Field of the Invention
The present invention, a pair of stuck opposite one another at appropriate intervals crystal is sealed between the glass substrates, the liquid crystal display panel polarization plate is pasted respectively on the surface of each glass substrate It relates to the manufacturing method.

この場合、図３（ｂ）に示すように、前工程において、各マザーガラス基板の裏面に実施された所定の加工処理が適切でない領域が存在する場合には、その領域に対応する各マザーガラス基板の表面には、偏光板１４は、それぞれ貼り付けられない。 In this case, as shown in FIG. 3B, if there is a region where the predetermined processing performed on the back surface of each mother glass substrate is not appropriate in the previous step, each mother glass corresponding to that region The polarizing plate 14 is not attached to the surface of the substrate.

本願では、ガラス基板の液晶注入前に、マザーガラス基板に偏光板を貼り付ける液晶パネルの製造法を一例として説明するが、一対のマザーガラス基板のいずれかに、マザーガラス同士を貼り合わせるためのシール剤で囲まれた領域に液晶を滴下した後、マザーガラス基板同士を貼り合わせ、その後、マザーガラス基板に偏光板を貼り付ける液晶パネルの製造法もある。 In the present application, before liquid crystal injection of a glass substrate, it is described the preparation of a liquid crystal panel pasted polarizing plate on the mother glass substrate as an example, to one of the pair of mother glass substrates, for bonding the mother glass together There is also a manufacturing method of a liquid crystal panel in which mother glass substrates are bonded to each other after liquid crystal is dropped in a region surrounded by a sealing agent, and then a polarizing plate is bonded to the mother glass substrate.

【課題を解決するための手段】
本発明の液晶表示パネルの製造方法は、適当な間隔をあけて相互に対向して貼り合わせられた一対のガラス基板の間に液晶が封入される、各ガラス基板の表面に偏光板がそれぞれ貼り付けられた液晶表示パネルの製造方法であって、液晶表示パネルを構成する複数のガラス基板に対応した大きさの一対のマザーガラス基板それぞれに、各液晶表示パネルのガラス基板とされる各領域毎にそれぞれ所定の加工を実施した後に、各マザーガラス基板同士を、適当な間隔をあけて相互に貼り合わせる貼り合わせ工程と、各マザーガラス基板において、所定の加工が適切に実施された領域の表面に、偏光板をそれぞれ貼り付けるとともに、所定の加工が適切に実施されていない領域の表面に、偏光板と同様の厚さおよび形状のダミーフィルムを貼り付ける工程と、各マザーガラス基板の表面における各領域間にスクライブラインを形成する工程と、を包含することを特徴とする。 [0013]
[Means for Solving the Problems]
In the method of manufacturing a liquid crystal display panel according to the present invention, a polarizing plate is attached to the surface of each glass substrate in which liquid crystal is sealed between a pair of glass substrates bonded facing each other at appropriate intervals. A manufacturing method of the attached liquid crystal display panel, wherein each of a plurality of mother glass substrates of a size corresponding to a plurality of glass substrates constituting the liquid crystal display panel is used as the glass substrate of each liquid crystal display panel Bonding the mother glass substrates to each other at appropriate intervals after the predetermined processing is performed, and the surface of the region where the predetermined processing is appropriately performed in each mother glass substrate. Together with a polarizing plate, and a dummy film of the same thickness and shape as the polarizing plate is attached to the surface of the region where predetermined processing is not properly performed. And that step, characterized in that it comprises a step of forming a scribe line between the areas in the surface of the mother glass substrate.

すなわち、各マザーガラス基板１１の検査工程において、液晶表示パネルとされるいずれかの領域に、前述の加工工程において適切に加工処理が実施されていない場合には、その適切に加工処理が実施されていない領域が特定されて（図２（ａ）に「×」にて表示している）、その領域に対応したマザーガラス基板１１の表面、および、貼り合わせられた他方のマザーガラス基板１１のその欠陥領域に対応した表面に、それぞれダミーフイルム１５が貼り付けられる。従って、各マザーガラス基板１１の表面における適切に加工処理されていない領域に対応して貼り付けられたダミーフィルム１５同士は、相互に対向した状態になっている。 That is, in the inspection step of each mother glass substrate 11, when the processing is not properly performed in any of the regions to be the liquid crystal display panel, the processing is appropriately performed. An area not shown is specified (indicated by “x” in FIG. 2A), and the surface of the mother glass substrate 11 corresponding to the area and the other mother glass substrate 11 bonded. Dummy films 15 are attached to the surfaces corresponding to the defect areas, respectively. Therefore, the dummy films 15 attached corresponding to the area which is not appropriately processed on the surface of each mother glass substrate 11 are opposed to each other.
