Description

剥離層形成用組成物Release layer forming composition
 本発明は、ガラス基板直上に設ける剥離層を形成するための組成物に関する。 The present invention relates to a composition for forming a release layer provided directly on a glass substrate.
 近年、電子デバイスには曲げるという機能付与や薄型化および軽量化といった性能が求められている。このことから、従来の重く脆弱で曲げることができないガラス基板に代わって、軽量なフレキシブルプラスチック基板を用いることが求められる。また、新世代ディスプレイでは、軽量なフレキシブルプラスチック基板を用いる、アクティブフルカラー(active full-color)TFTディスプレイパネルの開発が求められている。
 そこで、樹脂フィルムを基板とした電子デバイスの製造方法が各種検討され始めており、新世代ディスプレイでは、既存のTFT設備を転用可能なプロセスで製造検討が進められている。
In recent years, electronic devices have been required to have the functions of bending, thinning and lightening. For this reason, it is required to use a lightweight flexible plastic substrate in place of the conventional glass substrate that is fragile and cannot be bent. In the new generation display, development of an active full-color TFT display panel using a lightweight flexible plastic substrate is required.
Therefore, various methods for manufacturing electronic devices using a resin film as a substrate are being studied, and in the new generation display, manufacturing studies are being carried out in a process that can divert existing TFT equipment.
 特許文献1、2及び3は、ガラス基板上にアモルファスシリコン薄膜層を形成し、その薄膜層上にプラスチック基板を形成した後に、ガラス面側からレーザーを照射して、アモルファスシリコンの結晶化に伴い発生する水素ガスによりプラスチック基板をガラス基板から剥離する方法を開示する。
 また、特許文献4は、特許文献1~3開示の技術を用いて被剥離層(特許文献4において「被転写層」と記載される)をプラスチックフィルムに貼りつけて液晶表示装置を完成させる方法を開示する。
In Patent Documents 1, 2, and 3, an amorphous silicon thin film layer is formed on a glass substrate, a plastic substrate is formed on the thin film layer, and then a laser is irradiated from the glass surface side to accompany crystallization of amorphous silicon. A method of peeling a plastic substrate from a glass substrate with generated hydrogen gas is disclosed.
Patent Document 4 discloses a method for completing a liquid crystal display device by attaching a layer to be peeled (described as “transfer target layer” in Patent Document 4) to a plastic film using the techniques disclosed in Patent Documents 1 to 3. Is disclosed.
 しかし、特許文献1~4開示の方法、特に特許文献4開示の方法は、透光性の高い基板を使用することが必須であり、基板を通過させ、さらに非晶質シリコンに含まれる水素を放出させるのに十分なエネルギーを与えるため、比較的大きなレーザー光の照射が必要とされ、被剥離層に損傷を与えてしまうという問題がある。また、レーザー処理に長時間を要し、大きな面積を有する被剥離層を剥離するのは困難であるため、デバイス作製の生産性を挙げることは難しい、という問題もある。 However, in the methods disclosed in Patent Documents 1 to 4, particularly the method disclosed in Patent Document 4, it is essential to use a highly light-transmitting substrate, and hydrogen contained in amorphous silicon is allowed to pass through the substrate. In order to give energy sufficient to emit, there is a problem that irradiation with a relatively large laser beam is required and the layer to be peeled is damaged. In addition, since it takes a long time for laser treatment and it is difficult to peel off a layer to be peeled having a large area, there is a problem that it is difficult to increase the productivity of device fabrication.

 表2から次のことがわかる。実施例1~5の剥離層は、試験Iの結果が5Bであることから、基板から剥離層が剥がれることがない一方、試験IIの結果がAAであることから、剥離層から被剥離体層のみが剥離することがわかる。要するに、本発明の剥離層用組成物から形成された剥離層は、所望の剥離結果をもたらすことがわかる。
 一方、比較例1及び比較例3は、試験Iの結果がAAであるため、剥離層が基板から剥離することがわかる。要するに、比較例1及び比較例3は、所望の剥離結果を得ることができないことがわかる。また、比較例2は、試験I及び試験IIが共に5Bであることから、剥離層と基板との界面においても、剥離層と被剥離体層との界面においても剥離せず、所望の剥離結果を得ることができないことがわかる。
Table 2 shows the following. In the peeling layers of Examples 1 to 5, since the result of Test I is 5B, the peeling layer is not peeled off from the substrate, while the result of Test II is AA. It turns out that only peels. In short, it can be seen that the release layer formed from the composition for release layer of the present invention provides a desired release result.
On the other hand, Comparative Example 1 and Comparative Example 3 show that the release layer peels from the substrate because the result of Test I is AA. In short, it can be seen that Comparative Example 1 and Comparative Example 3 cannot obtain a desired peeling result. In Comparative Example 2, since both Test I and Test II are 5B, neither the interface between the release layer and the substrate nor the interface between the release layer and the layer to be peeled is peeled off. It can be seen that cannot be obtained.
