefficient of 38×10 -7 / °C glass substrate (manufactured by Asahi Glass Co., Ltd., AN100).

[0282] In addition, as the resin for forming the resin layer, a linear polyorganosiloxane having vinyl groups at both ends (manufactured by Arakawa Chemical Industry Co., Ltd., trade name: 8500) and a methyl group having a hydrosilyl group in the molecule were used. Hydrogen polysiloxane (manufactured by Arakawa Chemical Industry Co., Ltd., trade name: 12031). And, it was mixed with a platinum-based catalyst (manufactured by Arakawa Chemical Industry Co., Ltd., trade name: CAT12070) to prepare a mixture, and was coated with a size of 700 mm in length and 580 mm in width by a scr...

Abstract

Disclosed is a glass laminate (10) comprising a thin glass substrate (12) having a first major surface and a second major surface, a supporting glass substrate (18) having a first major surface and a second major surface, and a resin layer (14) and an outer frame layer (16) arranged between the thin glass substrate (12) and the supporting glass substrate (18). The resin layer (14) is fixed to thefirst major surface of the supporting glass substrate (18) and is in close contact with the first major surface of the thin glass substrate (12), while having easy releasability from the first major surface of the thin glass substrate (12). The outer frame layer (16) surrounds the resin layer (14) on the first major surface of the supporting glass substrate (18) so that the outside air does not come into contact with the resin layer (14).

Description

technical field [0001] The present invention relates to a glass laminate including a glass substrate used in a liquid crystal display device, an organic EL display device, etc., a panel for a display device with a support including the glass laminate, and a display device formed using the panel with a support A panel, a display device including the panel for a display device, a glass laminate, and a method for manufacturing the panel for a display device. Background technique [0002] In the fields of liquid crystal display devices (LCD), organic EL display devices (OLED), and especially portable display devices such as mobile phones and mobile phones, weight reduction and thinning of display devices are important issues. [0003] In order to cope with this problem, it is desired to further reduce the plate thickness of the glass substrate used for the display device. As a method of reducing the thickness of the plate, there is generally a method of etching the glass substr...
