Description

ディスプレイ用保護フィルムProtective film for display
　本発明は、ディスプレイの表示領域を保護するためのディスプレイ用保護フィルムに関するものである。 The present invention relates to a display protective film for protecting a display area of a display.
　携帯電話機、ゲーム機又はタブレット端末などの各種機器のディスプレイには、少なくとも表示領域を保護するために保護フィルムが貼り合せられる場合がある。この種の保護フィルムの中には、単にディスプレイの表示領域を保護するためだけでなく、光反射防止機能などの他の機能を有するものもある。 Protective films may be attached to the displays of various devices such as mobile phones, game machines, and tablet terminals to protect at least the display area. Some protective films of this type not only protect the display area of the display but also have other functions such as a light reflection preventing function.
　保護フィルムは、ディスプレイの表示領域を覆って保護する基材フィルム層に、粘着層を介して他のフィルム層を積層することにより構成されている。具体的には、基材フィルム層の一方の面に粘着層を介して剥離フィルム層が積層されており、当該剥離フィルム層を粘着層から剥離した後、粘着層をディスプレイの表示領域に貼り合せることができる。基材フィルム層の他方の面には、必要に応じて、各種機能に対応するフィルム層が積層される。 The protective film is configured by laminating another film layer through an adhesive layer on a base film layer that covers and protects the display area of the display. Specifically, a release film layer is laminated on one surface of the base film layer via an adhesive layer, and after peeling the release film layer from the adhesive layer, the adhesive layer is bonded to the display area of the display. be able to. A film layer corresponding to various functions is laminated on the other surface of the base film layer as necessary.
　一般的な保護フィルムでは、１枚の剥離フィルム層が粘着層全体を覆っており、当該剥離フィルム層を剥離して粘着層全体を露出させた後、ディスプレイの表示領域に貼り合せられる。このとき、ユーザは、表示領域に対して保護フィルムを位置合わせしながら貼り合せることとなり、通常、１回で正確な位置に貼り合せることは困難である。 In a general protective film, one release film layer covers the entire adhesive layer, and after peeling the release film layer to expose the entire adhesive layer, it is bonded to the display area of the display. At this time, the user attaches the protective film while aligning the protective film with respect to the display area, and it is usually difficult to attach the protective film at an accurate position once.
　そのため、多くのユーザは、表示領域に対して保護フィルムを途中まで貼り合せた後、表示領域から一旦剥離させ、再度位置合わせをしながら貼り合せるといった作業を繰り返すこととなる。この場合、粘着層の粘着力が低下したり、粘着層と表示領域との間に埃や気泡が入り込んだりするなどの問題が生じるおそれがある。そこで、近年では、保護フィルムを１回で正確な位置に貼り合せることが容易になるような構成が提案されている（例えば、下記特許文献１及び２参照）。 For this reason, many users repeat the work of pasting the protective film to the display area halfway, then peeling it off from the display area, and pasting it while aligning again. In this case, there is a possibility that problems such as a decrease in the adhesive strength of the adhesive layer, and dust or bubbles entering between the adhesive layer and the display area may occur. Therefore, in recent years, a configuration has been proposed in which it is easy to attach the protective film to an accurate position at one time (for example, see Patent Documents 1 and 2 below).
　特許文献１には、剥離フィルム層に切り込みが形成されることにより、剥離フィルム層が２分割された構成が開示されている。具体的には、剥離フィルム層が仮止め用剥離層及び本止め用剥離層に分割されており、仮止め用剥離層を剥離して粘着層の一部を表示領域に貼り合せた後、本止め用剥離層を剥離して粘着層の残りの部分を表示領域に貼り合せることにより、表示領域全体に保護フィルムを貼り合せることができる。 Patent Document 1 discloses a configuration in which a release film layer is divided into two parts by forming cuts in the release film layer. Specifically, the release film layer is divided into a temporary fastening release layer and a permanent fastening release layer. After peeling the temporary fastening release layer and pasting a part of the adhesive layer to the display area, A protective film can be bonded to the entire display area by peeling off the release layer for bonding and bonding the remaining part of the adhesive layer to the display area.
　特許文献２には、治具を用いて保護フィルムを貼り合せるための構成が開示されている。具体的には、治具を用いてディスプレイ（ケース）を位置決めした上で、保護フィルムを保持する保持フィルムに設けられた貫通孔内に、治具に形成されている突出部を挿入することにより、保持フィルムが位置合わせされる。その後、保持フィルムを押圧することにより、保護フィルムを表示領域に貼り合せることができる。 Patent Document 2 discloses a configuration for bonding a protective film using a jig. Specifically, by positioning the display (case) using a jig and inserting a protrusion formed on the jig into a through-hole provided in the holding film that holds the protective film The holding film is aligned. Thereafter, the protective film can be bonded to the display region by pressing the holding film.

　しかしながら、上記特許文献１のように剥離フィルム層を分割する構成では、剥離フィルム層に切り込みを形成する際に粘着層を傷付けてしまう場合がある。そこで、剥離フィルム層を粘着層から一旦剥離し、切込みを形成した後、粘着層に再度貼り合せることも考えられる。しかし、この場合には、保護フィルムの製造工程が複雑になるとともに、剥離フィルム層と粘着層との間に埃や気泡が入り込むなどの問題が生じるおそれがある。 However, in the configuration in which the release film layer is divided as in Patent Document 1, the adhesive layer may be damaged when a cut is formed in the release film layer. Therefore, it is also conceivable that the release film layer is once peeled off from the adhesive layer to form a cut and then pasted on the adhesive layer again. However, in this case, the manufacturing process of the protective film becomes complicated, and problems such as dust and air bubbles entering between the release film layer and the adhesive layer may occur.
　また、上記特許文献２のように治具を用いてディスプレイを位置決めするような構成では、わざわざ治具を準備する必要があるため、作業が大掛かりになるとともに、コストが高くなるという問題がある。 Further, in the configuration in which the display is positioned using a jig as in the above-mentioned Patent Document 2, it is necessary to prepare the jig for the purpose, so that there is a problem that the work becomes large and the cost becomes high.
　本発明は、上記実情に鑑みてなされたものであり、粘着層を傷付けることがないディスプレイ用保護フィルムを提供することを目的とする。また、本発明は、簡単な構成で正確な位置に容易に貼り合せることができるディスプレイ用保護フィルムを提供することを目的とする。 The present invention has been made in view of the above circumstances, and an object thereof is to provide a protective film for a display that does not damage the adhesive layer. Another object of the present invention is to provide a protective film for a display that can be easily bonded to an accurate position with a simple structure.
　本発明に係るディスプレイ用保護フィルムは、ディスプレイの表示領域を保護するためのディスプレイ用保護フィルムであって、基材フィルム層と、粘着層と、剥離フィルム層と、凸部とを備える。前記基材フィルム層は、前記表示領域を覆う。前記粘着層は、前記基材フィルム層の一方の面に形成されている。前記剥離フィルム層は、前記粘着層上に設けられ、前記粘着層に対して剥離可能である。前記凸部は、前記剥離フィルム層上の一部に固定され、その縁部に沿って前記剥離フィルム層を切り裂きながら剥離させる。 The display protective film according to the present invention is a display protective film for protecting the display area of the display, and includes a base film layer, an adhesive layer, a release film layer, and a convex portion. The base film layer covers the display area. The adhesive layer is formed on one surface of the base film layer. The release film layer is provided on the adhesive layer and can be peeled from the adhesive layer. The said convex part is fixed to a part on the said peeling film layer, and is peeled off while tearing the said peeling film layer along the edge.
　このような構成によれば、剥離フィルム層上に固定された凸部の縁部に沿って、剥離フィルム層を切り裂きながら剥離させることにより、粘着層の一部を露出させることができる。したがって、剥離フィルム層に切込みを形成する必要がないため、粘着層を傷付けることがない。 According to such a configuration, a part of the adhesive layer can be exposed by peeling off the release film layer along the edge of the convex portion fixed on the release film layer. Therefore, since it is not necessary to form a cut in the release film layer, the adhesive layer is not damaged.
　また、露出させた粘着層の一部を表示領域に貼り合せた後、残りの剥離フィルム層を剥離させることにより、粘着層の残りの部分を露出させることができる。したがって、保護フィルムの位置合わせの途中で粘着層全体が表示領域に貼り付いてしまうことがないため、簡単な構成で保護フィルムを正確な位置に容易に貼り合せることができる。 Also, after a part of the exposed adhesive layer is bonded to the display area, the remaining part of the adhesive layer can be exposed by peeling off the remaining release film layer. Therefore, since the entire adhesive layer is not attached to the display area during the alignment of the protective film, the protective film can be easily attached to an accurate position with a simple configuration.
　前記凸部の縁部は、前記剥離フィルム層の一端縁から他端縁まで、一直線上に延びていることが好ましい。 It is preferable that the edge of the convex part extends in a straight line from one end edge to the other end edge of the release film layer.
　このような構成によれば、剥離フィルム層の一端縁又は他端縁から、凸部の縁部に沿って容易に切込みを入れることができる。また、凸部の縁部が一直線上に延びているため、切込みを入れた剥離フィルム層を真っ直ぐ容易に切り裂くことができる。これにより、剥離フィルム層を切り裂きながら剥離させる作業を円滑に行うことができるため、作業性が向上する。 According to such a configuration, it is possible to easily make a cut along the edge of the convex portion from one edge or the other edge of the release film layer. Moreover, since the edge part of the convex part has extended on the straight line, the peeling film layer which made the cut can be cut straight easily easily. Thereby, since the operation | work which peels while peeling a peeling film layer can be performed smoothly, workability | operativity improves.
　また、本発明に係るディスプレイ用保護フィルムは、ディスプレイの表示領域を保護するためのディスプレイ用保護フィルムであって、基材フィルム層と、粘着層と、剥離フィルム層と、凸部とを備える。前記基材フィルム層は、前記表示領域を覆う。前記粘着層は、前記基材フィルム層の一方の面に形成されている。前記剥離フィルム層は、前記粘着層上に設けられ、前記粘着層に対して剥離可能である。前記凸部は、前記剥離フィルム層上に形成され、前記ディスプレイに係止されることにより位置決めされる。 The protective film for display according to the present invention is a protective film for display for protecting the display area of the display, and includes a base film layer, an adhesive layer, a release film layer, and a convex portion. The base film layer covers the display area. The adhesive layer is formed on one surface of the base film layer. The release film layer is provided on the adhesive layer and can be peeled from the adhesive layer. The convex portion is formed on the release film layer and is positioned by being locked to the display.
　このような構成によれば、剥離フィルム層上に形成された凸部をディスプレイに係止させて位置決めした状態で、凸部とは異なる領域で剥離フィルム層を剥離させることにより露出した粘着層の一部を表示領域に貼り合せることができる。その後、凸部を含む領域で残りの剥離フィルム層を剥離させることにより、粘着層の残りの部分を露出させ、表示領域に貼り合せることができる。これにより、剥離フィルム層上に形成された凸部をディスプレイに係止させるだけの簡単な構成で、保護フィルムを正確な位置に容易に貼り合せることができる。 According to such a configuration, the adhesive layer exposed by peeling the release film layer in a region different from the convex portion in a state where the convex portion formed on the release film layer is locked and positioned on the display. Part of it can be pasted into the display area. Thereafter, the remaining release film layer is peeled off in the region including the convex portion, so that the remaining portion of the adhesive layer can be exposed and bonded to the display region. Thereby, a protective film can be easily bonded to an accurate position with a simple configuration in which the convex portions formed on the release film layer are simply locked to the display.
　前記凸部は、前記ディスプレイの外縁に沿って係止されることにより位置決めされてもよい。 The convex portion may be positioned by being locked along the outer edge of the display.
　このような構成によれば、剥離フィルム層上に形成された凸部を、ディスプレイの外縁に沿って容易に係止させることができる。すなわち、凸部を係止させるための部分をディスプレイ側に別途設けることなく、ディスプレイの外縁を利用して凸部を係止させることができるため、より簡単な構成で保護フィルムを容易に貼り合せることができる。 According to such a configuration, the convex portion formed on the release film layer can be easily locked along the outer edge of the display. In other words, the projection can be locked using the outer edge of the display without providing a portion for locking the projection on the display side, so that the protective film can be easily bonded with a simpler configuration. be able to.
　前記凸部は、前記ディスプレイの表面に形成されている凹部に係止されることにより位置決めされてもよい。 The convex portion may be positioned by being locked to a concave portion formed on the surface of the display.
　このような構成によれば、剥離フィルム層上に形成された凸部を、ディスプレイの表面に形成されている凹部に容易に係止させることができる。この場合、スピーカ、マイク又はヘッドホンなどのためにディスプレイの表面に形成されている凹部を利用すれば、凸部を係止させるための部分をディスプレイ側に別途設ける必要がないため、より簡単な構成で保護フィルムを容易に貼り合せることができる。 According to such a configuration, the convex portion formed on the release film layer can be easily locked to the concave portion formed on the surface of the display. In this case, if a concave portion formed on the surface of the display is used for a speaker, a microphone, a headphone, or the like, it is not necessary to separately provide a portion for locking the convex portion on the display side. The protective film can be easily attached.
　本発明によれば、剥離フィルム層に切込みを形成する必要がないため、粘着層を傷付けることがない。また、保護フィルムの位置合わせの途中で粘着層全体が表示領域に貼り付いてしまうことがないため、簡単な構成で保護フィルムを正確な位置に容易に貼り合せることができる。 According to the present invention, since it is not necessary to form a cut in the release film layer, the adhesive layer is not damaged. In addition, since the entire adhesive layer does not adhere to the display area during the alignment of the protective film, the protective film can be easily attached to an accurate position with a simple configuration.
　本発明によれば、剥離フィルム層上に形成された凸部をディスプレイに係止させるだけの簡単な構成で、保護フィルムを正確な位置に容易に貼り合せることができる。 According to the present invention, the protective film can be easily bonded to an accurate position with a simple configuration in which the convex portion formed on the release film layer is simply locked to the display.

　以下では、本発明に係る保護フィルムの実施形態について詳細に説明する。なお、以下の実施形態において図示された保護フィルムの各層は、説明を分かりやすくするために、実際の厚みよりも大きい厚みで示されている。 Hereinafter, embodiments of the protective film according to the present invention will be described in detail. In addition, each layer of the protective film illustrated in the following embodiments is shown with a thickness larger than the actual thickness for easy understanding of the description.
　図１は、本発明の一実施形態に係る保護フィルム１０１の構成例を示した平面図である。また、図２は、図１における保護フィルム１０１のＡ－Ａ断面図であり、保護フィルム１０１の一部のみを示している。本実施形態に係る保護フィルム１０１は、携帯電話機、ゲーム機又はタブレット端末などの各種機器のディスプレイに貼り合せられ、当該ディスプレイの少なくとも表示領域を保護するためのディスプレイ用保護フィルムである。 FIG. 1 is a plan view showing a configuration example of a protective film 101 according to an embodiment of the present invention. 2 is a cross-sectional view taken along the line AA of the protective film 101 in FIG. 1, and shows only a part of the protective film 101. FIG. The protective film 101 according to the present embodiment is a display protective film that is attached to a display of various devices such as a mobile phone, a game machine, or a tablet terminal, and protects at least a display area of the display.
　保護フィルム１０１は、基材フィルム層１１１と剥離フィルム層１１２とが、粘着層１１３を介して積層されることにより構成されている。すなわち、基材フィルム層１１１の一方の面に粘着層１１３が形成され、粘着層１１３上に剥離フィルム層１１２が設けられている。基材フィルム層１１１の他方の面には、例えば光反射防止機能などの各種機能に応じた任意のフィルム層が積層されていてもよい。また、基材フィルム層１１１自体が、このような各種機能を有していてもよい。 The protective film 101 is configured by laminating a base film layer 111 and a release film layer 112 via an adhesive layer 113. That is, the adhesive layer 113 is formed on one surface of the base film layer 111, and the release film layer 112 is provided on the adhesive layer 113. On the other surface of the base film layer 111, for example, an arbitrary film layer corresponding to various functions such as a light reflection preventing function may be laminated. Moreover, the base film layer 111 itself may have such various functions.
　基材フィルム層１１１は、ディスプレイの表示領域を覆うことができる形状を有している。より具体的には、基材フィルム層１１１は、ディスプレイの表示領域と同一、又は、それよりも大きい形状を有している。この例では、基材フィルム層１１１が長方形状に形成されているが、ディスプレイの表示領域の形状に応じて、正方形状などの他の矩形状に形成されていてもよいし、矩形状に限らず円形や楕円形などの他の各種形状に形成されていてもよい。 The base film layer 111 has a shape that can cover the display area of the display. More specifically, the base film layer 111 has a shape that is the same as or larger than the display area of the display. In this example, the base film layer 111 is formed in a rectangular shape, but may be formed in another rectangular shape such as a square shape or the like, depending on the shape of the display area of the display. Instead, it may be formed in various other shapes such as a circle or an ellipse.
　粘着層１１３は、基材フィルム層１１１の一方の面の全体に形成されている。剥離フィルム層１１２は、基材フィルム層１１１よりも大きい形状を有しており、基材フィルム層１１１の周縁よりも外側に張り出した状態で積層されている。剥離フィルム層１１２は、例えば透明フィルムにより形成されており、図１の状態では、透明な剥離フィルム層１１２を通して裏側の基材フィルム層１１１が視認可能となっている。ただし、剥離フィルム層１１２は、基材フィルム層１１１と同一の形状であってもよく、透明でなくてもよい。 The adhesive layer 113 is formed on the entire one surface of the base film layer 111. The release film layer 112 has a shape larger than that of the base film layer 111 and is laminated in a state of protruding outward from the periphery of the base film layer 111. The release film layer 112 is formed of, for example, a transparent film. In the state shown in FIG. 1, the base film layer 111 on the back side is visible through the transparent release film layer 112. However, the release film layer 112 may have the same shape as the base film layer 111 or may not be transparent.
　剥離フィルム層１１２は、粘着層１１３に対して剥離可能となっている。したがって、剥離フィルム層１１２を剥離させて粘着層１１３を露出させ、当該粘着層１１３をディスプレイの表示領域に貼り合せることにより、表示領域を基材フィルム層１１１で覆って保護することができる。 The release film layer 112 can be peeled from the adhesive layer 113. Therefore, by peeling the release film layer 112 to expose the adhesive layer 113 and bonding the adhesive layer 113 to the display area of the display, the display area can be covered and protected by the base film layer 111.
　本実施形態では、剥離フィルム層１１２上の一部に凸部１１４が固定されている。当該凸部１１４は、例えば所定の幅を有する帯状に形成されており、基材フィルム層１１１の短辺に対して平行に延びている。この例では、凸部１１４の縁部１１４ａが、剥離フィルム層１１２の一端縁１１２ａから他端縁１１２ｂまで、一直線上に延びている。これにより、剥離フィルム層１１２は、その縁部１１４ａに沿って切り裂きながら剥離させることができるようになっている。 In this embodiment, the convex part 114 is fixed to a part on the peeling film layer 112. The protrusion 114 is formed in a band shape having a predetermined width, for example, and extends in parallel to the short side of the base film layer 111. In this example, the edge part 114a of the convex part 114 is extended on the straight line from the one end edge 112a of the peeling film layer 112 to the other end edge 112b. Thereby, the peeling film layer 112 can be made to peel while tearing along the edge 114a.
　剥離フィルム層１１２は、容易に切り裂くことができるような材料で形成されていることが好ましく、例えばポリプロピレンを原料とする二軸延伸フィルムにより形成することができる。剥離フィルム層１１２の厚みは、例えば１０～１００μｍ程度であることが好ましい。なお、基材フィルム層１１１及び粘着層１１３は、保護フィルムにおいて一般的に使用されている公知の材料により形成することができる。 The release film layer 112 is preferably formed of a material that can be easily cut, for example, a biaxially stretched film made of polypropylene as a raw material. The thickness of the release film layer 112 is preferably about 10 to 100 μm, for example. In addition, the base film layer 111 and the adhesion layer 113 can be formed with the well-known material generally used in the protective film.
　図３は、剥離フィルム層１１２を切り裂きながら剥離させる際の態様について説明するための平面図である。剥離フィルム層１１２を剥離させる際には、剥離フィルム層１１２の一端縁１１２ａにおける角部１１２ｃを摘まみ、凸部１１４の縁部１１４ａが延びる方向Ｄに沿って力を加えながら剥離させる。 FIG. 3 is a plan view for explaining an aspect when the release film layer 112 is peeled while being cut. When peeling the release film layer 112, the corner 112c of the one end edge 112a of the release film layer 112 is picked and peeled while applying a force along the direction D in which the edge 114a of the convex part 114 extends.
　これにより、図３に示すように、凸部１１４の縁部１１４ａに沿って剥離フィルム層１１２の一端縁１１２ａが切り裂かれる。そして、縁部１１４ａが延びる方向Ｄに沿ってそのまま力を加えることにより、縁部１１４ａに沿って剥離フィルム層１１２を一端縁１１２ａから他端縁１１２ｂまで切り裂きながら剥離させることができる。その結果、剥離フィルム層１１２の一部１１２ｄが除去され、この部分に対向する粘着層１１３が露出する。 Thereby, as shown in FIG. 3, the one end edge 112a of the peeling film layer 112 is torn along the edge part 114a of the convex part 114. Then, by applying a force as it is along the direction D in which the edge portion 114a extends, the release film layer 112 can be peeled along the edge portion 114a while being cut from the one end edge 112a to the other end edge 112b. As a result, a part 112d of the release film layer 112 is removed, and the adhesive layer 113 facing this part is exposed.
　このとき剥離される剥離フィルム層１１２の一部１１２ｄは、剥離フィルム層１１２の全体の面積に対して、半分以下の面積に対応する部分であることが好ましく、１／３～１／４の面積に対応する部分であればより好ましい。なお、剥離フィルム層１１２は、一端縁１１２ａからではなく、他端縁１１２ｂから切り裂かれてもよい。 The part 112d of the release film layer 112 to be peeled at this time is preferably a part corresponding to an area less than half of the entire area of the release film layer 112, and an area of 1/3 to 1/4. It is more preferable if it is a part corresponding to. Note that the release film layer 112 may be cut from the other end edge 112b instead of from the one end edge 112a.
　図４Ａ～図４Ｃは、図１の保護フィルム１０１をディスプレイ１の表示領域２に貼り合せる際の態様について説明するための概略断面図である。図３において説明したような態様で剥離フィルム層１１２の一部１１２ｄが剥離された後、保護フィルム１０１は、ディスプレイ１の表示領域２に対して位置合わせされる。 4A to 4C are schematic cross-sectional views for explaining a mode when the protective film 101 of FIG. 1 is bonded to the display region 2 of the display 1. After the part 112 d of the release film layer 112 is peeled in the manner described in FIG. 3, the protective film 101 is aligned with the display area 2 of the display 1.
　このとき、図４Ａに示すように、露出した粘着層１１３がディスプレイ１の表示領域２に対向するようにして、粘着層１１３を表示領域２から離した状態で保護フィルム１０１を移動させる。そして、基材フィルム層１１１の各辺が表示領域２の各辺に対して平行になり、かつ、基材フィルム層１１１が表示領域２全体を覆うように位置合わせした上で、図４Ｂに示すように、露出している粘着層１１３を表示領域２に貼り合せる。ただし、凸部１１４の表面を表示領域２に摺接させながら、保護フィルム１０１を水平方向に移動させて位置合わせを行うことも可能である。 At this time, as shown in FIG. 4A, the protective film 101 is moved in a state where the adhesive layer 113 is separated from the display region 2 so that the exposed adhesive layer 113 faces the display region 2 of the display 1. And after aligning so that each side of the base film layer 111 is parallel to each side of the display region 2 and the base film layer 111 covers the entire display region 2, it is shown in FIG. 4B. Thus, the exposed adhesive layer 113 is bonded to the display area 2. However, it is also possible to perform alignment by moving the protective film 101 in the horizontal direction while bringing the surface of the convex portion 114 into sliding contact with the display area 2.
　その後、剥離フィルム層１１２の残りの部分を凸部１１４側から剥離させ、図４Ｃに示すように、剥離フィルム層１１２を反転させて引き抜きながら、粘着層１１３の残りの部分を表示領域２に貼り合せる。このようにして、粘着層１１３全体を表示領域２に貼り合せることができる。 Thereafter, the remaining portion of the release film layer 112 is peeled off from the convex portion 114 side, and the remaining portion of the adhesive layer 113 is pasted on the display area 2 while being reversed and pulled out as shown in FIG. 4C. Match. In this way, the entire adhesive layer 113 can be bonded to the display area 2.
　以上のように、本実施形態では、剥離フィルム層１１２上に固定された凸部１１４の縁部１１４ａに沿って、剥離フィルム層１１２を切り裂きながら剥離させることにより、粘着層１１３の一部を露出させることができる。したがって、剥離フィルム層１１２に切込みを形成する必要がないため、粘着層１１３を傷付けることがない。 As described above, in this embodiment, a part of the adhesive layer 113 is exposed by peeling off the release film layer 112 along the edge 114a of the protrusion 114 fixed on the release film layer 112. Can be made. Accordingly, since it is not necessary to form a cut in the release film layer 112, the adhesive layer 113 is not damaged.
　また、露出させた粘着層１１３の一部を表示領域２に貼り合せた後、残りの剥離フィルム層１１２を剥離させることにより、粘着層１１３の残りの部分を露出させることができる。したがって、保護フィルム１０１の位置合わせの途中で粘着層１１３全体が表示領域２に貼り付いてしまうことがないため、簡単な構成で保護フィルム１０１を正確な位置に容易に貼り合せることができる。 Further, after a part of the exposed adhesive layer 113 is bonded to the display region 2, the remaining part of the adhesive layer 113 can be exposed by peeling off the remaining release film layer 112. Therefore, since the entire adhesive layer 113 is not attached to the display area 2 during the alignment of the protective film 101, the protective film 101 can be easily attached to an accurate position with a simple configuration.
　特に、本実施形態では、凸部１１４の縁部１１４ａが剥離フィルム層１１２の一端縁１１２ａから他端縁１１２ｂまで延びているため、剥離フィルム層１１２の一端縁１１２ａ又は他端縁１１２ｂから、凸部１１４の縁部１１４ａに沿って容易に切込みを入れることができる。また、凸部１１４の縁部１１４ａが一直線上に延びているため、切込みを入れた剥離フィルム層１１２を真っ直ぐ容易に切り裂くことができる。これにより、剥離フィルム層１１２を切り裂きながら剥離させる作業を円滑に行うことができるため、作業性が向上する。 In particular, in this embodiment, since the edge 114a of the protrusion 114 extends from the one end edge 112a of the release film layer 112 to the other end edge 112b, the protrusion 114 protrudes from the one end edge 112a or the other end edge 112b of the release film layer 112. A cut can be easily made along the edge 114a of the portion 114. Moreover, since the edge part 114a of the convex part 114 has extended on the straight line, the peeling film layer 112 which made the cut can be cut straight easily easily. Thereby, since the operation | work which peels while peeling the peeling film layer 112 can be performed smoothly, workability | operativity improves.
　図５は、剥離フィルム層１１２を切り裂きながら剥離させる際の別の態様について説明するための平面図である。この例では、凸部１１４の縁部１１４ａに沿って、凸部１１４が固定されている側の剥離フィルム層１１２を切り裂きながら剥離させるような構成となっている。すなわち、剥離フィルム層１１２を剥離させる際には、剥離フィルム層１１２の一端縁１１２ａにおける凸部１１４の一部を摘まみ、凸部１１４の縁部１１４ａが延びる方向Ｄに沿って力を加えながら剥離させる。 FIG. 5 is a plan view for explaining another mode when the release film layer 112 is peeled while being cut. In this example, along the edge part 114a of the convex part 114, the peeling film layer 112 on the side where the convex part 114 is fixed is peeled while being cut. That is, when the release film layer 112 is peeled off, a part of the convex portion 114 at one end edge 112a of the release film layer 112 is picked and a force is applied along the direction D in which the edge portion 114a of the convex portion 114 extends. Remove.
　これにより、図５に示すように、凸部１１４の縁部１１４ａに沿って剥離フィルム層１１２の一端縁１１２ａが切り裂かれる。そして、縁部１１４ａが延びる方向Ｄに沿ってそのまま力を加えることにより、剥離フィルム層１１２を凸部１１４とともに一端縁１１２ａから他端縁１１２ｂまで切り裂きながら剥離させることができる。その結果、剥離フィルム層１１２の一部１１２ｅ（凸部１１４が固定されている部分）が除去され、この部分に対向する粘着層１１３が露出する。 Thereby, as shown in FIG. 5, the one end edge 112 a of the release film layer 112 is cut along the edge part 114 a of the convex part 114. Then, by applying a force as it is along the direction D in which the edge portion 114a extends, the release film layer 112 can be peeled off along with the convex portion 114 while tearing from the one end edge 112a to the other end edge 112b. As a result, a part 112e (part where the convex part 114 is fixed) of the release film layer 112 is removed, and the adhesive layer 113 facing this part is exposed.
　このとき剥離される剥離フィルム層１１２の一部１１２ｅは、剥離フィルム層１１２の全体の面積に対して、半分以下の面積に対応する部分であることが好ましく、１／３～１／４の面積に対応する部分であればより好ましい。なお、剥離フィルム層１１２は、一端縁１１２ａからではなく、他端縁１１２ｂから切り裂かれてもよい。 The part 112e of the release film layer 112 to be peeled at this time is preferably a part corresponding to an area less than half of the entire area of the release film layer 112, and an area of 1/3 to 1/4. It is more preferable if it is a part corresponding to. Note that the release film layer 112 may be cut from the other end edge 112b instead of from the one end edge 112a.
　以上の説明では、凸部１１４の縁部１１４ａが、基材フィルム層１１１の短辺に対して平行に延びるような構成について説明した。しかし、このような構成に限らず、凸部１１４の縁部１１４ａが、例えば基材フィルム層１１１の長辺に対して平行に延びていてもよい。また、剥離フィルム層１１２を切り裂きながら剥離させることができるような構成であれば、凸部１１４は上記のような形状に限らず、他の任意の形状に形成することができる。 In the above description, the configuration in which the edge portion 114a of the convex portion 114 extends in parallel to the short side of the base film layer 111 has been described. However, the configuration is not limited to this, and the edge portion 114 a of the convex portion 114 may extend in parallel to the long side of the base film layer 111, for example. Moreover, if it is the structure which can be made to peel while peeling the peeling film layer 112, the convex part 114 can be formed not only in the above shapes but in another arbitrary shape.
　図６は、本発明の別の実施形態に係る保護フィルム２０１の構成例を示した平面図である。また、図７は、図６における保護フィルム２０１のＢ－Ｂ断面図であり、保護フィルム２０１の一部のみを示している。本実施形態に係る保護フィルム２０１は、携帯電話機、ゲーム機又はタブレット端末などの各種機器のディスプレイに貼り合せられ、当該ディスプレイの表示領域を保護するためのディスプレイ用保護フィルムである。 FIG. 6 is a plan view showing a configuration example of a protective film 201 according to another embodiment of the present invention. FIG. 7 is a BB cross-sectional view of the protective film 201 in FIG. 6 and shows only a part of the protective film 201. The protective film 201 according to the present embodiment is a display protective film that is bonded to a display of various devices such as a mobile phone, a game machine, or a tablet terminal, and protects a display area of the display.
　保護フィルム２０１は、基材フィルム層２１１と剥離フィルム層２１２とが、粘着層２１３を介して積層されることにより構成されている。すなわち、基材フィルム層２１１の一方の面に粘着層２１３が形成され、粘着層２１３上に剥離フィルム層２１２が設けられている。基材フィルム層２１１の他方の面には、例えば光反射防止機能などの各種機能に応じた任意のフィルム層が積層されていてもよい。また、基材フィルム層２１１自体が、このような各種機能を有していてもよい。 The protective film 201 is configured by laminating a base film layer 211 and a release film layer 212 via an adhesive layer 213. That is, the adhesive layer 213 is formed on one surface of the base film layer 211, and the release film layer 212 is provided on the adhesive layer 213. On the other surface of the base film layer 211, for example, an arbitrary film layer corresponding to various functions such as a light reflection preventing function may be laminated. Moreover, the base film layer 211 itself may have such various functions.
　基材フィルム層２１１は、ディスプレイの表示領域を覆うことができる形状を有している。より具体的には、基材フィルム層２１１は、ディスプレイの表示領域と同一、又は、それよりも大きい形状を有している。この例では、基材フィルム層２１１が長方形状に形成されているが、ディスプレイの表示領域の形状に応じて、正方形状などの他の矩形状に形成されていてもよいし、矩形状に限らず円形や楕円形などの他の各種形状に形成されていてもよい。 The base film layer 211 has a shape that can cover the display area of the display. More specifically, the base film layer 211 has a shape that is the same as or larger than the display area of the display. In this example, the base film layer 211 is formed in a rectangular shape, but may be formed in another rectangular shape such as a square shape or the like, depending on the shape of the display area of the display. Instead, it may be formed in various other shapes such as a circle or an ellipse.
　粘着層２１３は、基材フィルム層２１１の一方の面の全体に形成されている。剥離フィルム層２１２は、基材フィルム層２１１よりも大きい形状を有しており、基材フィルム層２１１の周縁よりも外側に張り出した状態で積層されている。剥離フィルム層２１２は、例えば透明フィルムにより形成されており、図６の状態では、透明な剥離フィルム層２１２を通して裏側の基材フィルム層２１１が視認可能となっている。ただし、剥離フィルム層２１２は、基材フィルム層２１１と同一の形状であってもよく、透明でなくてもよい。 The adhesive layer 213 is formed on the entire one surface of the base film layer 211. The release film layer 212 has a shape larger than that of the base film layer 211, and is laminated in a state of protruding outward from the periphery of the base film layer 211. The release film layer 212 is formed of, for example, a transparent film. In the state shown in FIG. 6, the base film layer 211 on the back side is visible through the transparent release film layer 212. However, the release film layer 212 may have the same shape as the base film layer 211 or may not be transparent.
　剥離フィルム層２１２は、粘着層２１３に対して剥離可能となっている。したがって、剥離フィルム層２１２を剥離させて粘着層２１３を露出させ、当該粘着層２１３をディスプレイの表示領域に貼り合せることにより、表示領域を基材フィルム層２１１で覆って保護することができる。 The release film layer 212 can be peeled from the adhesive layer 213. Therefore, by peeling the release film layer 212 to expose the adhesive layer 213 and bonding the adhesive layer 213 to the display area of the display, the display area can be covered and protected by the base film layer 211.
　本実施形態では、剥離フィルム層２１２上の一部に凸部２１４が形成されている。当該凸部２１４は、剥離フィルム層２１２における基材フィルム層２１１に対向していない領域に形成されている。この例では、剥離フィルム層２１２の周縁部の一部に凸部２１４が形成されている。より具体的には、剥離フィルム層２１２の一端縁２１２ａから他端縁２１２ｂまで、基材フィルム層２１１の短辺に対して平行に延びる第１凸部２１４ａと、第１凸部２１４ａの両端から基材フィルム層２１１の長辺に対して平行に延びる１対の第２凸部２１４ｂとにより、Ｕ字状の凸部２１４が形成されている。 In this embodiment, the convex part 214 is formed in a part on the peeling film layer 212. The convex portion 214 is formed in a region of the release film layer 212 that does not face the base film layer 211. In this example, the convex part 214 is formed in a part of the peripheral part of the peeling film layer 212. More specifically, from one end edge 212a of the release film layer 212 to the other end edge 212b, a first protrusion 214a extending in parallel to the short side of the base film layer 211, and both ends of the first protrusion 214a. A U-shaped convex portion 214 is formed by a pair of second convex portions 214 b extending in parallel to the long side of the base film layer 211.
　図６及び図７に二点鎖線で示すように、保護フィルム２０１をディスプレイ１に貼り合せる際には、凸部２１４がディスプレイ１に係止されることにより位置決めされる。この例では、ディスプレイ１の外縁に沿って凸部２１４が係止されることにより、ディスプレイ１に対して短辺方向及び長辺方向への保護フィルム２０１の移動が規制されて位置決めされる。 6 and 7, when the protective film 201 is bonded to the display 1, the convex portion 214 is positioned by being locked to the display 1 as indicated by a two-dot chain line. In this example, the projection 214 is locked along the outer edge of the display 1, whereby the movement of the protective film 201 in the short side direction and the long side direction is restricted and positioned with respect to the display 1.
　より具体的には、１対の第２凸部２１４ｂは、ディスプレイ１の幅に対応する間隔で対向している。したがって、１対の第２凸部２１４ｂ間にディスプレイ１を配置することにより、これらの第２凸部２１４ｂをディスプレイ１の長辺に引っ掛けて、保護フィルム２０１の短辺方向への移動を規制することができる。また、第１凸部２１４ａをディスプレイ１の短辺に引っ掛けて、保護フィルム２０１の長辺方向への移動を規制することができる。このように、凸部２１４は、保護フィルム２０１が適用されるディスプレイ１の形状に対応する形状となっている。 More specifically, the pair of second convex portions 214 b are opposed to each other at an interval corresponding to the width of the display 1. Therefore, by disposing the display 1 between the pair of second convex portions 214b, the second convex portions 214b are hooked on the long sides of the display 1 to restrict the movement of the protective film 201 in the short side direction. be able to. Moreover, the 1st convex part 214a can be hooked on the short side of the display 1, and the movement to the long side direction of the protective film 201 can be controlled. Thus, the convex part 214 has a shape corresponding to the shape of the display 1 to which the protective film 201 is applied.
　凸部２１４は、例えば打ち抜き加工により形成することができる。すなわち、剥離フィルム層２１２上に別のフィルム層を接着した後、そのフィルム層における凸部２１４を形成しようとする部分以外の部分を打ち抜いて除去することにより、残った部分に凸部２１４を形成することができる。例えば凸部２１４が色付けされていれば、凸部２１４の位置が分かりやすいため、保護フィルム２０１を円滑に位置決めすることができる。 The convex portion 214 can be formed by punching, for example. That is, after another film layer is bonded onto the release film layer 212, a portion other than the portion where the convex portion 214 is to be formed is punched and removed to form the convex portion 214 in the remaining portion. can do. For example, if the convex part 214 is colored, since the position of the convex part 214 is easy to understand, the protective film 201 can be positioned smoothly.
　剥離フィルム層２１２の厚みは、例えば５０～１００μｍ程度であることが好ましい。凸部２１４の厚みは、剥離フィルム層２１２の厚みよりも大きいことが好ましく、例えば５００μｍ以上であることが好ましい。剥離フィルム層２１２の厚みに対する凸部２１４の厚みは、例えば１０～４０倍であることが好ましく、２０～４０倍であればより好ましい。 The thickness of the release film layer 212 is preferably about 50 to 100 μm, for example. The thickness of the convex portion 214 is preferably larger than the thickness of the release film layer 212, and is preferably 500 μm or more, for example. The thickness of the projection 214 with respect to the thickness of the release film layer 212 is preferably 10 to 40 times, for example, and more preferably 20 to 40 times.
　基材フィルム層２１１、剥離フィルム層２１２及び粘着層２１３は、保護フィルムにおいて一般的に使用されている公知の材料により形成することができる。凸部２１４は、剥離フィルム層２１２と同じ材料で形成されていてもよいし、異なる材料で形成されていてもよい。 The base film layer 211, the release film layer 212, and the adhesive layer 213 can be formed of a known material that is generally used in a protective film. The convex part 214 may be formed with the same material as the peeling film layer 212, and may be formed with a different material.
　ただし、凸部２１４は、図６及び図７に例示されたような形状に限らず、例えば剥離フィルム層２１２の全周にわたって形成されていてもよいし、剥離フィルム層２１２の周縁部に沿って部分的に形成されることにより、複数の凸部２１４が断続的に設けられた構成であってもよい。また、凸部２１４は、剥離フィルム層２１２と一体的に形成されていてもよい。 However, the convex 214 is not limited to the shape illustrated in FIGS. 6 and 7, and may be formed, for example, over the entire circumference of the release film layer 212, or along the peripheral edge of the release film layer 212. A configuration in which the plurality of convex portions 214 are provided intermittently by being partially formed may be used. Moreover, the convex part 214 may be formed integrally with the peeling film layer 212.
　剥離フィルム層２１２における凸部２１４が形成されていない領域には、例えば切込み２１５が形成されている。切込み２１５は、剥離フィルム層２１２の一端縁２１２ａから他端縁２１２ｂまで一直線上に延びており、これにより、剥離フィルム層２１２が２分割されている。この切込み２１５に沿って剥離フィルム層２１２を一端縁２１２ａ又は他端縁２１２ｂから剥離させれば、剥離フィルム層２１２の一部２１２ｃが除去され、この部分に対応する粘着層２１３が露出する。 For example, a cut 215 is formed in a region of the release film layer 212 where the convex portion 214 is not formed. The notch 215 extends in a straight line from the one end edge 212a to the other end edge 212b of the release film layer 212, whereby the release film layer 212 is divided into two. If the release film layer 212 is peeled from the one end edge 212a or the other end edge 212b along the notch 215, a part 212c of the release film layer 212 is removed, and the adhesive layer 213 corresponding to this part is exposed.
　図８Ａ～図８Ｃは、図６の保護フィルム２０１をディスプレイ１の表示領域２に貼り合せる際の態様について説明するための概略断面図である。上記のような態様で、剥離フィルム層２１２における凸部２１４が形成されていない側の一部２１２ｃが剥離された後、保護フィルム２０１は、ディスプレイ１の表示領域２に対して位置合わせされる。 8A to 8C are schematic cross-sectional views for explaining an aspect when the protective film 201 of FIG. 6 is bonded to the display region 2 of the display 1. After the part 212c on the side where the convex part 214 is not formed in the release film layer 212 is peeled in the manner as described above, the protective film 201 is aligned with the display area 2 of the display 1.
　このとき、露出した粘着層２１３がディスプレイ１の表示領域２に対向するようにして、粘着層２１３を表示領域２から離した状態で保護フィルム１０１を移動させる。そして、図８Ａに示すように、凸部２１４をディスプレイ１の外縁に沿って係止させることにより位置決めした上で、図８Ｂに示すように、露出している粘着層２１３を表示領域２に貼り合せる。ただし、図４Ａ～図４Ｃの凸部１１４のように、剥離フィルム層２１２の表面に凸部を設けて、当該凸部の表面を表示領域２に摺接させながら、保護フィルム２０１を水平方向に移動させて位置合わせを行うことも可能である。 At this time, the protective film 101 is moved in a state where the adhesive layer 213 is separated from the display region 2 so that the exposed adhesive layer 213 faces the display region 2 of the display 1. Then, as shown in FIG. 8A, after positioning the protrusion 214 along the outer edge of the display 1, the exposed adhesive layer 213 is pasted on the display area 2 as shown in FIG. 8B. Match. However, like the convex portion 114 in FIGS. 4A to 4C, a convex portion is provided on the surface of the release film layer 212, and the protective film 201 is placed in the horizontal direction while the surface of the convex portion is in sliding contact with the display region 2. It is also possible to perform alignment by moving.
　その後、剥離フィルム層２１２の残りの部分を切込み２１５側から剥離させ、図８Ｃに示すように、剥離フィルム層２１２を反転させて引き抜きながら、粘着層２１３の残りの部分を表示領域２に貼り合せる。このようにして、粘着層２１３全体を表示領域２に貼り合せることができる。 Thereafter, the remaining part of the release film layer 212 is peeled off from the cut 215 side, and as shown in FIG. 8C, the remaining part of the adhesive layer 213 is bonded to the display area 2 while the release film layer 212 is reversed and pulled out. . In this way, the entire adhesive layer 213 can be bonded to the display area 2.
　ただし、剥離フィルム層２１２の一部２１２ｃを予め剥離した後に保護フィルム２０１を位置決めするような態様ではなく、保護フィルム２０１を位置決めした後、剥離フィルム層２１２の一部２１２ｃを剥離して、露出した粘着層２１３を表示領域２に貼り合せてもよい。この場合は、保護フィルム２０１の一端部を凸部２１４によりディスプレイ１の外縁に係止させた状態のまま、保護フィルム２０１の他端部をめくり上げて、剥離フィルム層２１２の一部２１２ｃを剥離すればよい。 However, it is not an embodiment in which the protective film 201 is positioned after the part 212c of the peeling film layer 212 is peeled in advance, and after the protective film 201 is positioned, the part 212c of the peeling film layer 212 is peeled and exposed. The adhesive layer 213 may be bonded to the display area 2. In this case, the other end portion of the protective film 201 is turned up while the one end portion of the protective film 201 is locked to the outer edge of the display 1 by the convex portion 214, and the part 212c of the release film layer 212 is peeled off. do it.
　以上のように、本実施形態では、剥離フィルム層２１２上に形成された凸部２１４をディスプレイ１に係止させて位置決めした状態で、凸部２１４とは異なる領域で剥離フィルム層２１２を剥離させることにより露出した粘着層２１３の一部を表示領域２に貼り合せることができる。その後、凸部２１４を含む領域で残りの剥離フィルム層２１２を剥離させることにより、粘着層２１３の残りの部分を露出させ、表示領域２に貼り合せることができる。これにより、剥離フィルム層２１２上に形成された凸部２１４をディスプレイ１に係止させるだけの簡単な構成で、保護フィルム２０１を正確な位置に容易に貼り合せることができる。 As described above, in the present embodiment, the release film layer 212 is peeled in a region different from the protrusions 214 in a state where the protrusions 214 formed on the release film layer 212 are locked and positioned on the display 1. Thus, a part of the adhesive layer 213 exposed can be bonded to the display area 2. Thereafter, the remaining release film layer 212 is peeled off in the region including the convex portion 214, so that the remaining portion of the adhesive layer 213 can be exposed and bonded to the display region 2. Thereby, the protective film 201 can be easily bonded to an accurate position with a simple configuration in which the convex portion 214 formed on the release film layer 212 is simply locked to the display 1.
　特に、本実施形態では、剥離フィルム層２１２上に形成された凸部２１４を、ディスプレイ１の外縁に沿って容易に係止させることができる。すなわち、凸部２１４を係止させるための部分をディスプレイ１側に別途設けることなく、ディスプレイ１の外縁を利用して凸部２１４を係止させることができるため、より簡単な構成で保護フィルム２０１を容易に貼り合せることができる。 In particular, in the present embodiment, the convex portion 214 formed on the release film layer 212 can be easily locked along the outer edge of the display 1. That is, the projection 214 can be locked using the outer edge of the display 1 without separately providing a portion for locking the projection 214 on the display 1 side, so that the protective film 201 can be configured with a simpler configuration. Can be easily pasted together.
　図９は、図６の保護フィルム２０１の変形例を示した平面図である。また、図１０は、図９における保護フィルム２０１のＣ－Ｃ断面図であり、保護フィルム２０１の一部のみを示している。この例では、凸部２１４の形状及び切込み２１５の形成位置が図６の場合とは異なり、他の構成については図６の場合と同様であるため、同様の構成については、図に同一符号を付して詳細な説明を省略する。 FIG. 9 is a plan view showing a modification of the protective film 201 of FIG. FIG. 10 is a cross-sectional view taken along the line CC of the protective film 201 in FIG. 9 and shows only a part of the protective film 201. In this example, the shape of the convex portion 214 and the formation position of the notch 215 are different from those in FIG. 6, and the other configurations are the same as those in FIG. 6. Detailed description will be omitted.
　この例では、凸部２１４がディスプレイ１の外縁に沿って係止されるのではなく、ディスプレイ１の表面に形成されている凹部に係止されるようになっている。凸部２１４を係止させるための凹部としては、ディスプレイ１に形成されているスピーカ、マイク又はヘッドホンなどのための各種凹部を利用することができる。ディスプレイ１における上記凹部が形成された表面は、表示領域２が形成されている面であってもよいし、ディスプレイ１の側面などのように、表示領域２が形成されていない面であってもよい。 In this example, the convex portion 214 is not locked along the outer edge of the display 1 but is locked in a concave portion formed on the surface of the display 1. As a recess for locking the projection 214, various recesses for a speaker, a microphone, a headphone, or the like formed in the display 1 can be used. The surface of the display 1 on which the concave portion is formed may be a surface on which the display region 2 is formed, or may be a surface on which the display region 2 is not formed, such as a side surface of the display 1. Good.
　凸部２１４は、剥離フィルム層２１２における基材フィルム層２１１に対向していない領域に形成されている。この例では、剥離フィルム層２１２の周縁部の一部に凸部２１４が形成されている。より具体的には、剥離フィルム層２１２の短辺に沿った中央部に、横長の凸部２１４が形成されている。ただし、凸部２１４の形状及び位置は、ディスプレイ１に形成されている凹部の形状及び位置に応じて任意に設定することができる。 The convex portion 214 is formed in a region of the release film layer 212 that does not face the base film layer 211. In this example, the convex part 214 is formed in a part of the peripheral part of the peeling film layer 212. More specifically, a horizontally long convex portion 214 is formed at the central portion along the short side of the release film layer 212. However, the shape and position of the convex portion 214 can be arbitrarily set according to the shape and position of the concave portion formed in the display 1.
　凸部２１４は、図６の場合と同様に、例えば打ち抜き加工により形成することができる。また、図６の場合と同様に、凸部２１４が色付けされていてもよい。さらに、剥離フィルム層２１２及び凸部２１４の厚みや材料についても、図６の場合と同様の態様で設定することができる。 The convex portion 214 can be formed by punching, for example, as in the case of FIG. Moreover, the convex part 214 may be colored similarly to the case of FIG. Further, the thickness and material of the release film layer 212 and the convex portion 214 can be set in the same manner as in the case of FIG.
　この例では、切込み２１５が１つではなく、複数設けられている。具体的には、互いに平行に延びる１対の切込み２１５が、それぞれ剥離フィルム層２１２の一端縁２１２ａから他端縁２１２ｂまで一直線上に延びており、これにより、剥離フィルム層２１２が３分割されている。これらの切込み２１５に沿って剥離フィルム層２１２を一端縁２１２ａ又は他端縁２１２ｂから剥離させれば、剥離フィルム層２１２の中央部２１２ｄを除去し、この部分に対応する粘着層２１３を露出させることができる。このように、切込み２１５の数及び位置は、任意に設定することができる。 In this example, a plurality of cuts 215 are provided instead of one. Specifically, a pair of cuts 215 extending in parallel with each other extend in a straight line from one end edge 212a to the other end edge 212b of the release film layer 212, whereby the release film layer 212 is divided into three parts. Yes. If the release film layer 212 is peeled from the one end edge 212a or the other end edge 212b along these notches 215, the central portion 212d of the release film layer 212 is removed, and the adhesive layer 213 corresponding to this part is exposed. Can do. Thus, the number and position of the cuts 215 can be arbitrarily set.
　図１１Ａ～図１１Ｃは、図９の保護フィルム２０１をディスプレイ１の表示領域２に貼り合せる際の態様について説明するための概略断面図である。上記のような態様で、剥離フィルム層２１２の中央部２１２ｄが剥離された後、保護フィルム２０１は、ディスプレイ１の表示領域２に対して位置合わせされる。 FIGS. 11A to 11C are schematic cross-sectional views for explaining an aspect when the protective film 201 of FIG. 9 is bonded to the display region 2 of the display 1. After the central portion 212 d of the release film layer 212 is peeled in the manner as described above, the protective film 201 is aligned with the display area 2 of the display 1.
　このとき、露出した粘着層２１３がディスプレイ１の表示領域２に対向するようにして、粘着層２１３を表示領域２から離した状態で保護フィルム１０１を移動させる。そして、凸部２１４をディスプレイ１の凹部３に挿入して係止させることにより位置決めした上で、図１１Ａに示すように、露出している粘着層２１３を表示領域２に貼り合せる。 At this time, the protective film 101 is moved in a state where the adhesive layer 213 is separated from the display region 2 so that the exposed adhesive layer 213 faces the display region 2 of the display 1. Then, after positioning the convex portion 214 by inserting it into the concave portion 3 of the display 1 and locking it, the exposed adhesive layer 213 is bonded to the display region 2 as shown in FIG. 11A.
　その後、剥離フィルム層２１２における一端側の部分を切込み２１５側から剥離させ、図１１Ｂに示すように、剥離フィルム層２１２を反転させて引き抜きながら、粘着層２１３の露出した部分を表示領域２に貼り合せる。さらに、剥離フィルム層２１２における他端側の残りの部分を切込み２１５側から剥離させ、図１１Ｃに示すように、剥離フィルム層２１２を反転させて引き抜きながら、粘着層２１３の残りの部分を表示領域２に貼り合せる。このようにして、粘着層２１３全体を表示領域２に貼り合せることができる。 Thereafter, the part on one end side of the release film layer 212 is peeled off from the notch 215 side, and the exposed part of the adhesive layer 213 is pasted on the display area 2 while being reversed and pulled out as shown in FIG. 11B. Match. Further, the remaining portion on the other end side of the release film layer 212 is peeled off from the cut 215 side, and the remaining portion of the adhesive layer 213 is displayed in the display area while the release film layer 212 is reversed and pulled out as shown in FIG. 11C. Paste to 2. In this way, the entire adhesive layer 213 can be bonded to the display area 2.
　ただし、剥離フィルム層２１２の中央部２１２ｄを予め剥離した後に保護フィルム２０１を位置決めするような態様ではなく、保護フィルム２０１を位置決めした後、剥離フィルム層２１２の中央部２１２ｄを剥離して、露出した粘着層２１３を表示領域２に貼り合せてもよい。この場合は、保護フィルム２０１の一端部を凸部２１４によりディスプレイ１の凹部３に係止させた状態のまま、保護フィルム２０１の他端部をめくり上げて、剥離フィルム層２１２の中央部２１２ｄを剥離すればよい。 However, it is not an aspect in which the protective film 201 is positioned after the central portion 212d of the release film layer 212 is previously peeled off, and after the protective film 201 is positioned, the central portion 212d of the release film layer 212 is released and exposed. The adhesive layer 213 may be bonded to the display area 2. In this case, the other end portion of the protective film 201 is turned up while the one end portion of the protective film 201 is locked to the concave portion 3 of the display 1 by the convex portion 214, and the central portion 212d of the release film layer 212 is removed. It can be peeled off.
　以上のように、図９～図１１Ｃの例では、剥離フィルム層２１２上に形成された凸部２１４を、ディスプレイ１の表面に形成されている凹部３に容易に係止させることができる。この場合、スピーカ、マイク又はヘッドホンなどのためにディスプレイ１の表面に形成されている凹部３を利用すれば、凸部２１４を係止させるための部分をディスプレイ１側に別途設ける必要がないため、より簡単な構成で保護フィルム２０１を容易に貼り合せることができる。 As described above, in the example of FIGS. 9 to 11C, the convex portion 214 formed on the release film layer 212 can be easily locked to the concave portion 3 formed on the surface of the display 1. In this case, if the concave portion 3 formed on the surface of the display 1 is used for a speaker, a microphone, a headphone, or the like, there is no need to separately provide a portion for locking the convex portion 214 on the display 1 side. The protective film 201 can be easily bonded with a simpler configuration.
