Description

顯示面板之製造方法 Manufacturing method of display panel

本發明係關於平面形狀為矩形以外的異形形狀之顯示面板之製造方法。 The present invention relates to a method for manufacturing a display panel whose planar shape is a special shape other than a rectangle.

例如,液晶顯示面板係具有下述構造:在彼此以相對方向之方式所配置的元件基板與對向基板之間配置液晶層,並且在元件基板與對向基板的外表面貼合有偏光膜(偏光板)等光學膜。 For example, a liquid crystal display panel has a structure in which a liquid crystal layer is arranged between an element substrate and a counter substrate that are arranged in opposite directions to each other, and a polarizing film is attached to the outer surfaces of the element substrate and the counter substrate ( Polarizing plate) and other optical films.

在製造此種液晶顯示面板時,係製作排列複數個成為液晶顯示面板之部分(單元)所形成之面板製作用基板之後,由該面板製作用基板切出各單元,藉此進行一次性地進行製造複數個液晶顯示面板(例如,參照專利文獻1、2)。 When manufacturing this type of liquid crystal display panel, a panel production substrate formed by arranging a plurality of parts (units) that become the liquid crystal display panel is produced, and each unit is cut out from the panel production substrate, thereby performing a one-time operation A plurality of liquid crystal display panels are manufactured (for example, refer to Patent Documents 1 and 2).

近來,作為使用於智慧型手錶和車載儀表等之顯示面板,對於與傳統之平面形狀為矩形(長方形)者(意指矩形顯示面板)不同、且平面形狀為矩形以外者(意指異形顯示面板)的需求正在提升。 Recently, as a display panel used in smart watches and in-vehicle instruments, it is different from the traditional rectangular (rectangular) shape (meaning rectangular display panel), and the flat shape is other than rectangular (meaning special-shaped display panel). ) Demand is increasing.

然而,當為傳統的矩形顯示面板,貼合偏光膜時只要以面板的四角(角部)為基準進行對位即可,較容易進行偏光膜的對位。相對於此,為異形顯示面板時,貼合偏光膜時的對位係較為矩形顯示面板時更為困難。尤其,為圓形顯示面板時,會無法得知相對於該顯示面板之偏光膜的偏光軸傾斜,故貼合偏光膜時的對位會變得非常困難。 However, in the case of a conventional rectangular display panel, the polarizing film only needs to be aligned with the four corners (corners) of the panel as a reference when attaching the polarizing film, and the polarizing film is easier to align. In contrast, when it is a special-shaped display panel, it is more difficult to align the polarizing film when it is a rectangular display panel. In particular, in the case of a circular display panel, the tilt of the polarization axis with respect to the polarizing film of the display panel cannot be known, so the alignment when the polarizing film is attached becomes very difficult.

再者,製造矩形顯示面板時,係將上述面板製作用基板裁切成格子狀,藉此可一次性地切出矩形顯示面板。相對於此,製造異形顯示面板時,需沿著異形顯示面板的輪廓從面板製作用基板將單元一個個地切出。此時,從面板製作用基板切出單元時的對位係較製造矩形顯示面板時更為困難。 Furthermore, when manufacturing a rectangular display panel, the above-mentioned panel manufacturing substrate is cut into a grid shape, whereby the rectangular display panel can be cut out at once. On the other hand, when manufacturing a special-shaped display panel, it is necessary to cut out the cells one by one from the panel production substrate along the outline of the special-shaped display panel. At this time, the alignment system when cutting out the unit from the substrate for panel production is more difficult than when manufacturing a rectangular display panel.

Specifically, it is preferable that among the four corners of the facing mother substrate 2A, the first alignment mark AM1 is provided at at least two corners along the same end side.

於對向用母基板2A貼合偏光膜5A時,係一邊參照第一對位記號AM1一邊進行偏光膜5A相對於對向用母基板2A之對位。藉此,可在對向用母基板2A的四 角與偏光膜5A的四角互為一致之狀態,正確且容易地將偏光膜5A貼合於對向用母基板2A。 When bonding the polarizing film 5A to the facing mother substrate 2A, the polarizing film 5A is aligned with respect to the facing mother substrate 2A while referring to the first alignment mark AM1. Thereby, the four The corners and the four corners of the polarizing film 5A coincide with each other, and the polarizing film 5A is accurately and easily bonded to the opposing mother substrate 2A.

而且,元件用母基板3A中,雖於圖示中有所省略,但與對向用母基板2A同樣地設有表示偏光膜5B貼合位置之第一對位記號AM1。並且,於該元件用母基板3A貼合偏光膜5B時,係一邊參照第一對位記號AM1一邊進行偏光膜5B相對於元件用母基板3A之對位。藉此,可在元件用母基板3A的四角與偏光膜5B的四角互為一致之狀態,正確且容易地將偏光膜5B貼合於元件用母基板3A。 In addition, in the element mother substrate 3A, although omitted from the illustration, the first alignment mark AM1 indicating the bonding position of the polarizing film 5B is provided in the same way as the facing mother substrate 2A. When the polarizing film 5B is bonded to the element mother substrate 3A, the polarizing film 5B is aligned with respect to the element mother substrate 3A while referring to the first alignment mark AM1. Thereby, the four corners of the element mother substrate 3A and the four corners of the polarizing film 5B can be aligned with each other, and the polarizing film 5B can be accurately and easily bonded to the element mother substrate 3A.

接著,如第4圖(a)、(b)所示,將貼合於對向用母基板2A的外表面之偏光膜5A沿著成為上述對向基板2之各部分的輪廓裁切為圓形狀。 Next, as shown in Figure 4 (a) and (b), the polarizing film 5A attached to the outer surface of the opposed mother substrate 2A is cut into a circle along the contour of each part that becomes the opposed substrate 2 shape.

裁切偏光膜5A時,使用雷射光(例如,二氧化碳氣體雷射,波長9.4μm)L,該雷射光於掃描同時將偏光膜5A沿著各偏光膜5a的輪廓進行裁切。此時,雷射光造成的裁切線較佳為位於僅較成為對向基板2之部分的輪廓略為內側之位置。藉此,沿著成為對向基板2之部分的輪廓裁切後述對向用母基板2A時,可防止刀具接觸偏光膜5a。 When cutting the polarizing film 5A, laser light (for example, a carbon dioxide gas laser, wavelength 9.4 μm) L is used, and the laser light is scanned while cutting the polarizing film 5A along the contour of each polarizing film 5a. At this time, the cutting line caused by the laser light is preferably located at a position slightly inner than the contour of the portion that becomes the counter substrate 2. This prevents the cutter from contacting the polarizing film 5a when cutting the facing mother substrate 2A along the contour of the portion that becomes the counter substrate 2.

而且,藉由雷射光裁切偏光膜5A時,較佳為從不與形成於各單元1A之成為元件基板3之部分(具體而言為配線形成部3b)之配線部6重疊的位置起開始裁切。因為裁切的開始位置與裁切的結束位置重疊,故從避開配線部6之位置起開始藉由雷射光進行裁切,藉此可防 止雷射光造成的配線部6之損傷等。 Moreover, when cutting the polarizing film 5A by laser light, it is preferable to start from a position that does not overlap with the wiring portion 6 formed in each unit 1A that becomes the element substrate 3 (specifically, wiring forming portion 3b) Cut. Since the cutting start position overlaps with the cutting end position, the laser light is used for cutting from the position avoiding the wiring part 6, thereby preventing Prevent damage to the wiring part 6 caused by laser light.

而且,裁切偏光膜5A時,較佳為各偏光膜5a的輪廓之中,至少從角部開始裁切。藉此,可沿著輪廓將各偏光膜5a完整地切出。但是,如本實施形態,各偏光膜5a的輪廓為圓形時,其輪廓不存在角部,故無需特意規定裁切的開始位置。 Moreover, when cutting the polarizing film 5A, it is preferable to start cutting at least from the corner of the outline of each polarizing film 5a. Thereby, each polarizing film 5a can be completely cut out along the outline. However, as in the present embodiment, when the outline of each polarizing film 5a is circular, the outline does not have corners, so there is no need to specify the starting position of the cutting.

又,本實施形態中,係例示使用雷射光裁切偏光膜5A之情形,惟亦可使用雷射光以外者,例如使用刀具進行偏光膜5A的裁切。 In addition, in this embodiment, the case where laser light is used to cut the polarizing film 5A is exemplified, but other than laser light may be used, for example, a cutter may be used to cut the polarizing film 5A.

然而,如第10圖所示,對向用母基板2A係設有表示各單元1A的位置之第二對位記號AM2。第二對位記號AM2,例如只要在各單元1A的周圍至少設置兩個(本實施形態為兩個)即可。具體而言,較佳為在各單元1A的附近於一定間隔至少設有兩個。 However, as shown in Fig. 10, the facing mother substrate 2A is provided with a second alignment mark AM2 indicating the position of each unit 1A. For example, at least two second alignment marks AM2 (two in this embodiment) may be provided around each unit 1A. Specifically, it is preferable to provide at least two at a certain interval in the vicinity of each unit 1A.

本實施形態中,係一邊參照上述第一對位記號AM1與第二對位記號AM2,一邊對各單元1A的成為對向基板2之部分進行對位。具體而言,係在識別第一對位記號AM1的位置之後,藉由第二對位記號AM2由複數個單元1A之中識別成為裁切對象之單元1A的位置。藉此,可對成為裁切對象之單元1A以良好精度進行雷射光的對位。 In this embodiment, while referring to the above-mentioned first alignment mark AM1 and second alignment mark AM2, the portion of each unit 1A that becomes the counter substrate 2 is aligned. Specifically, after identifying the position of the first alignment mark AM1, the second alignment mark AM2 is used to identify the position of the unit 1A to be cut from among the plurality of units 1A. Thereby, the laser beam can be aligned with good accuracy for the unit 1A to be cut.

而且,本實施形態中,亦可參照對應於位在成為裁切對象之單元1A的周圍之複數個單元1A之第二對位記號AM2而進行。此時,係在由複數個單元1A之中 識別成為裁切對象之單元1A的位置之前,識別位於其周圍之複數個單元1A的位置,藉此可以更良好的精度對成為裁切對象之單元1A進行雷射光的對位。 In addition, in this embodiment, it is also possible to refer to the second alignment mark AM2 corresponding to a plurality of cells 1A located around the cell 1A to be cut. At this time, it is in the multiple units 1A Before recognizing the position of the unit 1A to be cut, the positions of a plurality of units 1A located around it are recognized, so that the laser light alignment of the unit 1A to be cut can be performed with better accuracy.

接著,如第5圖(a)、(b)所示,將偏光膜5A的經裁切的各部分之內側(偏光膜5a)保留,並將偏光膜5A的多餘部分從對向用母基板2A的表面上剝離去除。對於偏光膜5A的多餘部分,較佳為沿著偏光膜5A的對角方向進行剝離。藉此,可從對向用母基板2A的表面上將偏光膜5A的多餘部分完整地剝去。 Next, as shown in Figure 5 (a) and (b), the inner side (polarizing film 5a) of the cut parts of the polarizing film 5A is left, and the excess part of the polarizing film 5A is removed from the opposing mother substrate 2A peeled off the surface. It is preferable to peel off the extra part of the polarizing film 5A along the diagonal direction of the polarizing film 5A. Thereby, the excess part of the polarizing film 5A can be completely peeled off from the surface of the mother substrate 2A for facing.

接著,如第6圖(a)、(b)所示,將貼合於元件用母基板3A的外表面之偏光膜5B沿著成為上述元件基板3(具體而言為元件形成部3a)之各部分的輪廓裁切成圓形狀。 Next, as shown in Figs. 6(a) and (b), the polarizing film 5B bonded to the outer surface of the element mother substrate 3A is formed along the element substrate 3 (specifically, the element forming portion 3a). The outline of each part is cut into a circular shape.

裁切偏光膜5B時,使用雷射光(例如,二氧化碳氣體雷射,波長9.4μm)L,該雷射光於掃描同時將偏光膜5B沿著各偏光膜5b的輪廓進行裁切。此時,雷射光造成的裁切線較佳為位於僅較成為元件形成部3a之部分的輪廓略為內側之位置。藉此,沿著成為元件基板3(元件形成部3a)之部分的輪廓裁切後述元件用母基板3A時,可防止刀具接觸偏光膜5b。 When cutting the polarizing film 5B, laser light (for example, a carbon dioxide gas laser, wavelength 9.4 μm) L is used, and the laser light is scanned while cutting the polarizing film 5B along the contour of each polarizing film 5b. At this time, the cutting line caused by the laser light is preferably located only slightly inward of the contour of the part that becomes the element forming portion 3a. This prevents the cutter from contacting the polarizing film 5b when cutting the element mother substrate 3A described later along the contour of the part that becomes the element substrate 3 (element forming portion 3a).

而且,藉由雷射光裁切偏光膜5B時,較佳為從不與形成於各單元1A的成為元件基板3之部分(具體而言為配線形成部3b)之配線部6重疊的位置起開始裁切。因裁切的開始位置與裁切的結束位置重疊,故藉由以 雷射光從避開配線部6之位置起開始進行裁切,可防止雷射光造成的配線部6之損傷等。 Moreover, when cutting the polarizing film 5B by laser light, it is preferable to start from a position that does not overlap the wiring portion 6 formed in each unit 1A that becomes the element substrate 3 (specifically, the wiring forming portion 3b) Cut. Since the start position of cutting overlaps with the end position of cutting, by using The laser light starts cutting from the position avoiding the wiring part 6, which can prevent damage to the wiring part 6 caused by the laser light.

而且,裁切偏光膜5B時,較佳為各偏光膜5b的輪廓之中,至少從角部開始裁切。藉此,可沿著輪廓完整地切出各偏光膜5b。但是,如本實施形態般,各偏光膜5b的輪廓為圓形時,輪廓不存在角部,故無需特意規定裁切的開始位置。 Moreover, when cutting the polarizing film 5B, it is preferable to start cutting at least from the corner|angular part of the outline of each polarizing film 5b. Thereby, each polarizing film 5b can be completely cut out along the outline. However, as in the present embodiment, when the outline of each polarizing film 5b is circular, the outline does not have corners, so there is no need to specify the starting position of the cutting.

又,本實施形態中,係例示使用雷射光裁切偏光膜5B之情形,惟亦可使用雷射光以外者,例如使用刀具進行偏光膜5B的裁切。 In addition, in the present embodiment, a case where laser light is used to cut the polarizing film 5B is exemplified. However, other than laser light may be used, for example, a cutter may be used to cut the polarizing film 5B.

而且,裁切偏光膜5B時對於各單元1A的成為元件基板3(元件形成部3a)之部分的對位,係與上述裁切偏光膜5A時相同。亦即,本實施形態中,係一邊參照第一對位記號AM1與第二對位記號AM2,一邊對各單元1A的成為元件基板3之部分進行對位。藉此,可對成為裁切對象之單元1A以良好精度進行雷射光的對位。 In addition, when the polarizing film 5B is cut, the alignment of the portion of each unit 1A that becomes the element substrate 3 (element forming portion 3a) is the same as that when the polarizing film 5A is cut. That is, in the present embodiment, while referring to the first alignment mark AM1 and the second alignment mark AM2, the portion of each unit 1A that becomes the element substrate 3 is aligned. Thereby, the laser beam can be aligned with good accuracy for the unit 1A to be cut.

接著,如第7圖(a)、(b)所示,將偏光膜5B之經裁切的各部分之內側(偏光膜5b)保留、並將偏光膜5B的多餘部分從元件用母基板3A的表面上剝離去除。對於偏光膜5B的多餘部分,較佳為沿著偏光膜5B的對角方向進行剝離。藉此,可從元件用母基板3A的表面上將偏光膜5B的多餘部分完整地剝起。 Next, as shown in Figs. 7 (a) and (b), the inner side (polarizing film 5b) of the cut parts of the polarizing film 5B is left, and the excess part of the polarizing film 5B is removed from the element mother substrate 3A Peel off the surface to remove. It is preferable to peel off the excess part of the polarizing film 5B along the diagonal direction of the polarizing film 5B. Thereby, the excess part of the polarizing film 5B can be completely peeled off from the surface of the mother substrate 3A for elements.

接著,如第8圖(a)、(b)所示,將對向用母基板2A沿著成為上述對向基板2之各部分的輪廓裁切為 圓形狀。裁切對向用母基板2A時,可採用使用刀具之劃線裁切加工。對於劃線裁切加工,並無特別限制,只要採用可將對向用母基板2A沿著成為各對向基板2之部分的輪廓進行裁切之方法即可。 Next, as shown in Fig. 8 (a) and (b), the opposing mother substrate 2A is cut along the contour of each part that becomes the opposing substrate 2 as Round shape. When cutting the opposing mother substrate 2A, scribing and cutting using a cutter can be used. There is no particular limitation on the scribing and cutting process, as long as a method can be used that can cut the opposing mother substrate 2A along the contour of the portion of each opposing substrate 2.

而且,對於裁切對向用母基板2A時之各單元1A的成為對向基板2的部分之對位,係與上述裁切偏光膜5A時相同。亦即,本實施形態中,係一邊參照第一對位記號AM1與第二對位記號AM2,一邊對各單元1A的成為對向基板2之部分進行對位。藉此,可以良好精度從對向用母基板2A切出各單元1A的對向基板2。 In addition, the alignment of the portion of each unit 1A that becomes the counter substrate 2 when cutting the counter mother substrate 2A is the same as when cutting the polarizing film 5A described above. That is, in the present embodiment, while referring to the first alignment mark AM1 and the second alignment mark AM2, the portion of each unit 1A that becomes the counter substrate 2 is aligned. Thereby, the counter substrate 2 of each unit 1A can be cut out from the counter mother substrate 2A with good accuracy.

接著,如第9圖(a)、(b)所示,將元件用母基板3A沿著成為上述元件基板3之各部分的輪廓裁切為圓形狀。裁切元件用母基板3A時,可採用使用刀具之劃線裁切加工。對於劃線裁切加工並無特別限制,只要採用可將元件用母基板3A沿著成為各元件基板3之部分的輪廓進行裁切之方法即可。 Next, as shown in Figs. 9(a) and (b), the element mother substrate 3A is cut into a circular shape along the contour of each part that becomes the element substrate 3 described above. When cutting the mother substrate 3A for the component, a scribing cutting process using a cutter can be used. There is no particular limitation on the scribing and cutting process, as long as a method can be used that can cut the component mother substrate 3A along the contour of the part forming each component substrate 3.

而且,對於裁切元件用母基板3A時之各單元1A的成為元件基板3的部分之對位,係與上述裁切偏光膜5A時相同。亦即,本實施形態中,係一邊參照第一對位記號AM1與第二對位記號AM2,一邊對各單元1A的成為元件基板3之部分進行對位。藉此,可以良好精度從元件用母基板3A切出各單元1A的元件基板3。 In addition, the alignment of the part of each unit 1A that becomes the element substrate 3 when the element mother substrate 3A is cut is the same as when the above-mentioned polarizing film 5A is cut. That is, in the present embodiment, while referring to the first alignment mark AM1 and the second alignment mark AM2, the portion of each unit 1A that becomes the element substrate 3 is aligned. Thereby, the element substrate 3 of each unit 1A can be cut out from the element mother substrate 3A with good accuracy.

經由以上所述步驟,可從面板製作用基板10切出各單元1A,並可一次性地製造複數個上述液晶顯 示面板1。 Through the above-mentioned steps, each unit 1A can be cut out from the panel production substrate 10, and a plurality of the above-mentioned liquid crystal displays can be manufactured at once. Display panel 1.

如上所述,與製造矩形顯示面板時相比,製造如上述液晶顯示面板1之異形顯示面板時,從面板製作用基板10切出單元1A時之對位、於對向基板2及元件基板3貼合偏光膜5a,5b時之對位會變得非常困難。 As described above, compared with the manufacturing of rectangular display panels, when manufacturing a special-shaped display panel such as the above-mentioned liquid crystal display panel 1, the alignment when the unit 1A is cut out from the panel manufacturing substrate 10 is placed on the counter substrate 2 and the element substrate 3. It becomes very difficult to align the polarizing films 5a and 5b.

相對於此,本實施形態中,係於矩形狀的對向用母基板2A及元件用母基板3A貼合矩形狀的偏光膜5A,5B,藉此,可於該等對向用母基板2A及元件用母基板3A正確且容易地貼合偏光膜5A,5B。之後,因為是從面板製作用基板10切出各單元1A,故可對液晶顯示面板1以高精度保持偏光膜5a,5b之偏光軸傾斜。 In contrast, in this embodiment, rectangular polarizing films 5A, 5B are bonded to the rectangular opposing mother substrate 2A and the element mother substrate 3A, whereby the opposing mother substrate 2A can be attached to the polarizing films 5A and 5B. And the element mother substrate 3A is accurately and easily bonded to the polarizing films 5A and 5B. After that, since each cell 1A is cut out from the panel production substrate 10, the tilt of the polarization axis of the polarizing films 5a, 5b can be maintained for the liquid crystal display panel 1 with high accuracy.

而且,本實施形態中,係從對向用母基板2A及元件用母基板3A將各個互為相異形狀的對向基板2及元件基板3分別地切出,藉此可以良好效率製造如上述液晶顯示面板1之異形顯示面板。 Furthermore, in this embodiment, the opposed substrate 2 and the element substrate 3 each having a different shape from each other are cut out from the opposed mother substrate 2A and the element mother substrate 3A, so that it can be manufactured efficiently as described above. The special-shaped display panel of the liquid crystal display panel 1.

而且,本實施形態中,係一邊參照第一對位記號AM1與第二對位記號AM2一邊對成為各單元1A之部分進行對位,藉此可提高於對向基板2及元件基板3貼合偏光膜5a,5b時之位置精度、與從對向用母基板2A及元件用母基板3A切出對向基板2及元件基板3時之位置精度。 In addition, in this embodiment, the part that becomes each unit 1A is aligned while referring to the first alignment mark AM1 and the second alignment mark AM2, thereby improving the bonding to the counter substrate 2 and the element substrate 3 The position accuracy of the polarizing films 5a, 5b and the position accuracy of the opposing substrate 2 and the element substrate 3 are cut out from the opposing mother substrate 2A and the element mother substrate 3A.

因此,依據本實施形態之製造方法,即使液晶顯示面板1係成為異形顯示面板時,也可提高偏光膜5a,5b對此種液晶顯示面板1的貼合精度,並且可以良好產 率製造液晶顯示面板1。 Therefore, according to the manufacturing method of this embodiment, even when the liquid crystal display panel 1 is a special-shaped display panel, the adhesion accuracy of the polarizing films 5a, 5b to this liquid crystal display panel 1 can be improved, and the production can be good. Rate manufacturing liquid crystal display panel 1.

又,本發明並非必然限定於上述實施形態者,在不超出本發明旨趣之範圍可施以各種變更。 In addition, the present invention is not necessarily limited to the above-mentioned embodiments, and various changes can be added without departing from the scope of the present invention.

具體而言,上述實施形態中,係以對向用母基板2A側、元件用母基板3A側的順序進行各偏光膜5a,5b之裁切以及各母基板2A,3A的裁切,亦可以與前述相反的順序,亦即,以元件用母基板3A側、對向用母基板2A側之順序進行各偏光膜5b,5a之裁切、以及各母基板3A,2A的裁切。 Specifically, in the above embodiment, the cutting of the polarizing films 5a, 5b and the cutting of the mother substrates 2A, 3A may be performed in the order of the opposing mother substrate 2A side and the element mother substrate 3A side. In the reverse order to the foregoing, that is, the cutting of the polarizing films 5b, 5a and the cutting of the mother substrates 3A, 2A are performed in the order of the element mother substrate 3A side and the facing mother substrate 2A side.

而且,於上述實施形態中,係例示在製作(準備)面板製作用基板10之後,將貼合於對向用母基板2A或元件用母基板3A的外表面之偏光膜5a,5b進行裁切之情形,惟亦可在製作面板製作用基板10之前,使用與上述實施形態相同的方法將貼合於對向用母基板2A或元件用母基板3A的外表面之偏光膜5a,5b進行裁切。 Furthermore, in the above-mentioned embodiment, it is exemplified that after the substrate 10 for panel production is produced (prepared), the polarizing films 5a, 5b bonded to the outer surface of the opposed mother substrate 2A or the element mother substrate 3A are cut out In this case, it is also possible to cut the polarizing films 5a, 5b attached to the outer surface of the opposing mother substrate 2A or the element mother substrate 3A using the same method as the above-mentioned embodiment before the panel production substrate 10 is produced. cut.

此種情況下,係將偏光膜5a,5b裁切去除之後,經由密封材7接合對向用母基板2A與元件用母基板3A,並注入液晶,製作面板製作用基板10。之後,使用與上述實施形態相同的方法,只要進行對向用母基板2A與元件用母基板3A之裁切即可。 In this case, after the polarizing films 5a and 5b are cut and removed, the opposed mother substrate 2A and the element mother substrate 3A are joined via the sealing material 7 and liquid crystal is injected to produce the panel production substrate 10. After that, using the same method as in the above-mentioned embodiment, it is only necessary to perform cutting of the opposed mother substrate 2A and the element mother substrate 3A.

而且,上述實施形態中,雖例示偏光膜5a,5b作為光學膜,惟光學膜只要是包含偏光膜5a,5b者即可,亦可同時積層偏光膜5a,5b與例如光學補償膜和增亮膜、抗反射膜等功能膜。 In addition, in the above embodiment, although the polarizing films 5a and 5b are exemplified as the optical films, the optical films may include polarizing films 5a and 5b, and the polarizing films 5a and 5b may be laminated together with, for example, optical compensation films and brightness enhancement films. Functional films such as film and anti-reflection film.

而且,第一對位記號AM1與第二對位記號 AM2之一部分亦可共有化。亦即,可以在第一對位記號AM1的一部分附加表示單元1A的位置之作為第二對位記號AM2的功能、在第二對位記號的一部分附加表示偏光膜5a,5b(光學膜)的貼合位置之作為第一對位記號AM1的功能。 Moreover, the first alignment mark AM1 and the second alignment mark A part of AM2 can also be shared. That is, a part of the first alignment mark AM1 may be added to indicate the position of the unit 1A as a function of the second alignment mark AM2, and a part of the second alignment mark may be added to indicate the polarizing film 5a, 5b (optical film) The laminating position serves as the first alignment mark AM1.

而且,液晶顯示面板1不限於透射型,亦可為反射型。為反射型時,因為係僅於對向基板2配置有偏光膜5a(光學膜)之結構,故變得不需上述第6圖及第7圖所示之步驟。 Moreover, the liquid crystal display panel 1 is not limited to the transmissive type, and may be a reflective type. In the case of the reflective type, since the polarizing film 5a (optical film) is arranged only on the counter substrate 2, the steps shown in Figs. 6 and 7 above are not required.

而且,對於對向用母基板2A、元件用母基板3A的裁切,除了上述使用刀具之劃線裁切加工以外,還可以使用別的裁切方法。具體而言,可使用雷射光裁切加工和噴水式裁切加工等等之裁切方法。 Furthermore, for cutting of the facing mother substrate 2A and the element mother substrate 3A, other cutting methods can be used in addition to the above-mentioned scribing cutting process using a cutter. Specifically, cutting methods such as laser cutting and water jet cutting can be used.
