Description

黏著板片、顯示體以及該等物件之製造方法 Adhesive plate, display body and manufacturing method of the objects

本發明係關於，用於貼合顯示體構成構件的黏著板片；及貼合顯示體構成構件而成的顯示體；以及該等物件之製造方法。 The present invention relates to an adhesive sheet used for bonding the constituent members of a display body; and a display body formed by bonding the constituent members of the display body; and a method of manufacturing these objects.

近幾年的行動電話、智慧型手機、平板電腦等的各種行動電子機器，具備使用液晶元件、發光二極體(LED元件)、有機電致發光(有機EL)元件等的顯示體模組的顯示體(顯示器)。 In recent years, various mobile electronic devices such as mobile phones, smart phones, and tablet computers have display modules using liquid crystal elements, light-emitting diodes (LED elements), and organic electroluminescence (organic EL) elements. Display body (display).

在該顯示器，通常，在顯示體模組的表面側設置保護面板。在保護面板與顯示體模組之間，設有即使因外力使保護面板變形時，不會使變形的保護面板撞到顯示體模組的空隙。 In this display, usually, a protective panel is provided on the surface side of the display module. Between the protective panel and the display module, there is a gap that prevents the deformed protective panel from hitting the display module even when the protective panel is deformed due to external forces.

但是，存在如上所述的空隙，即空氣層，則起因於保護面板與空氣層的折射率差，及空氣層與顯示體模組的折射率差的光反射損失大，而有降低顯示器的畫質的問題。因此，有藉由將保護面板與顯示模組之間的空隙以黏著劑層填埋，以提升顯示器的畫質的提案。 However, the existence of the above-mentioned voids, that is, the air layer, is caused by the refractive index difference between the protective panel and the air layer, and the refractive index difference between the air layer and the display module has a large light reflection loss. Qualitative issue. Therefore, there are proposals to improve the image quality of the display by filling the gap between the protective panel and the display module with an adhesive layer.

例如，在專利文獻1，揭示使用紫外線架橋性黏著板片，填埋保護面板與顯示體模組之間的空隙，該紫外線架橋 性黏著板片，係包含(甲基)丙烯酸共聚物而成，該(甲基)丙烯酸共聚物，包含：具有紫外線架橋性部位的(甲基)丙烯酸酯的單體。 For example, in Patent Document 1, it is disclosed that an ultraviolet-ray bridging adhesive sheet is used to fill the gap between the protective panel and the display module. The ultraviolet-ray bridging The adhesive sheet is composed of a (meth)acrylic copolymer, and the (meth)acrylic copolymer contains a monomer of (meth)acrylate having an ultraviolet-ray bridging site.

然而，在顯示體，在填埋保護面板與顯示體模組之間的空隙以外，亦使用黏著劑層。例如，在專利文獻2揭示，藉由包含含有多官能環氧基的有機矽化合物的黏著劑組合物所形成的黏著劑層，貼合液晶胞與偏光板。 However, in the display body, in addition to filling the gap between the protective panel and the display body module, an adhesive layer is also used. For example, Patent Document 2 discloses that a liquid crystal cell and a polarizing plate are bonded to an adhesive layer formed by an adhesive composition containing an organosilicon compound containing a polyfunctional epoxy group.

[專利文獻2]日本特開2014-074097號公報 [Patent Document 2] JP 2014-074097 A

在包含如上所述的黏著劑層的顯示體，黏著劑層有時在耐久條件下會發生問題。例如，施以高溫高濕條件時，由保護面板的樹脂板發生釋氣(outgas)，而有時發生氣泡、浮起、剝落的等的起泡。 In the display body including the adhesive layer as described above, the adhesive layer sometimes causes problems under durable conditions. For example, when high-temperature and high-humidity conditions are applied, outgas occurs from the resin plate that protects the panel, and bubbles, floating, peeling, and the like may sometimes occur.

特別是，車用的顯示體，由要求耐久性的觀點，使用厚度相對較厚的樹脂製保護面板，由減低成本的觀點，使用在貼合黏著板片側的面、省略硬塗層處理的樹脂保護面板。使用如此的保護面板時，由於釋氣的產生量會變得相對較多，在如專利文獻1及2所揭示的先前的黏著板片，有時無法充分抑制發生起泡。 In particular, for automotive displays, from the viewpoint of durability, a relatively thick resin protective panel is used, and from the viewpoint of cost reduction, a resin that omits the hard coat treatment is used on the side where the adhesive sheet is attached. Protect the panel. When such a protective panel is used, since the amount of outgassing is relatively large, in the conventional adhesive sheets as disclosed in Patent Documents 1 and 2, the occurrence of blistering may not be sufficiently suppressed in some cases.

本發明係有鑑於上述實際情況而完成者，以提供即使貼合於釋氣的產生量相對較多的顯示體構成構件時，耐起泡性優良的黏著板片、耐起泡性優良的顯示體、以及該等物件之製造方法為目標。 The present invention was completed in view of the above-mentioned actual situation to provide an adhesive sheet with excellent blistering resistance and a display with excellent blistering resistance even when it is bonded to a display component that generates a relatively large amount of outgassing.

關於本實施形態的黏著板片，係具備用於將一的顯示體構成構件，與其他的顯示體構成構件貼合的黏著劑層的黏著板片。關於顯示體及顯示體構成構件，將於後述。 The adhesive sheet of the present embodiment is an adhesive sheet provided with an adhesive layer for bonding one display constituent member to the other display constituent members. The display body and the structural members of the display body will be described later.

如圖1所示，作為一例的本實施形態的黏著板片1，係由2片剝離板片12a、12b，以接於該等2片剝離板片12a、12b的剝離面，以該2片的剝離板片12a、12b所夾持的黏著劑層11所構成。再者，在本說明書的剝離板片的剝離面，係指在剝離板片具有剝離性的面，包含施以剝離處理的面及即使沒有施以剝離處理亦顯示剝離性的面的任一面。 As shown in Fig. 1, as an example, the adhesive sheet 1 of the present embodiment consists of two peeling sheets 12a, 12b to be connected to the peeling surfaces of the two peeling sheets 12a, 12b. The adhesive layer 11 sandwiched by the release sheet 12a, 12b is formed. In addition, the peeling surface of a peeling sheet in this specification means the surface which has peelability in a peeling sheet, and includes either the surface to which the peeling process is applied and the surface which shows peelability even if it does not apply the peeling process.

1.黏著劑層 1. Adhesive layer

上述黏著劑層11，係具有由(甲基)丙烯酸酯共聚物(A)與熱架橋劑(B)構成的架橋結構的同時，由含有活性能量線硬化性成分(C)、含烷氧基矽基聚合物(D)、矽烷偶合劑(E)的活性能量線硬化性的黏著劑所組成。換言之，上述黏著劑層11，係由將含有(甲基)丙烯酸酯共聚物(A)、熱架橋劑(B)、活性能量線硬化性成分(C)、含烷氧基矽基聚合物(D)、矽烷偶合劑(E)的黏著劑組合物(以下有時稱為「黏著性組合物P」。)，熱架橋形成的活性能量線硬化性的黏著劑所組成。再者，在本說明書，(甲基)丙烯酸係指丙烯酸及甲基丙烯酸的雙方。其他的類似用語亦相同。 The adhesive layer 11 has a bridging structure composed of a (meth)acrylate copolymer (A) and a thermal bridging agent (B), and is composed of a curable component (C) containing active energy rays and an alkoxy group containing Silicon-based polymer (D) and silane coupling agent (E) are composed of active energy ray-curable adhesive. In other words, the adhesive layer 11 is composed of a (meth)acrylate copolymer (A), a thermal bridging agent (B), an active energy ray curable component (C), and an alkoxysilyl-containing polymer ( D) Adhesive composition of silane coupling agent (E) (hereinafter sometimes referred to as "adhesive composition P"), composed of active energy ray curable adhesive formed by thermal bridging. In addition, in this specification, (meth)acrylic acid means both acrylic acid and methacrylic acid. Other similar terms are also the same.

如上所述，在黏著板片1的黏著劑層11，係將黏著性組合物P熱架橋而成的黏著劑所組成，該黏著劑，具有由 (甲基)丙烯酸酯共聚物(A)與熱架橋劑(B)所構成的架橋結構(三維網眼結構)。另一方面，活性能量線硬化性成分(C)，尚未硬化，以調配在黏著性組合物P的原樣狀態存在於黏著劑中。活性能量線硬化性成分(C)，係在使用黏著板片1時(貼合於被著體之後)，對黏著劑層11照射活性能量線時聚合、硬化。 As described above, the adhesive layer 11 of the adhesive sheet 1 is composed of an adhesive formed by thermally bridging the adhesive composition P. The adhesive has A bridging structure (three-dimensional mesh structure) composed of (meth)acrylate copolymer (A) and thermal bridging agent (B). On the other hand, the active energy ray curable component (C) is not yet cured, and is present in the adhesive as it is formulated in the adhesive composition P. The active energy ray curable component (C) is polymerized and hardened when the adhesive layer 11 is irradiated with active energy rays when the adhesive sheet 1 is used (after being attached to the body).

因此，在關於本實施形態的黏著板片1，藉由黏著板片1的黏著劑層11，將一的顯示體構成構件與其他的顯示體構成構件貼合之後，經由一的顯示體構成構件或其他的顯示體構成構件，對黏著劑層11照射活性能量線，可使黏著劑層11硬化。如此地，在關於本實施形態的黏著板片1，由於藉由熱架橋在黏著劑層11中形成的架橋結構，藉由活性能量線的照射而進一步硬化，故所得黏著劑層11可成為具有相對較高的凝聚力的結果，能夠達成優良的耐起泡性。 Therefore, in the adhesive sheet 1 of the present embodiment, the one display body constituent member is bonded to the other display body constituent members through the adhesive layer 11 of the adhesive sheet 1, and then the one display body constituent member is pasted Or other display components, irradiating the adhesive layer 11 with active energy rays can harden the adhesive layer 11. In this way, in the adhesive sheet 1 of this embodiment, since the bridging structure formed in the adhesive layer 11 by thermal bridging is further hardened by the irradiation of active energy rays, the resulting adhesive layer 11 can become As a result of relatively high cohesion, excellent foam resistance can be achieved.

再者，在關於本實施形態的黏著板片1，黏著劑層11含有含烷氧基矽基聚合物(D)及矽烷偶合劑(E)。該等成分，可推測如前述，可增大黏著劑層11或以照射活性能量線的該硬化物的表面的密度及強度。藉此，黏著板片1，即使是貼合在釋氣的產生量相對較多的顯示體構成構件時，亦可達成優良的耐起泡性。 Furthermore, in the adhesive sheet 1 of this embodiment, the adhesive layer 11 contains an alkoxysilyl group-containing polymer (D) and a silane coupling agent (E). These components can be presumed to increase the density and strength of the adhesive layer 11 or the surface of the hardened product irradiated with active energy rays as described above. Thereby, the adhesive sheet 1 can achieve excellent blistering resistance even when it is bonded to a display component with a relatively large amount of outgassing.

[顯示體] [Display body]

如圖2所示，關於本實施形態的顯示體2，其構成具備：第1顯示體構成構件21(一的顯示體構成構件)；第2顯示體構 成構件22(其他的顯示體構成構件)，位於該等之間，將第1顯示體構成構件21及第2顯示體構成構件22互相貼合的硬化後黏著劑層11'。再者，在圖2，在第1顯示體構成構件21，硬化後黏著劑層11'側的面設有因印刷層3的段差，惟該印刷層3亦可省略。 As shown in FIG. 2, regarding the display body 2 of this embodiment, the structure includes: a first display body constituent member 21 (one display body constituent member); a second display body constituent member 22 (other display body constituent members) , Located in between, the first display body constituent member 21 and the second display body constituent member 22 are bonded to each other after curing adhesive layer 11 ′ . Furthermore, in FIG. 2, in the first display body constituent member 21, the surface on the side of the adhesive layer 11' after curing is provided with a step due to the printed layer 3, but the printed layer 3 may be omitted.

在上述顯示體2的硬化後黏著劑層11'，係將前述黏著板片1的黏著劑層11，藉由照射活性能量線而硬化。該硬化後黏著劑層11'，具有由(甲基)丙烯酸酯共聚物(A)與熱架橋劑(B)構成的架橋結構的同時，由含有活性能量線硬化性成分(C)的硬化物(聚合物)、含烷氧基矽基聚合物(D)、矽烷偶合劑(E)的黏著劑所組成。聚合的活性能量線硬化性成分(C)，可推測與(甲基)丙烯酸酯共聚物(A)及熱架橋劑(B)所構成的三維網眼結構纏繞。 After curing the adhesive layer 11 ′ of the display body 2, the adhesive layer 11 of the adhesive sheet 1 is cured by irradiating active energy rays. The cured adhesive layer 11 ′ has a bridge structure composed of (meth)acrylate copolymer (A) and thermal bridging agent (B), and is composed of a cured product containing active energy ray curable component (C) (Polymer), alkoxy silyl polymer (D), silane coupling agent (E) adhesive composition. The polymerized active energy ray curable component (C) can be presumably entangled with the three-dimensional network structure composed of the (meth)acrylate copolymer (A) and the thermal bridging agent (B).

再者，可推測在硬化後黏著劑層11'接於第1顯示體構成構件21及第2顯示體構成構件22的面附近，含烷氧基矽基聚合物(D)與上述三維架橋結構纏繞，藉此增加在該面的膜密度。此外，可推測矽烷偶合劑(E)，可使含烷氧基矽基聚合物(D)相互的架橋順利進行，而在該面的膜強度亦可進一步增強。 Furthermore, it can be inferred that after curing, the adhesive layer 11 ′ is connected to the vicinity of the surface of the first display body constituent member 21 and the second display body constituent member 22, and the alkoxysilyl polymer (D) and the above-mentioned three-dimensional bridge structure Winding, thereby increasing the density of the film on that side. In addition, it can be presumed that the silane coupling agent (E) can smoothly bridge the alkoxysilyl group-containing polymer (D) with each other, and the film strength on the surface can be further enhanced.

再者，含烷氧基矽基聚合物(D)及矽烷偶合劑(E)的一部分，在硬化後黏著劑層11'中，亦可用原樣的狀態存在。此外，亦可藉由在含烷氧基矽基聚合物(D)的矽基與矽烷偶合劑(E)之間的水解縮合，形成新的化學鍵結，亦可進一步經由該鍵結使含烷氧基矽基聚合物(D)相互架橋。或者，亦可不經 由矽烷偶合劑(E)，而藉由含烷氧基矽基聚合物(D)相互直接水解縮合形成架橋結構。或者，亦可藉由含烷氧基矽基聚合物(D)或矽烷偶合劑(E)所具有的矽基，與(甲基)丙烯酸酯共聚物(A)所具有的反應性基之間水解縮合反應，形成新的化學鍵結。或者，亦可藉由含烷氧基矽基聚合物(D)或矽烷偶合劑(E)所具有的矽基，與被著體表面的反應性基之間的水解縮合反應形成化學鍵結。 Furthermore, a part of the alkoxysilyl-containing polymer (D) and the silane coupling agent (E) may exist in the adhesive layer 11' after hardening. In addition, it is also possible to form a new chemical bond through the hydrolytic condensation between the silyl group of the alkoxysilyl-containing polymer (D) and the silane coupling agent (E), and the alkane-containing compound can be further formed through the bond The oxysilyl polymer (D) bridges each other. Alternatively, it is also possible to form a bridging structure by directly hydrolyzing and condensing the alkoxysilyl group-containing polymers (D) without using the silane coupling agent (E). Alternatively, it can also be used between the silyl group contained in the alkoxysilyl group-containing polymer (D) or the silane coupling agent (E) and the reactive group contained in the (meth)acrylate copolymer (A) Hydrolysis and condensation reactions form new chemical bonds. Alternatively, it is also possible to form a chemical bond by the hydrolytic condensation reaction between the silyl group contained in the alkoxysilyl group-containing polymer (D) or the silane coupling agent (E) and the reactive group on the surface of the substrate.

In addition, the display body 2 may be a member constituting a part of these.

第1顯示體構成構件21的材料，雖可為玻璃板、樹脂板，惟以樹脂板特別佳。此外，第1顯示體構成構件21，亦可為包含玻璃板、樹脂板等的層積體。此時，該層積體，至少包含樹脂板作為接於硬化後黏著劑層11'的層為佳。如此地，即使是樹脂板對硬化後黏著劑層11'直接層積時，由於硬化後黏著劑層11'是將關於本實施形態的黏著板片1的黏著劑層11硬化形成，故能夠達成優良的耐起泡性。 Although the material of the first display body constituent member 21 may be a glass plate or a resin plate, a resin plate is particularly preferred. In addition, the first display body constituent member 21 may be a laminate including a glass plate, a resin plate, and the like. At this time, the laminate preferably includes at least a resin plate as the layer connected to the cured adhesive layer 11 ' . In this way, even when the resin plate is directly laminated on the cured adhesive layer 11' , the cured adhesive layer 11' is formed by curing the adhesive layer 11 of the adhesive sheet 1 of the present embodiment, so it can be achieved Excellent foam resistance.

第1顯示體構成構件21，可為厚度0.5mm以上，5mm以下的樹脂板。如此地，使用具有相對較厚的樹脂板作為第1顯示體構成構件21，即使是估計從第1顯示體構成構件21的釋氣的會發生相對較多，由於硬化後黏著劑層11'是將關於本實施形態的黏著板片1的黏著劑層11硬化形成，故可達成優良的耐起泡性。再者，上述樹脂板的厚度，以0.7mm以上 特別佳，進一步以1.5mm以上為佳。另一方面，該厚度，以3.5mm以下特別佳，進一步以2.5mm以下為佳。 The first display body constituent member 21 may be a resin plate having a thickness of 0.5 mm or more and 5 mm or less.

此外，第1顯示體構成構件21，亦可係至少在接於硬化後黏著劑層11'的面(黏著板片1被貼合側的面)不具有硬塗層的樹脂板。一般，在表面沒有設置硬塗層的樹脂板，該表面會產生相對較多的釋氣，但即使是使用如此的樹脂板，由於硬化後黏著劑層11'是將關於本實施形態的黏著板片1的黏著劑層11硬化而成，故可達成優良的耐起泡性。 In addition, the first display body constituent member 21 may be a resin plate that does not have a hard coat layer at least on the surface (the surface on the side where the adhesive sheet 1 is bonded) that is connected to the hardened adhesive layer 11'. Generally, a resin board with no hard coat layer on the surface will generate relatively much outgassing on the surface. However, even if such a resin board is used, the adhesive layer 11 ′ after curing is related to the adhesive board of this embodiment. Since the adhesive layer 11 of the sheet 1 is hardened, it can achieve excellent blistering resistance.

第1顯示體構成構件21，特別是作為保護面板的第1顯示體構成構件21，可含有紫外線吸收劑。此時，顯示體2可成為耐光性優良，即使是使製造後的顯示體2由第1顯示體構成構件21側沐浴到紫外線，可抑制硬化後黏著劑層11'及其下層的第2顯示體構成構件22的惡化。 The first display component 21, particularly the first display component 21 as a protective panel, may contain an ultraviolet absorber. At this time, the display body 2 can be excellent in light resistance, even if the manufactured display body 2 is bathed in ultraviolet rays from the side of the first display body constituent member 21, the second display of the adhesive layer 11' and its lower layer after curing can be suppressed The body constituent member 22 is deteriorated.

In addition, the transparent conductive film and the metal layer can also be patterned. Furthermore, it is preferable that the above-mentioned hard coat layer can be provided as a functional layer. In this case, the hard coat layer is preferably provided on the surface opposite to the surface of the cured adhesive layer 11 ′ connected to the first display body constituent member 21 .

構成印刷層3的材料，並無特別限定，可使用印刷用的習知的材料。印刷層3的厚度，即段差的高度的下限值，以3μm以上為佳，以5μm以上更佳，以7μm以上特別佳，以10μm以上最佳。藉由使下限值在上述以上，可充分確保由視認者側看不到電性配線等的隱蔽性。此外，上限值，以50μm以下為佳，以35μm以下更佳，以25μm以下特別佳，進一步以20μm以下為佳。藉由使上限值在上述以下，可防止硬化後黏著劑層11'對該印刷層3的段差追隨性的惡化。 The material constituting the printing layer 3 is not particularly limited, and conventional materials for printing can be used. The thickness of the printed layer 3, that is, the lower limit of the height of the step, is preferably 3 μm or more, more preferably 5 μm or more, particularly preferably 7 μm or more, and most preferably 10 μm or more.

As an example, one part of the plate 1 is adhered The square peeling sheet 12a is peeled off, and the exposed adhesive layer 11 of the adhesive sheet 1 is bonded to one surface of the first display body constituent member 21. Next, the peeling sheet 12b on the other side is peeled from the adhesive layer 11 of the adhesive sheet 1, and the exposed adhesive layer 11 of the adhesive sheet 1 and the second display constituent member 22 are bonded together to obtain a laminate. In addition, as another example, the order of bonding the first display body constituent member 21 and the second display body constituent member 22 may be exchanged.

之後，對上述層積體中的黏著劑層11照射活性能量線。藉此，黏著劑層11中的活性能量線硬化性成分(C)聚合，使黏著劑層11硬化成為硬化後黏著劑層11'。對黏著劑層11的活性能量線的照射，通常，係隔著第1顯示體構成構件21或第2顯示體構成構件22的任意一方進行，較佳的是隔著作為保護面板的第1顯示體構成構件21進行。 After that, the adhesive layer 11 in the laminate is irradiated with active energy rays.
