Definitions
- the present invention relates to an optical film with an adhesive used for forming an image display device having a transparent plate or a touch panel on the front surface of an image display panel. Furthermore, this invention relates to the manufacturing method of the image display apparatus using the said optical film with an adhesive.
- Liquid crystal display devices and organic EL display devices are widely used as various image display devices such as mobile phones, car navigation devices, personal computer monitors, and televisions.
- a polarizing plate is disposed on the viewing side surface of the image display cell because of its display principle.
- a circularly polarizing plate (polarizing plate and 1) is provided on the viewing side surface of the image display cell in order to prevent external light from being reflected by the metal electrode (cathode) and viewed as a mirror surface. / 4 wavelength plate laminate) may be disposed.
- a polarizing plate is disposed on the outermost surface of an image display panel (liquid crystal panel or organic EL panel).
- a front transparent plate also referred to as a “window layer” or the like
- a transparent resin plate or a glass plate is provided on the viewing side of the image display panel for the purpose of preventing damage to the image display panel due to an impact from the outer surface. May be provided.
- the touch panel is generally disposed on the viewing side of the image display panel (hereinafter, the front transparent plate and the touch panel may be collectively referred to as “front transparent member”).
- a gap of about 0.5 to 1.5 mm is provided between these layers in order to protect the panel surface.
- An air gap structure (hollow structure) is configured.
- the refractive index of air in the air gap structure portion is about 1
- the refractive index of the plastic material or glass material constituting the polarizing plate or front transparent member of the image display panel is about 1.5. Therefore, reflection and refraction at the interface increase.
- an “interlayer filling structure” in which the air gap structure portion is filled with a transparent optical resin having a refractive index close to that of glass, resin, or the like (for example, Patent Documents). 1 and 2).
- the optical resin is filled in the air gap, so that the difference in the refractive index at the interface is reduced, so that a decrease in visibility due to reflection and scattering is suppressed.
- the strength of the entire image display device is increased by filling the air gap with the optical resin, even if the front transparent plate or the like is broken, the forming material glass or the like is scattered. The effect of preventing this is also obtained.
- an adhesive as the optical resin constituting the interlayer filler, the image display panel and the front transparent member can be bonded and fixed.

第二粘着剤層22の厚さは、30μm以上が好ましく、40μm以上がより好ましく、50μm以上がさらに好ましい。第二粘着剤層の厚みが前記範囲より小さいと、光学フィルムと前面透明部材との貼り合せの際に、気泡が混入し易くなる傾向がある。
第二粘着剤層22は、25℃における貯蔵弾性率G’25℃が、1.0×104Pa~1.0×107Paであることが好ましい。第二粘着剤層は、G’25℃が、3.0×104Pa~7.0×106Paであることがより好ましく、5.0×104Pa~5.0×106Paであることがさらに好ましい。
第二粘着剤層22を構成する粘着剤の組成は特に限定されず、アクリル系ポリマー、シリコーン系ポリマー、ポリエステル、ポリウレタン、ポリアミド、ポリビニルエーテル、酢酸ビニル/塩化ビニルコポリマー、変性ポリオレフィン、エポキシ系、フッ素系、天然ゴム、合成ゴム等のゴム系等のポリマーをベースポリマーとするものを適宜に選択して用いることができる。特に、光学的透明性および接着性に優れ、かつ貯蔵弾性率を上記範囲に調整する観点から、アクリル系ポリマーをベースポリマーとするアクリル系粘着剤が好ましく用いられる。
光学フィルム10に第一粘着剤層21および第二粘着剤層22を形成する方法としては、例えば、前記粘着剤組成物を剥離処理したセパレータ等に塗布し、溶媒等を乾燥除去して、必要に応じて架橋処理を行って粘着剤層を形成した後に、光学フィルム10上に転写する方法;または光学フィルム10に前記粘着剤組成物を塗布し、溶媒等を乾燥除去して、粘着剤層を光学フィルム上に形成する方法、等が挙げられる。
第一粘着剤層21および第二粘着剤層22のそれぞれには、保護シート31,32が剥離可能に貼着される。保護シート31,32は、粘着剤付き光学フィルム55が実用に供され、画像表示セル60や前面透明部材70と貼り合せられるまでの間、粘着剤層21,22の露出面を保護する目的で用いられる。
粘着剤付き光学フィルムは、必要に応じて所望サイズにカットされた後、実用に供される。一般には、長尺状に形成された粘着剤付き光学フィルムが、画像表示装置のサイズ(画面サイズ)と合致する製品サイズにカットされる。カット方法としては、トムソン刃等を用いて打ち抜く方法や、丸刃や皿刃等のカッターを用いる方法や、レーザー光、水圧を利用する方法等が挙げられる。
本発明の両面粘着剤付き光学フィルムは、図3に模式的に示すように、偏光板を含む光学フィルム10の一方の面に液晶セルや有機ELセル等の画像表示セル60を備え、他方の面(視認側)にタッチパネルや前面透明板等の前面透明部材70を備える画像表示装置100の形成に好適に用いられる。当該画像表示装置において、画像表示セル60は、第一粘着剤層21を介して光学フィルム10と貼り合せられ、前面透明部材70は、第二粘着剤層22を介して光学フィルム10と貼り合せられる。
<偏光板>
ヨウ素が含浸された厚み25μmの延伸ポリビニルアルコールフィルムからなる偏光子の両面に透明保護フィルムが貼り合せられた偏光板(偏光度99.995%)を用いた。偏光子の一方の面(画像表示セル側)の透明保護フィルムは、厚さ40μmのトリアセチルセルロースフィルムからなる位相差フィルムであり、他方の面(視認側)の透明保護フィルムは、厚さ60μmのトリアセチルセルロースフィルムであった。

上記偏光板の一方の面にセル側粘着剤層として上記の粘着剤層Aを貼り合せた。その後、偏光板の他方の面に視認側粘着剤層として上記の粘着剤層B1を貼り合せた後、セパレータを剥離し、その上に粘着剤層B1を貼り合せて、粘着剤層B1が2層(合計厚み300μm)の粘着剤層とした。
上記の両面粘着剤付き光学フィルムを、48mm×98mmのサイズにトムソン刃で打ち抜いた。同一サイズに打ち抜かれた両面粘着剤付き光学フィルムを50枚積み重ね、その上下から万力状の治具にてフィルムを保持し、光学フィルムの端面から粘着剤層がはみ出るように加圧した。この状態で、光学フィルムの端面から0.5mm内側を、回転刃を用いて光学フィルムおよびセパレータと共に粘着剤層ごと切削した。その後、上記圧力を解放し、製品サイズにカットされた両面粘着剤付き偏光板を得た。
両面粘着剤付き偏光板の一方の面(粘着剤層A側)に平坦なガラス板(0.7mm×50mm×100mm)が貼り合せられ、他方の面(粘着剤層B側)には、黒色インク(厚み10μm)が周縁部に枠状に印刷されたガラス板(0.7mm×50mm×100mm、インク印刷幅:端部から10mm)が貼り合せられ、評価用疑似画像表示装置が作製された。
視認側の粘着剤層Bとして、表1に示す組成の粘着剤組成物(溶液)を調製した。粘着付与剤として、実施例2ではスチレンオリゴマー(ヤスハラケミカル(株)製「YSレジン SX-85」、軟化点85℃)が用いられ、実施例3では核水添テルペンフェノール(ヤスハラケミカル(株)製 「YSポリスターNH」、軟化点130℃)が用いられた。なお、実施例2,3の粘着剤は、光重合性のアクリル系モノマーとしてフェニルグリシジルエーテルアクリレート(第一工業製薬(株)製 「ニューフロンティア PGA」)、光ラジカル発生剤として1-ヒドロキシシクロヘキシルフェニルケトン(チバスペシャリティケミカルズ製 「イルガキュア184」)を含有する光硬化性粘着剤である。

上記ポリマー2を用いて、表1に示す組成の粘着剤組成物(溶液)が調製された。粘着剤層Bとして、表1に示す組成および厚みを有する粘着剤層が用いられたこと以外は実施例1と同様にして両面粘着剤付き偏光板が作製された。なお、実施例4においては、粘着剤溶液をセパレータ上に塗布し、乾燥した後、50℃で48時間加熱して、架橋処理を行った。
それぞれ、上記実施例2,3,5および6と同様の両面粘着剤付き光学フィルムを用いて、カッティングおよびガラス板との貼り合せを行った。オートクレーブ処理後に、視認側のガラス板を介して、高圧水銀ランプ(10mW/cm2)で紫外線を照射し、光硬化性粘着剤の硬化を行った(積算光量:3000mJ/cm2)。
上記実施例1において、表1に示すように、粘着剤B1に粘着付与剤が添加され、粘着剤層の厚みが変更された。それ以外は実施例1と同様にして、両面粘着剤付き偏光板が作製され、カッティングおよびガラス板との貼り合せが行われた。実施例11では、粘着付与剤として、スチレンオリゴマー(ヤスハラケミカル(株)製「YSレジン SX-100」、軟化点100℃)が用いられ、実施例12では、水素化ロジンエステル(荒川化学工業(株)製 「パインクリスタル KE-311」、軟化点95℃)が用いられた。
上記実施例1において、視認側の粘着剤層B1の厚みが20μm(1層のみ)に変更された。それ以外は実施例1と同様にして、両面粘着剤付きフィルムの作製、および評価用疑似画像表示装置の作製が行われた。
上記比較例1において、カッティングの際に、トムソン刃による打ち抜きのみが行われ、回転刃による切削が行われなかった。それ以外は比較例1と同様にして、両面粘着剤付きフィルムの作製、および評価用疑似画像表示装置の作製が行われた。
偏光板の一方の面に粘着剤層Aが貼り合せられ、他方の面に粘着剤を有していない片面粘着剤付きフィルムを作製した。この片面粘着剤付き光学フィルムをトムソン刃により打ち抜き、粘着剤層上のセパレータを剥離した後、平坦なガラス板の一面に、粘着剤層がガラス面に接するように載置して貼り合せた。
(液状接着剤の調製)
表1に示すように、粘着付与剤70重量部(核水添テルペンフェノール40重量部、およびアクリルオリゴマー30重量部)とアクリル系モノマー(フェニルグリシジルエーテルアクリレート)30重量部をフラスコ中100℃で2時間加熱撹拌溶解した後、50℃まで冷却した。冷却後の溶液に、光重合開始剤(1-ヒドロキシシクロヘキシルフェニルケトン)5重量部を加え、50℃で2時間加熱撹拌溶解した後冷却した。その後、真空(700Pa)で1時間脱気し、ベースポリマーを含まないUV硬化型液状接着剤組成物(溶液)を調整した。
上記比較例3と同様に、片面粘着剤付き光学フィルムと平坦なガラス板との貼り合せまでを行った。その後、ガラス板上に貼り合せられた偏光板上に、上記のUV硬化型液状接着剤溶液を適量塗布し、印刷されたガラス板の印刷面と液状接着剤が接するよう載置した。その後、両者を真空貼り合せ装置(温度25℃、圧力0.003MPa、圧力保持時間5秒)で貼り合せた後、視認側のガラス板を介して、高圧水銀ランプ(10mW/cm2)で紫外線を照射し、接着剤の硬化を行った(積算光量:6000mJ/cm2)。
<粘着剤付き光学フィルムの端面(側面)の評価>
疑似画像表示装置の側面を観察したところ、比較例3および比較例4では、層間充填のために付設された接着剤(粘着剤)が積層体の端面からはみ出していた。
粘着剤付き光学フィルムの側面を手で触れて、粘着感の有無を確認したところ、各実施例および比較例1では、粘着感が無かったが、比較例2では粘着感があった(比較例3,4は未評価)。
粘着剤付き光学フィルム50枚を積み重ねて梱包し、トラックの荷台に保持した状態で約10時間輸送した後開封した。各実施例および比較例1では糊欠けを生じたものはなかったが、比較例2では50枚中8枚の光学フィルムにおい、350μm以上の糊欠けが発生していた。(比較例3,4は未評価)。
各実施例および比較例の粘着剤層(光学フィルムとの貼り合せ前のもの)からセパレータを剥離し、複数の粘着剤層を積層して厚さ約1.5mmとしたものを測定用サンプルとした。Rheometric Scientific社製「Advanced Rheometric Expansion System(ARES)」を用いて、以下の条件により、動的粘弾性測定を行い、測定結果から、サンプルの25℃における貯蔵弾性率G’25℃および80℃における貯蔵弾性率G’80℃を読み取った。同様の測定方法により、実施例2a,3a,5aおよび6aの硬化後の粘着剤層についても貯蔵弾性率を測定した。
