剝離膠帶及具備其之液晶面板、液晶模組 Stripping tape and liquid crystal panel and liquid crystal module therewith

本發明係有關液晶面板的偏光板上貼附之保護膜的剝離膠帶及具備其之液晶面板、液晶模組。 The present invention relates to a release tape for a protective film attached to a polarizing plate of a liquid crystal panel, and a liquid crystal panel and a liquid crystal module including the same.

習知,在汽車的儀表(裝置面板)上搭載之時鐘顯示部、多重資訊顯示部、導航顯示部、音響顯示部等,會使用液晶面板100。該液晶面板100之一例如圖6所示。圖6(A)為表面圖(正面圖)、圖6(B)為側面圖、圖6(C)為截面圖。 It is known that the liquid crystal panel 100 is used in a clock display unit, a multi-information display unit, a navigation display unit, an audio display unit, and the like mounted on a meter (device panel) of a car. One of the liquid crystal panels 100 is as shown in Fig. 6, for example. 6(A) is a front view (front view), FIG. 6(B) is a side view, and FIG. 6(C) is a cross-sectional view.

如圖6(A)、圖6(B)、圖6(C)所示,液晶面板100是由表裏2片透明的基板101、及包夾於該基板101間的液晶材料106、及設置於該基板101的更外側之表裏2片偏光板107,所構成。透明的基板,例如會使用玻璃基板101。在該玻璃基板101一方之表面依序形成透明電極102及配向膜103,並將配向膜103呈上下面對面的2片玻璃基板101,隔著間隔材104藉由密封材105等平行地貼合,以使基板間距離成為均一。接著,在基板間封入向列(nematic)液晶等液晶材料106,並在玻 璃基板101的更外側貼附偏光板107而製造出來。液晶面板100當中,有些會設置彩色濾光片而使其可顯示顏色。該液晶面板100會視需要,而如圖6(A)、圖6(B)的假想線所示,在裏側的基板101上組裝液晶面板100的驅動用IC201、FPC用連接器202、訊號入輸出用FPC203等,藉此裝配於液晶模組200。此外,在液晶模組200亦會視需要而裝配未圖示之光源(背光、側光、前光)等。 As shown in FIG. 6(A), FIG. 6(B), and FIG. 6(C), the liquid crystal panel 100 is provided by two transparent substrates 101 in the front and back, and a liquid crystal material 106 interposed between the substrates 101, and The substrate 101 has two polarizing plates 107 on the outer side of the substrate 101. For the transparent substrate, for example, the glass substrate 101 is used. The transparent electrode 102 and the alignment film 103 are sequentially formed on one surface of the glass substrate 101, and the alignment film 103 is placed on the surface of the glass substrate 101 in the upper and lower faces, and the spacers 104 are bonded in parallel via the sealing member 105 or the like. In order to make the distance between the substrates uniform. Next, a liquid crystal material 106 such as a nematic liquid crystal is sealed between the substrates, and is in a glass The polarizing plate 107 is attached to the outer side of the glass substrate 101 to be manufactured. Among the liquid crystal panels 100, some of them are provided with color filters so that they can display colors. As shown in the imaginary lines of FIGS. 6(A) and 6(B), the liquid crystal panel 100 is assembled with the driving IC 201, the FPC connector 202, and the signal input of the liquid crystal panel 100 on the back substrate 101. The output is assembled to the liquid crystal module 200 by using the FPC 203 or the like. Further, a light source (backlight, side light, front light) or the like (not shown) is attached to the liquid crystal module 200 as needed.

偏光板107係比液晶面板100的顯示區域還大,且比玻璃基板101還小,而貼附於玻璃基板101,以使玻璃基板101露出於偏光板107的周圍。 The polarizing plate 107 is larger than the display region of the liquid crystal panel 100 and smaller than the glass substrate 101, and is attached to the glass substrate 101 so that the glass substrate 101 is exposed around the polarizing plate 107.

此外,在偏光板107一方之表面(基板側之表面),隔著黏著劑層108而貼附有未圖示之離型膜。該離型膜在將偏光板107貼附於玻璃基板101的階段會被剝離,而偏光板107會藉由黏著劑層108貼附於玻璃基板101。 Further, on the surface (the surface on the substrate side) of one of the polarizing plates 107, a release film (not shown) is attached via the adhesive layer 108. The release film is peeled off at the stage of attaching the polarizing plate 107 to the glass substrate 101, and the polarizing plate 107 is attached to the glass substrate 101 by the adhesive layer 108.

又,在偏光板107另一方之表面(與基板相反側之表面),隔著黏著劑層110而貼附有透明的保護膜109。該保護膜109是用來在液晶面板100製造時或液晶模組200組裝時防止偏光板107的損傷,但完成的液晶面板100或液晶模組200會在貼附有保護膜109的狀態下出貨,而由使用者剝離保護膜109。 Further, on the other surface (surface opposite to the substrate) of the polarizing plate 107, a transparent protective film 109 is attached via the adhesive layer 110. The protective film 109 is used to prevent damage of the polarizing plate 107 when the liquid crystal panel 100 is manufactured or when the liquid crystal module 200 is assembled. However, the completed liquid crystal panel 100 or the liquid crystal module 200 is attached with the protective film 109 attached thereto. The product is peeled off by the user.

另,偏光板107若為穿透式面板用,則在表裏面用皆會貼附保護膜109,但若為半穿透式面板的裏面用,有時會取代保護膜109而隔著黏著劑層貼附半透明之 反射板,若為反射型面板的裏面用,有時會取代保護膜109而隔著黏著劑層112貼附反射板111。反射型面板的裏面用,如圖6(B)、圖6(C)所示。 In addition, if the polarizing plate 107 is a transmissive panel, the protective film 109 is attached to the inside of the watch, but if it is used for the inside of the transflective panel, the protective film 109 may be replaced by the adhesive. Layer attached with translucency When the reflector is used for the inside of the reflective panel, the reflector 111 may be attached via the adhesive layer 112 instead of the protective film 109. The inside of the reflective panel is as shown in Fig. 6(B) and Fig. 6(C).

不過,偏光板107與保護膜109之間的黏著,除了它們之間的黏著劑層110造成的黏著力以外,在保護膜109的兩面產生之差壓所致之黏著力亦發揮作用,故非常強,需要很大的力來剝離保護膜109。但,在保護膜109的端部,由於偏光板107與保護膜109之間空氣能夠輕易地進入,故差壓所致之黏著力會喪失,只要有黏著劑層110造成的黏著力以上的力,便能剝離保護膜109。而一旦能夠剝離保護膜109端部的至少一部分,那麼以此為開端,空氣便能連續地進入偏光板107與保護膜109之間,藉由黏著劑層110造成的黏著力以上的力,便能剝離剩下所有的保護膜109。 However, the adhesion between the polarizing plate 107 and the protective film 109, in addition to the adhesion caused by the adhesive layer 110 therebetween, the adhesion caused by the differential pressure generated on both sides of the protective film 109 also functions, so Strong, a large force is required to peel off the protective film 109. However, at the end of the protective film 109, since the air can easily enter between the polarizing plate 107 and the protective film 109, the adhesive force due to the differential pressure is lost, as long as the adhesive force of the adhesive layer 110 is greater than the adhesive force. The protective film 109 can be peeled off. Once at least a portion of the end of the protective film 109 can be peeled off, the air can continuously enter between the polarizing plate 107 and the protective film 109, and the adhesive force of the adhesive layer 110 is greater than the adhesive force. All of the protective film 109 remaining can be peeled off.

是故,欲剝離保護膜109,係廣泛使用黏著膠帶,其具有之黏著力為偏光板107與保護膜109之間的黏著劑層110造成的黏著力以上。該黏著膠帶,在液晶面板100製造工程當中於偏光板107的貼附工程以後,會以包含保護膜109端部至少一部分的方式貼附於保護膜109,完成的液晶面板100或液晶模組200,會以貼附有保護膜109及其剝離用黏著膠帶的狀態下出貨,以便使用者藉由將黏著膠帶朝規定方向拉扯,便能夠不損傷偏光板107而剝離保護膜109。該黏著膠帶稱為剝離膠帶。該剝離膠帶的習知例,如圖7所示具有專利文獻1所揭示構造之習知 的剝離膠帶1。圖7(A)為側面圖、圖7(B)為裏面圖(背面圖)。 Therefore, in order to peel off the protective film 109, an adhesive tape is widely used, which has an adhesive force which is higher than the adhesive force of the adhesive layer 110 between the polarizing plate 107 and the protective film 109. After the adhesive tape is attached to the polarizing plate 107 in the manufacturing process of the liquid crystal panel 100, the adhesive tape is attached to the protective film 109 so as to include at least a part of the end portion of the protective film 109, and the completed liquid crystal panel 100 or the liquid crystal module 200 is completed. The protective film 109 and its adhesive tape for peeling are attached so that the user can pull the protective film 109 without damaging the polarizing plate 107 by pulling the adhesive tape in a predetermined direction. This adhesive tape is called a release tape. A conventional example of the release tape has a conventional structure disclosed in Patent Document 1 as shown in FIG. Stripping tape 1. Fig. 7(A) is a side view, and Fig. 7(B) is a rear view (rear view).

如圖7(A)、圖7(B)所示,剝離膠帶1是由:片狀的黏著部4,形成於剝離膠帶1長邊方向(左右方向)一方的端部即左端部,外形形狀為長方形;及片狀的非黏著部5,形成於剝離膠帶1長邊方向另一方的端部即右端部,外形形狀為長方形;所構成。具體而言,由片狀樹脂膜所構成之外形形狀為長方形的一片基材(膠帶本體)2當中,僅在從長邊方向(左右方向)左端至中途為止的長方形(寛度與膠帶寛度相同,長度比膠帶長還短之長方形)的區域裏面,形成比偏光板107與保護膜109之間的黏著劑層110造成的黏著力還具有更強力黏著力之黏著劑層3,藉此,在剝離膠帶1左端部會形成外形形狀為長方形之片狀的黏著部4。另一方面,在從基材2長邊方向右端至中途為止的剩餘長方形(寛度與膠帶寛度相同,長度比膠帶長還短之長方形)的區域裏面,並未形成黏著劑層3,藉此,在剝離膠帶1右端部會形成外形形狀為長方形之片狀的非黏著部5。此外,在剝離膠帶1長邊方向的中途,垂直跨越剝離膠帶1寬幅方向的上下側端緣間,且構成黏著劑層3長邊方向右側端緣的一條直線,會成為黏著部4與非黏著部5之間的交界線6,顯現於剝離膠帶1的裏面側。將該剝離膠帶1貼附於保護膜109狀態下之液晶面板100,如圖8所示。圖8(A)為表面圖(正面圖)、圖8(B)為截面圖。此外,圖8(A)、圖8(B) 中,比表側的玻璃基板101還裏側之構造是以透明化狀態表示。又,圖8(B)中,貼附有剝離膠帶1的部分是以放大狀態表示。 As shown in Fig. 7 (A) and Fig. 7 (B), the release tape 1 is formed by a sheet-shaped adhesive portion 4, which is formed at the end portion of the longitudinal direction (left-right direction) of the release tape 1, that is, the left end portion, and the outer shape. The rectangular shape and the sheet-shaped non-adhesive portion 5 are formed at the right end portion of the other end in the longitudinal direction of the release tape 1 and have a rectangular outer shape. Specifically, among the one base material (tape main body) 2 which is formed into a rectangular shape and formed of a sheet-like resin film, the rectangular shape (twist and tape width) is only in the longitudinal direction (left-right direction) from the left end to the middle. In the region of the same rectangular shape whose length is shorter than the length of the tape, the adhesive layer 3 having a stronger adhesive force than the adhesive layer 110 between the polarizing plate 107 and the protective film 109 is formed, whereby At the left end portion of the release tape 1, an adhesive portion 4 having a rectangular outer shape is formed. On the other hand, in the region from the right end in the longitudinal direction of the substrate 2 to the middle of the substrate (the rectangle having the same twist and tape width and shorter than the tape length), the adhesive layer 3 is not formed. Thus, a non-adhesive portion 5 having a rectangular outer shape is formed at the right end portion of the release tape 1. Further, in the middle of the longitudinal direction of the release tape 1, the straight line spans between the upper and lower end edges in the width direction of the release tape 1 and a straight line constituting the right end edge of the adhesive layer 3 in the longitudinal direction becomes the adhesive portion 4 and The boundary line 6 between the adhesive portions 5 appears on the back side of the release tape 1. The release tape 1 is attached to the liquid crystal panel 100 in a state of the protective film 109 as shown in FIG. 8(A) is a surface view (front view) and FIG. 8(B) is a cross-sectional view. In addition, Figure 8 (A), Figure 8 (B) In the middle, the structure on the back side of the glass substrate 101 on the front side is represented by a transparent state. Further, in Fig. 8(B), the portion to which the release tape 1 is attached is shown in an enlarged state.

如圖8(A)、圖8(B)所示,剝離膠帶1在考量經濟性下係比保護膜109還充分小(窄而短),例如隔著黏著部4貼附於保護膜109一方之端部即右端部,使得黏著部4覆蓋在保護膜109長邊方向一方之端緣即右側端緣,且非黏著部5從保護膜109朝右側伸出。此外,在貼附該剝離膠帶1之際,雖然可以將黏著部4與非黏著部5之間的交界線6切齊保護膜109的右側端緣,將黏著部4的右側端緣重疊於保護膜109的右側端緣,但基於後述理由,係以稍微取一留白M的狀態來貼附,使得黏著部4的右側端部從保護膜109的右側端緣朝更右側伸出。又,當使用者剝離保護膜109時,將剝離膠帶1的非黏著部5如圖8(B)箭頭所示朝左斜上方(相對於偏光板107呈150度之角度)拉扯,藉此,相較於偏光板107與保護膜109之間的黏著劑層110造成的黏著力,黏著部4的黏著劑層3造成的黏著力較強,且在保護膜109的右側端緣覆蓋著黏著部4,故如圖8(B)假想線所示,能夠與剝離膠帶1成為一體而剝離保護膜109的右端部,並以該處為開端,能夠連續地剝離所有保護膜109。 As shown in FIGS. 8(A) and 8(B), the release tape 1 is sufficiently smaller (narrower and shorter) than the protective film 109 in consideration of economy, for example, attached to the protective film 109 via the adhesive portion 4. The end portion, that is, the right end portion, is such that the adhesive portion 4 covers the end edge of one side in the longitudinal direction of the protective film 109, that is, the right end edge, and the non-adhesive portion 5 projects from the protective film 109 toward the right side. Further, when the release tape 1 is attached, the boundary line 6 between the adhesive portion 4 and the non-adhesive portion 5 can be aligned with the right end edge of the protective film 109, and the right end edge of the adhesive portion 4 is overlapped and protected. The right end edge of the film 109 is attached in a state in which a white M is slightly removed for the reason described later, so that the right end portion of the adhesive portion 4 protrudes from the right end edge of the protective film 109 toward the right side. Further, when the user peels off the protective film 109, the non-adhesive portion 5 of the release tape 1 is pulled obliquely upward (at an angle of 150 degrees with respect to the polarizing plate 107) as indicated by an arrow in Fig. 8(B), whereby The adhesive force of the adhesive layer 3 of the adhesive portion 4 is stronger than that of the adhesive layer 110 between the polarizing plate 107 and the protective film 109, and the adhesive portion of the protective film 109 is covered with the adhesive portion. 4, as shown in the imaginary line of FIG. 8(B), the right end portion of the protective film 109 can be peeled off integrally with the release tape 1, and at this point, the entire protective film 109 can be continuously peeled off.

不過,在圖6(A)、圖6(B)、圖6(C)、圖8(A)、圖8(B)中,係揭示相對於玻璃基板101而言貼附在正確位置的偏光板107,但由於液晶面 板100各製造工程的誤差等,相對於玻璃基板101,有時偏光板107會貼附在稍微偏離正確位置的位置(但,該偏差量在無需重貼之容許範圍內)。圖9、圖10揭示,相對於玻璃基板101,偏光板107貼附在從正確位置朝剝離膠帶1貼附位置側即右側偏離的位置之情形。此外,圖9揭示於貼附剝離膠帶1時未取留白M之情形、圖10揭示於貼附剝離膠帶1時有取留白M之情形。圖9(A)、圖10(A)為相當於圖8(A)之表面圖(正面圖),圖9(B)、圖10(B)為相當於圖8(B)之截面圖。圖9(A)、圖10(A)的假想線,表示偏光板107的正確貼附位置。 However, in FIGS. 6(A), 6(B), 6(C), 8(A), and 8(B), the polarized light attached to the correct position with respect to the glass substrate 101 is disclosed. Plate 107, but due to the LCD surface The error of the manufacturing process of the board 100, etc. may be attached to the glass substrate 101 at a position slightly deviated from the correct position with respect to the glass substrate 101 (however, the amount of the deviation is within an allowable range in which re-attachment is not required). In the case of the glass substrate 101, the polarizing plate 107 is attached to a position deviated from the correct position toward the side where the peeling tape 1 is attached, that is, the right side. In addition, FIG. 9 discloses a case where the white M is not removed when the release tape 1 is attached, and FIG. 10 discloses a case where the white M is removed when the release tape 1 is attached. 9(A) and 10(A) are surface views (front view) corresponding to Fig. 8(A), and Figs. 9(B) and 10(B) are cross-sectional views corresponding to Fig. 8(B). The imaginary line of FIG. 9(A) and FIG. 10(A) shows the correct attachment position of the polarizing plate 107.

如圖9(A)、圖9(B)、圖10(A)、圖10(B)所示,當偏光板107貼附在從正確位置朝右側偏離的位置之情形下,如圖9(A)、圖9(B)所示,於貼附剝離膠帶1之際,若未在右側取留白M的情況下,黏著部4不會覆蓋在偏光板107的右側端緣亦即保護膜109的右側端緣,而喪失直接剝離保護膜109的契機,雖然黏著部4的黏著劑層3比偏光板107與保護膜109之間的黏著劑層110造成的黏著力具有更強力的黏著力,但在偏光板107與保護膜109之間,除了該處的黏著劑層110造成的黏著力以外,在保護膜109的兩面產生之差壓所致之黏著力亦發揮作用,故會如圖9(B)假想線所示,無法剝離保護膜109,而僅剝離了剝離膠帶1,導致問題。相對於此,如圖10(A)、圖10(B)所示,於貼附剝離膠帶 1之際,當在右側有取留白M的情況下,能夠將黏著部4覆蓋於保護膜的右側端緣,製造剝離保護膜109的契機,便如圖10(B)假想線所示,會與剝離膠帶1成為一體而能夠剝離保護膜109的右端部,並以該處為開端,能夠連續地剝離所有保護膜109。 As shown in FIG. 9(A), FIG. 9(B), FIG. 10(A), and FIG. 10(B), when the polarizing plate 107 is attached to a position deviated from the correct position to the right side, as shown in FIG. 9 ( A) and FIG. 9(B), when the peeling tape 1 is attached, if the white M is not left on the right side, the adhesive portion 4 does not cover the right end edge of the polarizing plate 107, that is, the protective film. The right end edge of 109 loses the opportunity to directly peel off the protective film 109, although the adhesive layer 3 of the adhesive portion 4 has a stronger adhesive force than the adhesive force of the adhesive layer 110 between the polarizing plate 107 and the protective film 109. However, between the polarizing plate 107 and the protective film 109, in addition to the adhesive force caused by the adhesive layer 110 at the place, the adhesive force caused by the differential pressure generated on both sides of the protective film 109 also functions, so As shown by the imaginary line of 9 (B), the protective film 109 could not be peeled off, and only the peeling tape 1 was peeled off, causing a problem. On the other hand, as shown in FIG. 10(A) and FIG. 10(B), the release tape is attached. When the white M is removed on the right side, the adhesive portion 4 can be covered on the right end edge of the protective film to produce the peeling protective film 109, as shown by the imaginary line in Fig. 10(B). The right end portion of the protective film 109 can be peeled off from the release tape 1 and the entire end of the protective film 109 can be peeled off, and all the protective films 109 can be continuously peeled off.

此外,圖11揭示,相對於玻璃基板101,偏光板107貼附在從正確位置朝剝離膠帶1貼附位置相反側即左側偏離的位置之情形。此外,圖11揭示於貼附剝離膠帶1之際,有取留白M之情形。圖11(A)為相當於圖8(A)之表面圖(正面圖),圖11(B)為相當於圖8(B)之截面圖。圖11(A)的假想線,表示偏光板107的正確貼附位置。 Further, FIG. 11 discloses that the polarizing plate 107 is attached to a position deviated from the correct position toward the side opposite to the attachment position of the release tape 1 from the correct position with respect to the glass substrate 101. In addition, FIG. 11 discloses a case where the white tape M is taken when the release tape 1 is attached. Fig. 11(A) is a surface view (front view) corresponding to Fig. 8(A), and Fig. 11(B) is a cross-sectional view corresponding to Fig. 8(B). The imaginary line of Fig. 11(A) indicates the correct attachment position of the polarizing plate 107.

如圖11(A)、圖11(B)所示,當偏光板107貼附在從正確位置朝左側偏離的位置之情形下,於貼附剝離膠帶1之際,無論在右側有取或未取留白M的情況下,都不會造成喪失剝離保護膜109的契機而引起保護膜109的剝離不良。但,如圖11(A)、圖11(B)所示,當在右側有取留白M的情況下,黏著部4除了因為該留白M而從保護膜109朝右側的伸出量M以外,還會因為偏光板107亦即保護膜109朝左側的位置偏差,導致黏著部4多出從保護膜109朝右側的伸出量α,故黏著部4會超出預先設定好的留白M而朝保護膜109右側伸出。這樣一來,如圖11(B)所示,從保護膜109朝右側伸出的黏著部4,會容易與其正下方露出的玻璃基板101密合 而貼附。而在此狀態下,若進行保護膜109的剝離工程,則黏著部4的黏著劑層3造成的黏著力強反而幫了倒忙,結果無法剝離保護膜109,而是將液晶面板100或液晶模組200本體拉起,導致問題。 As shown in FIG. 11(A) and FIG. 11(B), when the polarizing plate 107 is attached to the position deviated from the correct position to the left side, when the peeling tape 1 is attached, whether or not the right side is taken or not When the white M is left, the peeling of the protective film 109 is not caused, and the peeling failure of the protective film 109 is caused. However, as shown in FIG. 11(A) and FIG. 11(B), in the case where the white M is taken on the right side, the sticking portion 4 has a projection amount M from the protective film 109 toward the right side except for the margin M. In addition, the polarizing plate 107, that is, the position of the protective film 109 toward the left side, causes the adhesive portion 4 to have a larger amount of protrusion α from the protective film 109 toward the right side, so that the adhesive portion 4 exceeds the preset margin M. It protrudes toward the right side of the protective film 109. As a result, as shown in FIG. 11(B), the adhesive portion 4 projecting from the protective film 109 toward the right side is easily adhered to the glass substrate 101 exposed directly below. And attached. On the other hand, when the peeling process of the protective film 109 is performed, the adhesive force of the adhesive layer 3 of the adhesive portion 4 is strong, but the protective film 109 is not peeled off, but the liquid crystal panel 100 or the liquid crystal is removed. The module 200 is pulled up, causing problems.

本發明之目的在於提供一種剝離膠帶及具備其之液晶面板、液晶模組,其解決前述習知剝離膠帶之問題點,能夠將貼附於液晶面板的偏光板之保護膜容易且確實地剝離,同時能實現此一效果而不對液晶面板的生產性等造成影響。 An object of the present invention is to provide a release tape, a liquid crystal panel including the same, and a liquid crystal module, which solve the problem of the conventional release tape, and can easily and reliably peel off the protective film attached to the polarizing plate of the liquid crystal panel. At the same time, this effect can be achieved without affecting the productivity of the liquid crystal panel and the like.

作為用來解決前述問題點之手段,本發明之剝離膠帶,係為一種剝離膠帶,屬於在液晶面板最表面設有偏光板,而在該偏光板表面上貼附之保護膜的剝離膠帶,其構成為:由黏著部與非黏著部所構成,前述黏著部具有前述液晶面板的前述偏光板與前述保護膜之間的黏著力以上的黏著力,且形成於剝離膠帶長邊方向的一方之端 部,前述非黏著部形成於剝離膠帶長邊方向的另一方之端部,該些黏著部與非黏著部係在剝離膠帶的長邊方向鄰接而形成,外形形狀構成為長方形的剝離膠帶,且前述黏著部與前述非黏著部係形成為,在前述黏著部靠非黏著部側的端部,前述非黏著部的一部分呈伸出之形狀。 As a means for solving the above problems, the release tape of the present invention is a release tape, which is a release tape provided with a polarizing plate on the outermost surface of the liquid crystal panel and a protective film attached to the surface of the polarizing plate. The adhesive portion is formed of an adhesive portion and a non-adhesive portion, and the adhesive portion has an adhesive force equal to or higher than an adhesive force between the polarizing plate and the protective film of the liquid crystal panel, and is formed at one end of the longitudinal direction of the release tape. The non-adhesive portion is formed at the other end portion in the longitudinal direction of the release tape, and the adhesive portion and the non-adhesive portion are formed adjacent to each other in the longitudinal direction of the release tape, and the outer shape is formed into a rectangular release tape, and The adhesive portion and the non-adhesive portion are formed such that a part of the non-adhesive portion protrudes from an end portion of the adhesive portion on the non-adhesive portion side.

此外,本發明之剝離膠帶當中,較佳是,在剝離膠帶寬幅方向的至少一方之端部,會保留黏著部靠非黏著部側端部之形狀,而在黏著部靠非黏著部側的端部,非黏著部的一部分會伸出。此外,更佳是,在剝離膠帶寬幅方向的雙方之端部,會保留黏著部靠非黏著部側端部之形狀,而在黏著部靠非黏著部側的端部,非黏著部的一部分會伸出。 Further, in the release tape of the present invention, it is preferable that at least one end portion of the strip width direction of the peeling adhesive retains the shape of the non-adhesive side end portion of the adhesive portion, and the non-adhesive portion side of the adhesive portion At the end, a portion of the non-adhesive portion will extend. Further, it is more preferable that the end portions of both sides of the peeling tape width direction retain the shape of the non-adhesive side end portion of the adhesive portion, and the non-adhesive portion of the adhesive portion at the non-adhesive portion side end portion. Will stretch out.

依照本發明之剝離膠帶,例如將黏著部的外形形狀,從習知的長方形改成形成為具有朝向非黏著部側開口的凹陷部之凹型,將非黏著部的外形形狀,從習知的長方形改成形成為具有朝向黏著部側伸出而與黏著部的凹陷部嵌合的伸出部之凸型,然後在液晶面板的製造工程當中偏光板的貼附工程以降,係在有取留白之狀態下,透過黏著部將剝離膠帶貼附於保護膜,以便包含保護膜端部的至少一部分,且非黏著部會從保護膜伸出,且黏著部靠非黏著部側的端部會從保護膜伸出;藉此,相對於液晶面板的基板,就算偏光板貼附在從正確位置朝剝離膠帶的貼附位置側偏離的位置之情形下,仍會由於黏著部的黏著力比偏光板與保護膜之間的黏著力還強,且於貼附剝離膠帶之 際藉由所取的留白而黏著部會覆蓋保護膜端部的至少一部分,故當使用者剝離保護膜109時,藉由將剝離膠帶的非黏著部朝向規定方向拉扯,便能與剝離膠帶成為一體而剝離保護膜端部的至少一部分,並以該處為開端,能夠連續地將所有保護膜容易且確實地剝離。 According to the release tape of the present invention, for example, the outer shape of the adhesive portion is changed from a conventional rectangular shape into a concave shape having a concave portion opening toward the non-adhesive portion side, and the outer shape of the non-adhesive portion is obtained from a conventional rectangular shape. It is formed into a convex shape having a projecting portion that protrudes toward the side of the adhesive portion and is fitted into the recessed portion of the adhesive portion, and then the attachment process of the polarizing plate is lowered in the manufacturing process of the liquid crystal panel. In a state in which the release tape is attached to the protective film through the adhesive portion so as to include at least a portion of the end portion of the protective film, and the non-adhesive portion protrudes from the protective film, and the end portion of the adhesive portion on the non-adhesive portion side is The protective film is extended; thereby, with respect to the substrate of the liquid crystal panel, even if the polarizing plate is attached to a position deviated from the correct position toward the attachment position side of the release tape, the adhesive force of the adhesive portion is higher than that of the polarizing plate. The adhesion between the protective film and the protective film is strong, and the adhesive tape is attached. The adhesive portion covers at least a portion of the end portion of the protective film by the white space taken, so that when the user peels off the protective film 109, the non-adhesive portion of the release tape is pulled in a predetermined direction, and the peeling tape can be removed. As a whole, at least a part of the end portion of the protective film is peeled off, and at this point, the entire protective film can be easily and reliably peeled off continuously.

此外,反之,相對於基板,就算偏光板貼附在從正確位置朝與剝離膠帶貼附位置相反側偏離的位置之情形下,於貼附剝離膠帶之際,就算如習知般取相同量的留白,也會因為黏著部與非黏著部係形成為在黏著部靠非黏著部側的端部,非黏著部的一部分呈伸出之形狀,故黏著部從保護膜伸出的面積會比習知來得少,即使從保護膜伸出的黏著部與其正下方露出的基板密合貼附,其面積也會變得比習知少。因此,當使用者剝離保護膜時,就算從保護膜伸出的黏著部與基板密合貼附之情形下,藉由將剝離膠帶的非黏著部朝規定方向拉扯,該貼附之小面積的黏著部,仍會從基板被剝離而不致於將液晶面板或液晶模組本體拉起,能夠與剝離膠帶成為一體而剝離保護膜端部的至少一部分,並以該處為開端,能夠連續地將所有保護膜容易且確實地剝離。 Further, on the other hand, with respect to the substrate, even if the polarizing plate is attached to a position deviated from the correct position toward the side opposite to the side where the peeling tape is attached, when the peeling tape is attached, the same amount is taken as is conventionally known. The white space is also formed because the adhesive portion and the non-adhesive portion are formed at the end portion of the adhesive portion on the non-adhesive portion side, and a portion of the non-adhesive portion is extended, so that the area of the adhesive portion protruding from the protective film is higher than that of the adhesive portion. Conventionally, even if the adhesive portion protruding from the protective film is closely attached to the substrate exposed directly below, the area thereof becomes smaller than conventionally. Therefore, when the user peels off the protective film, even if the adhesive portion protruding from the protective film is adhered to the substrate, the small area of the attached tape is pulled by pulling the non-adhesive portion of the release tape in a predetermined direction. The adhesive portion is still peeled off from the substrate without pulling up the liquid crystal panel or the liquid crystal module body, and can be integrated with the release tape to peel off at least a part of the end portion of the protective film, and can be continuously opened at the same position. All protective films are easily and surely peeled off.

又,剝離膠帶的外形形狀與習知無異同為長方形,故不會對於既有的液晶面板製造工程之產距時間(takt time)及作業性等帶來變化,便能夠獲得前述作用效果。 Further, since the outer shape of the release tape is different from the conventional one, it is a rectangular shape. Therefore, the above-described effects can be obtained without changing the takt time and workability of the conventional liquid crystal panel manufacturing process.

以下依據圖面,說明本發明之實施形態。首先,圖1揭示本發明實施形態之剝離膠帶11。圖1(A)為側面圖、圖1(B)為裏面圖(背面圖)。 Embodiments of the present invention will be described below based on the drawings. First, Fig. 1 discloses a release tape 11 according to an embodiment of the present invention. Fig. 1(A) is a side view, and Fig. 1(B) is a rear view (rear view).

在圖1(A)、圖1(B)所示例子中,剝離膠帶11是由:片狀的黏著部14,形成於剝離膠帶11長邊 方向(左右方向)一方的端部即左端部,外形形狀為凹字形;及片狀的非黏著部15,形成於剝離膠帶11長邊方向另一方的端部即右端部,外形形狀為凸字形;所構成。具體而言,係具有由片狀樹脂膜所構成之外形形狀呈長方形的一片基材(膠帶本體)12,以從該基材12長邊方向(左右方向)左端至中途為止之長方形(寛度與膠帶寛度相同,長度比膠帶長還短之長方形)區域作為基準,僅在將該基準的長方形右端部(膠帶內側端部)中央切除四角形而成之凹字形區域的裏面,形成如圖6(A)、圖6(B)、圖6(C)所示比液晶面板100的偏光板107與保護膜109之間的黏著劑層110造成的黏著力還具有更強力黏著力之黏著劑層13,藉此,在剝離膠帶11的左端部會形成片狀的黏著部14,其為基材12與黏著劑層13的二層構造,黏著劑層13在剝離膠帶11的裏面側會露出,且外形形狀為凹字形,在右端部的中央具有朝向右側開口之單一四角形(ㄇ字形)之凹陷部14a。另一方面,以從基材12長邊方向右端至中途為止之長方形(寛度與膠帶寛度相同,長度比膠帶長還短之長方形)區域(從基材12左端至中途為止之長方形區域以外的長方形區域)作為基準,在該基準的長方形左端部(膠帶內側端部)中央,加上和從基材12左端至中途為止之長方形區域的右端部中央切除形狀相當之四角形而成之凸字形區域(凹字形的黏著部14以外之區域)的裏面,並未形成黏著劑層13,藉此,在剝離膠帶11右端部會形成片狀的非黏著部15,其 為僅有基材12的單層構造,基材12在剝離膠帶11的裏面側會露出,且外形形狀為凸字形,在左端部的中央具有朝向左側伸出而與黏著部14的凸陷部14a嵌合之單一四角形(ㄇ字形)之伸出部15a。此外,構成黏著劑層13長邊方向的右側端緣之一條方波狀的線,亦即在剝離膠帶11長邊方向的中途垂直橫跨剝離膠帶11寬幅方向上下側端緣間的一條直線的中央彎曲成朝向右側開口之ㄇ字形的一條線,會成為黏著部14與非黏著部15之間的交界線16,顯現於剝離膠帶11的裏面側。 In the example shown in Figs. 1(A) and 1(B), the release tape 11 is formed of a sheet-like adhesive portion 14 formed on the long side of the release tape 11 The end portion of the direction (left-right direction), that is, the left end portion, has an outer shape of a concave shape, and the sheet-shaped non-adhesive portion 15 is formed at the other end portion of the peeling tape 11 in the longitudinal direction, that is, the right end portion, and has an outer shape of a convex shape. ; constitutes. Specifically, a base material (tape main body) 12 having a rectangular outer shape and a rectangular shape formed of a sheet-like resin film is formed, and a rectangular shape is formed from the left end to the middle of the base material 12 in the longitudinal direction (left-right direction). As a reference, the area of the rectangular right end portion (the inner end portion of the tape) is cut out from the center of the concave shape of the rectangular right end portion (the inner end portion of the tape). (A), FIG. 6(B), FIG. 6(C) shows an adhesive layer which has a stronger adhesive force than the adhesive layer 110 between the polarizing plate 107 of the liquid crystal panel 100 and the protective film 109. 13. Thereby, a sheet-like adhesive portion 14 is formed at the left end portion of the release tape 11, which is a two-layer structure of the base material 12 and the adhesive layer 13, and the adhesive layer 13 is exposed on the back side of the release tape 11. Further, the outer shape is a concave shape, and a concave portion 14a having a single quadrangular shape (ㄇ-shaped) opening toward the right side is provided at the center of the right end portion. On the other hand, a rectangular shape (a rectangle having the same twist and tape length as the tape length and a shorter length than the tape length) from the right end in the longitudinal direction of the substrate 12 to the middle (outside the rectangular region from the left end to the middle of the substrate 12) In the center of the rectangular left end portion (the inner end portion of the tape) of the reference, a square shape formed by cutting a square shape having a shape corresponding to the center of the right end portion of the rectangular region from the left end to the middle of the base material 12 is used as a reference. The adhesive layer 13 is not formed on the inside of the region (the region other than the concave portion 14 of the concave shape), whereby a sheet-shaped non-adhesive portion 15 is formed at the right end portion of the release tape 11 In the single-layer structure of only the substrate 12, the substrate 12 is exposed on the back side of the release tape 11, and has an outer shape of a chevron shape, and has a convex portion that protrudes toward the left side and the adhesive portion 14 at the center of the left end portion. 14a is a single quadrangular (ㄇ-shaped) projecting portion 15a. Further, a square wave-shaped line constituting the right end edge of the adhesive layer 13 in the longitudinal direction, that is, a line vertically extending across the upper and lower edges of the peeling tape 11 in the longitudinal direction of the peeling tape 11 in the longitudinal direction The center is bent so that a line of a U-shape opening toward the right side becomes a boundary line 16 between the adhesive portion 14 and the non-adhesive portion 15, and appears on the back side of the release tape 11.

像這樣,剝離膠帶11是由黏著部14與非黏著部15所構成,黏著部14具有圖6(A)、圖6(B)、圖6(C)所示液晶面板100的偏光板107與保護膜109之間的黏著力以上的黏著力,且形成於剝離膠帶11長邊方向的一方之端部,非黏著部15形成於剝離膠帶11長邊方向的另一方之端部,該些黏著部14與非黏著部15係在剝離膠帶11的長邊方向鄰接而形成,外形形狀構成為長方形的剝離膠帶11。又,黏著部14與非黏著部15係形成為,在黏著部14靠非黏著部15側(膠帶內側)之端部,非黏著部15的一部分呈伸出之形狀。此外,在剝離膠帶11寬幅方向的至少一方之端部,會保留黏著部14靠非黏著部15側端部之形狀,而在黏著部14靠非黏著部15側的端部,非黏著部15的一部分會伸出。又,剝離膠帶11寬幅方向的兩方之端部,會保留黏著部14靠非黏著部15側端部之形狀,而在黏著部14靠非黏著部15側的 端部,非黏著部15的一部分會伸出。再者,黏著部14的外形形狀係形成為凹型而具有朝向非黏著部15側開口之凹陷部14a,非黏著部15的外形形狀係形成為凸型而具有朝向黏著部14側伸出而與黏著部14的凹陷部14a嵌合之伸出部15a。 As described above, the release tape 11 is composed of the adhesive portion 14 and the non-adhesive portion 15, and the adhesive portion 14 has the polarizing plate 107 of the liquid crystal panel 100 shown in Figs. 6(A), 6(B), and 6(C). An adhesive force equal to or higher than the adhesive force between the protective films 109 is formed at one end portion of the peeling tape 11 in the longitudinal direction, and the non-adhesive portion 15 is formed at the other end portion of the peeling tape 11 in the longitudinal direction, and the adhesive portions are adhered. The portion 14 and the non-adhesive portion 15 are formed adjacent to each other in the longitudinal direction of the release tape 11, and the outer shape is formed into a rectangular release tape 11. Further, the adhesive portion 14 and the non-adhesive portion 15 are formed such that a part of the non-adhesive portion 15 protrudes from the end portion of the adhesive portion 14 on the non-adhesive portion 15 side (inner tape side). Further, at least one end portion of the peeling tape 11 in the width direction retains the shape of the end portion of the adhesive portion 14 on the non-adhesive portion 15 side, and the non-adhesive portion at the end portion of the adhesive portion 14 on the non-adhesive portion 15 side. Part of 15 will stick out. Further, both end portions of the peeling tape 11 in the width direction retain the shape of the end portion of the adhesive portion 14 on the side of the non-adhesive portion 15, and the adhesive portion 14 is on the side of the non-adhesive portion 15 At the end, a portion of the non-adhesive portion 15 will protrude. Further, the outer shape of the adhesive portion 14 is formed in a concave shape and has a recessed portion 14a that opens toward the non-adhesive portion 15 side. The outer shape of the non-adhesive portion 15 is formed into a convex shape and protrudes toward the adhesive portion 14 side. The protruding portion 15a of the concave portion 14a of the adhesive portion 14 is fitted.

具備該剝離膠帶11之液晶面板及液晶模組,係為如圖6(A)、圖6(B)、圖6(C)所示之液晶面板100及液晶模組200,具有如前述般的構成。又,剝離膠帶11屬於在液晶面板100最表面上設置偏光板107,而在該偏光板107的表面上貼附之保護膜109的剝離膠帶11,具有如前述般的構成。 The liquid crystal panel and the liquid crystal module including the release tape 11 are the liquid crystal panel 100 and the liquid crystal module 200 as shown in FIGS. 6(A), 6(B), and 6(C), and have the above-described Composition. Further, the release tape 11 belongs to a release tape 11 in which a polarizing plate 107 is provided on the outermost surface of the liquid crystal panel 100, and the protective film 109 attached to the surface of the polarizing plate 107 has the above-described configuration.

接下來,圖2揭示將該剝離膠帶11貼附於保護膜109狀態下之液晶面板100。圖2(A)為表面圖(正面圖)、圖2(B)為截面圖。此外,圖2(A)、圖2(B)中,比表側的玻璃基板101還裏側之構造是以透明化狀態表示。又,圖2(B)中,貼附有剝離膠帶11的部分是以放大狀態表示。 Next, FIG. 2 discloses the liquid crystal panel 100 in which the release tape 11 is attached to the protective film 109. 2(A) is a surface view (front view) and FIG. 2(B) is a cross-sectional view. In addition, in FIGS. 2(A) and 2(B), the structure on the back side of the glass substrate 101 on the front side is shown in a transparent state. Further, in Fig. 2(B), the portion to which the release tape 11 is attached is shown in an enlarged state.

剝離膠帶11在考量經濟性下係比保護膜109還充分小(窄而短),例如隔著黏著部14貼附於保護膜109一方之端部即右端部,使得黏著部14覆蓋在保護膜109長邊方向(左右方向)一方之端緣即右側端緣,且非黏著部15從保護膜109朝右側伸出。此外,在貼附該剝離膠帶11之際,並非將黏著部14與非黏著部15之間的交界線16兩端的直線部分切齊保護膜109的右側端緣, 而是以稍微取一留白M的狀態來貼附,使得黏著部14的右側端部從保護膜109的右側端緣朝更右側伸出。而當使用者例如以機械方式剝離保護膜109時,將剝離膠帶11的非黏著部15如圖2(B)箭頭所示朝左斜上方(相對於偏光板107呈150度之角度)拉扯,藉此,相較於偏光板107與保護膜109之間的黏著劑層110造成的黏著力,黏著部14的黏著劑層13造成的黏著力較強,且在保護膜109的右側端緣覆蓋著黏著部14,故如圖2(B)假想線所示,能夠與剝離膠帶11成為一體而剝離保護膜109的右端部,並以該處為開端,能夠連續地剝離所有保護膜109。 The release tape 11 is sufficiently smaller (narrower and shorter) than the protective film 109 in consideration of economy, for example, attached to the end portion of the protective film 109, that is, the right end portion via the adhesive portion 14, so that the adhesive portion 14 is covered with the protective film. The end edge of one of the longitudinal direction (left-right direction) of 109 is the right end edge, and the non-adhesive portion 15 protrudes from the protective film 109 toward the right side. Further, when the release tape 11 is attached, the straight portion of the both ends of the boundary line 16 between the adhesive portion 14 and the non-adhesive portion 15 is not cut to the right end edge of the protective film 109. Instead, it is attached in a state in which a white M is slightly taken, so that the right end portion of the adhesive portion 14 protrudes from the right end edge of the protective film 109 toward the right side. When the user peels the protective film 109 mechanically, for example, the non-adhesive portion 15 of the release tape 11 is pulled obliquely upward (at an angle of 150 degrees with respect to the polarizing plate 107) as indicated by an arrow in FIG. 2(B). Thereby, the adhesive force of the adhesive layer 13 of the adhesive portion 14 is stronger than that of the adhesive layer 110 between the polarizing plate 107 and the protective film 109, and is covered on the right end edge of the protective film 109. As shown in the imaginary line of FIG. 2(B), the adhesive portion 14 can be integrally formed with the release tape 11, and the right end portion of the protective film 109 can be peeled off, and at this point, the entire protective film 109 can be continuously peeled off.

圖2(A)、圖2(B)揭示相對於玻璃基板101而言貼附於正確位置的偏光板107。 2(A) and 2(B) disclose a polarizing plate 107 attached to the correct position with respect to the glass substrate 101.

接下來,圖3揭示,相對於玻璃基板101,偏光板107貼附在從正確位置朝剝離膠帶11貼附位置側即右側偏離的位置之情形。圖3(A)為相當於圖2(A)之表面圖(正面圖),圖3(B)為相當於圖2(B)之截面圖。圖3(A)的假想線,表示偏光板107的正確貼附位置。 Next, FIG. 3 discloses that the polarizing plate 107 is attached to a position deviated from the correct position toward the attachment position side, that is, the right side with respect to the glass substrate 101. Fig. 3(A) is a surface view (front view) corresponding to Fig. 2(A), and Fig. 3(B) is a cross-sectional view corresponding to Fig. 2(B). The imaginary line of Fig. 3(A) indicates the correct attachment position of the polarizing plate 107.

如圖3(A)、圖3(B)所示,相對於玻璃基板101,就算偏光板107貼附在從正確位置朝與剝離膠帶11貼附位置相反側偏離的位置之情形下,於貼附剝離膠帶11之際,由於在右側有取留白M,故能夠將黏著部14覆蓋於保護膜109的右側端緣,製造剝離保護膜109的契 機,而如圖3(B)假想線所示,會與剝離膠帶11成為一體而能夠剝離保護膜109的右端部,並以該處為開端,能夠連續地剝離所有保護膜109。 As shown in FIG. 3(A) and FIG. 3(B), with respect to the glass substrate 101, even if the polarizing plate 107 is attached to a position deviated from the correct position toward the side opposite to the attachment position of the release tape 11, When the peeling tape 11 is attached, since the white M is removed on the right side, the adhesive portion 14 can be covered on the right end edge of the protective film 109, and the peeling protective film 109 can be manufactured. As shown in the imaginary line of FIG. 3(B), the right end portion of the protective film 109 can be peeled off from the peeling tape 11, and the protective film 109 can be continuously peeled off at the beginning.

接下來,圖4揭示,相對於玻璃基板101,偏光板107貼附在從正確位置朝剝離膠帶11貼附位置相反側即左側偏離的位置之情形。圖4(A)為相當於圖2(A)之表面圖(正面圖),圖4(B)為相當於圖2(B)之截面圖。圖4(A)的假想線,表示偏光板107的正確貼附位置。 Next, FIG. 4 discloses that, with respect to the glass substrate 101, the polarizing plate 107 is attached to a position deviated from the correct position toward the side opposite to the attachment position of the release tape 11 to the left side. 4(A) is a surface view (front view) corresponding to FIG. 2(A), and FIG. 4(B) is a cross-sectional view corresponding to FIG. 2(B). The imaginary line of Fig. 4(A) indicates the correct attachment position of the polarizing plate 107.

如圖4(A)、圖4(B)所示,當偏光板107貼附在從正確位置朝左側偏離的位置之情形下,於貼附剝離膠帶11之際,黏著部14除了因為右側取的留白M而從保護膜109朝右側的伸出量M以外,還會因為偏光板107亦即保護膜109朝左側的位置偏差,導致黏著部14多出從保護膜109朝右側的伸出量α,故黏著部14會超出預先設定好的留白M而朝保護膜109右側伸出。但,將圖4(A)、圖4(B)與圖11(A)、圖11(B)比較可知,剝離膠帶11當中,於其貼附之際,就算如習知般取相同量的留白M,也會因為黏著部14與非黏著部15係形成為在黏著部14靠非黏著部15側的端部,非黏著部15的一部分呈伸出之形狀,故黏著部14從保護膜109伸出的面積會比習知來得少,即使從保護膜109伸出的黏著部14與其正下方露出的玻璃基板101密合貼附,其面積也會變得比習知少。因此,當使用者剝離保護膜109時, 如圖4(B)實線所示,就算從保護膜109伸出的黏著部14與玻璃基板101密合貼附之情形下,藉由將剝離膠帶11的非黏著部朝規定方向拉扯,該貼附之小面積的黏著部14,仍如圖4(B)假想線所示,會從玻璃基板101被剝離而不致於將液晶面板100或液晶模組200本體拉起,能夠剝離保護膜109的右端部,並以該處為開端,能夠連續地將所有保護膜109容易且確實地剝離。 As shown in FIG. 4(A) and FIG. 4(B), when the polarizing plate 107 is attached to the position deviated from the correct position to the left side, the adhesive portion 14 is taken in addition to the right side when the peeling tape 11 is attached. In addition to the amount of protrusion M from the protective film 109 toward the right side, the position of the polarizing plate 107, that is, the position of the protective film 109 toward the left side, may cause the adhesive portion 14 to protrude from the protective film 109 toward the right side. The amount α is such that the adhesive portion 14 protrudes beyond the predetermined margin M to the right side of the protective film 109. 4(A) and 4(B), as compared with FIG. 11(A) and FIG. 11(B), it can be seen that, in the peeling tape 11, when it is attached, the same amount is taken as is conventionally known. The white portion M is also formed such that the adhesive portion 14 and the non-adhesive portion 15 are formed at the end portion of the adhesive portion 14 on the non-adhesive portion 15 side, and a part of the non-adhesive portion 15 is extended, so that the adhesive portion 14 is protected. The area in which the film 109 protrudes is less than conventionally known, and even if the adhesive portion 14 extending from the protective film 109 is closely adhered to the glass substrate 101 exposed directly below, the area thereof becomes smaller than conventional. Therefore, when the user peels off the protective film 109, As shown by the solid line in FIG. 4(B), even when the adhesive portion 14 extending from the protective film 109 is adhered to the glass substrate 101, the non-adhesive portion of the release tape 11 is pulled in a predetermined direction. The small-sized adhesive portion 14 attached is peeled off from the glass substrate 101 as shown in the imaginary line of FIG. 4(B) without pulling up the liquid crystal panel 100 or the liquid crystal module 200, and the protective film 109 can be peeled off. The right end portion, starting from this point, can continuously and reliably peel off all of the protective films 109.

又,將圖2(A)與圖8(A)比較可知,剝離膠帶11的外形形狀與習知無異同為長方形,故不會對於既有的液晶面板製造工程之產距時間(takt time)及作業性等帶來變化,便能夠獲得前述作用效果。 2(A) and FIG. 8(A), it can be seen that the outer shape of the release tape 11 is different from the conventional one, so that it does not have a takt time for the existing liquid crystal panel manufacturing process. When the workability and the like are changed, the aforementioned effects can be obtained.

是故,依照剝離膠帶11,能夠將貼附於液晶面板100的偏光板107之保護膜109容易且確實地剝離,同時能實現此一效果而不對液晶面板100的生產性等造成影響。 Therefore, according to the release tape 11, the protective film 109 attached to the polarizing plate 107 of the liquid crystal panel 100 can be easily and reliably peeled off, and this effect can be achieved without affecting the productivity and the like of the liquid crystal panel 100.
