Description

表示パネル用基板Display panel substrate
　本発明は、表示パネルを製造するための表示パネル用基板に関する。 The present invention relates to a display panel substrate for manufacturing a display panel.
　一般的に、液晶表示パネルは、表示パネル用基板を所定の大きさに切断することによって複数製造される。表示パネル用基板は、透光性を有し、互いに対向する二枚の基板を有する。基板は、中央部分に位置し、画像を表示する表示領域と、該表示領域の外周に設けてあり、遮光層を設けた額縁領域と、該額縁領域の外側に位置し、表示パネルの製造時に切り離される切離し領域とに分けられる。両基板間において、切離し領域及び額縁領域には、基板間の間隔を保つべく、スペーサが設けられる（例えば特許文献１参照）。 Generally, a plurality of liquid crystal display panels are manufactured by cutting a display panel substrate into a predetermined size. The display panel substrate is light-transmitting and has two substrates facing each other. The substrate is located in the central portion and is provided on the display area for displaying an image, on the outer periphery of the display area, on the frame area provided with a light shielding layer, on the outside of the frame area, and at the time of manufacturing the display panel It is divided into separation areas to be separated. Between the two substrates, spacers are provided in the separation region and the frame region in order to keep the space between the substrates (see, for example, Patent Document 1).
　近年では、液晶注入時間を短縮して製造プロセスの簡略化を実現する手法として、一方の基板上に液晶を滴下してから二枚の基板を貼り合わせる滴下注入法（ＯＤＦ（One Drop Filling）法）が用いられるようになっている。ＯＤＦ法を用いた液晶注入では、フォトリソグラフィ法を用いて一方の基板上に、柱状スペーサを設ける。そしていずれかの基板にシール材を設け、シール材の内側に液晶を滴下し、二枚の基板を貼り合わせる。 In recent years, as a technique for shortening the liquid crystal injection time and simplifying the manufacturing process, a drop injection method (ODF (One Drop Drop Filling) method) in which a liquid crystal is dropped onto one substrate and then the two substrates are bonded together. ) Is used. In liquid crystal injection using the ODF method, columnar spacers are provided on one substrate using a photolithography method. Then, a sealing material is provided on one of the substrates, liquid crystal is dropped inside the sealing material, and the two substrates are bonded to each other.
　切離し領域にはマークが設けられ、このマークを撮像装置によって撮像し、撮像した画像を、制御部に予め登録してあるマークの画像と比較して、基板の位置を算出する。そして算出結果に基づいて、二つの基板の相対位置を調整し、両基板の縁部分をシール材によって貼り合わせ、各表示パネルに分断し、切離し領域を切離す。 A mark is provided in the separation area, and the mark is picked up by an image pickup device. The picked-up image is compared with an image of a mark registered in advance in the control unit to calculate the position of the substrate. Then, based on the calculation result, the relative positions of the two substrates are adjusted, the edge portions of the two substrates are bonded together with a sealing material, divided into each display panel, and the separation region is separated.
　撮像装置によって撮像された画像に、マークのみならずスペーサが存在する場合、制御部は、スペーサをマークの一部と認識する場合があり、マークを精度良く読み取ることができない。そのため、撮像装置の撮像範囲に応じて、マークから所定距離以上離隔させてスペーサを配置している。 When the image picked up by the image pickup apparatus includes not only a mark but also a spacer, the control unit may recognize the spacer as a part of the mark and cannot read the mark with high accuracy. Therefore, the spacer is arranged at a predetermined distance or more away from the mark according to the imaging range of the imaging device.
　表示パネル用基板の製造効率を高めるために、額縁領域に遮光層を形成するマスクにはマークを形成するためのパターンが含まれており、マークは、額縁領域に形成する遮光層と同時に一方の基板に形成される。遮光層の厚さ寸法は基板間距離よりも短く、すなわちマークの厚さ寸法も基板間距離よりも短く、マークと該マークに対向する他方の基板との間には隙間がある。 In order to increase the manufacturing efficiency of the display panel substrate, a mask for forming a light shielding layer in the frame region includes a pattern for forming a mark, and the mark is formed on one of the light shielding layers in the frame region at the same time. Formed on the substrate. The thickness dimension of the light shielding layer is shorter than the distance between the substrates, that is, the thickness dimension of the mark is also shorter than the distance between the substrates, and there is a gap between the mark and the other substrate facing the mark.
特開２００１－５１２６６号公報JP 2001-512266 A
　前述したように、スペーサはマークから所定距離以上離隔しているため、マークの周囲には、基板間の間隔を保持するための部材が無く、またマークと他方の基板との間に隙間が発生している。基板同士は真空圧着されており、スペーサ、シール等の支えの無い箇所で撓む。この撓みによって基板間の厚みにムラが生じ、分断された後もこのムラが継続し、表示領域において表示ムラを生じさせる。 As described above, since the spacer is separated from the mark by a predetermined distance or more, there is no member around the mark to maintain the distance between the substrates, and a gap is generated between the mark and the other substrate. is doing. The substrates are vacuum-bonded to each other and bend at unsupported locations such as spacers and seals. This bending causes unevenness in the thickness between the substrates, and this unevenness continues even after being divided, causing display unevenness in the display area.
　本発明は斯かる事情に鑑みてなされたものであり、表示領域における表示ムラの発生を防止することができる表示パネル用基板を提供することを目的とする。 The present invention has been made in view of such circumstances, and an object of the present invention is to provide a display panel substrate that can prevent display unevenness in a display area.
　本発明に係る表示パネル用基板は、互いに対向しており、対向間に封入物が封入される二つの基板と、一方の基板の表示領域の外側に設けてあるマークと、前記二つの基板の間に配してあり、前記マークから所定距離以上離隔させて配してあるスペーサとを備える表示パネル用基板において、前記マークと該マークが設けられた一方の基板に対向する他方の基板との間に、該他方の基板を支持する支持部が設けてあることを特徴とする。 The display panel substrate according to the present invention is opposed to each other, two substrates in which an inclusion is enclosed between the opposed substrates, a mark provided outside the display area of one substrate, and the two substrates. A display panel substrate comprising a spacer disposed between and spaced apart from the mark by a predetermined distance or more, and the mark and the other substrate facing the one substrate provided with the mark. A support portion for supporting the other substrate is provided between them.
　本発明においては、マークと、該マークに対向する基板との間に支持部を設け、該支持部によって基板を支持する。 In the present invention, a support portion is provided between the mark and the substrate facing the mark, and the substrate is supported by the support portion.
　本発明に係る表示パネル用基板は、前記マークは遮光層を有しており、前記支持部は着色層を有することを特徴とする。 The display panel substrate according to the present invention is characterized in that the mark has a light shielding layer and the support portion has a colored layer.
　本発明においては、前記支持部を着色層によって構成する。表示パネル用基板にはカラーフィルタが設けられ、カラーフィルタを作成する過程において着色層が基板に設けられる。そのため、カラーフィルタを作成するマスクに予め、マークに対応した位置にパターンを形成し、該パターンによって支持部を形成する。 In the present invention, the support portion is constituted by a colored layer. The display panel substrate is provided with a color filter, and a colored layer is provided on the substrate in the process of producing the color filter. Therefore, a pattern is previously formed on the mask for creating the color filter at a position corresponding to the mark, and a support portion is formed by the pattern.

The control unit controls driving of a transfer device that transfers the first glass substrate 10 or the second glass substrate 20 in order to align the relative positions of the two substrates.
　マーク１２と第２ガラス基板２０との間において、マーク１２には十字形状の着色層１３（支持部）が積層している。着色層１３の縦及び横寸法はマーク１２よりも小さく、マーク１２からはみ出さない。マーク１２及び着色層１３の厚さ寸法（第１ガラス基板１０及び第２ガラス基板２０の対向方向における寸法）は、スペーサ１１の厚さ寸法と略同じであり、マーク１２及び着色層１３はスペーサとして機能する。なおマーク１２及び着色層１３の厚さ寸法とは、両者の厚さ寸法の合算値を意味し、この合算値とスペーサ１１の厚さ寸法との差分は１．０μｍ以下である。 Between the mark 12 and the second glass substrate 20, a cross-shaped colored layer 13 (support portion) is laminated on the mark 12. The vertical and horizontal dimensions of the colored layer 13 are smaller than the mark 12 and do not protrude from the mark 12. The thickness dimension of the mark 12 and the colored layer 13 (the dimension in the opposing direction of the first glass substrate 10 and the second glass substrate 20) is substantially the same as the thickness dimension of the spacer 11, and the mark 12 and the colored layer 13 are spacers. Function as. In addition, the thickness dimension of the mark 12 and the colored layer 13 means the total value of both thickness dimensions, and the difference between this total value and the thickness dimension of the spacer 11 is 1.0 μm or less.
　マーク１２の周囲にはスペーサ１１が設けられておらず、このスペーサ１１が設けられていない領域（以下マーク領域１２ａという）は、撮像装置の撮像範囲に基づいて定まる。マーク１２から１．０ｍｍ離れた位置までが撮像範囲である場合、例えば一辺の長さｄが２．０ｍｍ以上であり、正方形状をなす領域がマーク領域１２ａとして設定され、その中心部にマーク１２が位置する。なおマーク領域１２ａは正方形状に限定されるものではなく、円形その他の形状でもよい。またマーク領域１２ａは、撮像装置の撮像範囲に基づいて定まり、マーク領域１２ａの寸法は上記寸法に限定されるものではない。 The spacer 11 is not provided around the mark 12, and the area where the spacer 11 is not provided (hereinafter referred to as the mark area 12a) is determined based on the imaging range of the imaging apparatus. When the imaging range extends to a position distant from the mark 12 by 1.0 mm, for example, the length d of one side is 2.0 mm or more, and a square area is set as the mark area 12a. Is located. The mark region 12a is not limited to a square shape, and may be a circle or other shapes. The mark area 12a is determined based on the imaging range of the imaging apparatus, and the dimension of the mark area 12a is not limited to the above dimensions.
　なお表示パネルは以下のようにして製造される。第１ガラス基板１０の一面において、遮光層が設けられ、このときマーク１２も形成される。また第１ガラス基板１０には着色層が設けられ、遮光層によって形成された枠を窓としたカラーフィルタが形成される。カラーフィルタの形成時に、マーク１２の上にも着色層１３が積層する。また第１ガラス基板１０の一面における額縁領域１ｂ及び切離し領域１ｃにスペーサ１１が設けられる。 The display panel is manufactured as follows. On one surface of the first glass substrate 10, a light shielding layer is provided, and at this time, the mark 12 is also formed. Further, the first glass substrate 10 is provided with a colored layer, and a color filter having a window formed by a light shielding layer as a window is formed. When the color filter is formed, the colored layer 13 is also laminated on the mark 12. Spacers 11 are provided in the frame region 1b and the separation region 1c on one surface of the first glass substrate 10.
　また第１ガラス基板１０又は第２ガラス基板２０の一面における額縁領域１ｂにシール材１５が設けられ、シール材１５の内側に液晶が滴下される。 Also, the sealing material 15 is provided in the frame region 1b on one surface of the first glass substrate 10 or the second glass substrate 20, and the liquid crystal is dropped inside the sealing material 15.
　そして第１ガラス基板１０及び第２ガラス基板２０それぞれの一面を対向させる。撮像装置によってマーク１２が撮像され、撮像された画像は、制御部に予め登録してあるマークの画像と比較され、基板の位置が算出される。そして算出結果に基づいて、両基板の相対位置が調整され、第１ガラス基板１０及び第２ガラス基板２０が貼り合わされ、表示パネル用基板１が製造される。その後、表示パネル用基板１を、所定面積を有する各パネルに分断し、切離し領域１ｃを切り離して、表示パネルが製造される。なお上記各工程は、表示パネルを製造することができる限りにおいて、その順番を入れ替えるか又は省略することができる。 Then, one surface of each of the first glass substrate 10 and the second glass substrate 20 is opposed. The mark 12 is picked up by the image pickup device, and the picked-up image is compared with an image of a mark registered in advance in the control unit, and the position of the substrate is calculated. Then, based on the calculation result, the relative positions of the two substrates are adjusted, the first glass substrate 10 and the second glass substrate 20 are bonded together, and the display panel substrate 1 is manufactured. Thereafter, the display panel substrate 1 is divided into each panel having a predetermined area, and the separation region 1c is separated to manufacture the display panel. In addition, as long as the said process can manufacture a display panel, the order can be replaced or abbreviate | omitted.
　図４Ａは表示パネル用基板１の構成を一部変更した変更例に係るマーク１２を略示する平面図、図４Ｂは図４Ａに示すＢ－Ｂ線を切断線とした断面図である。着色層１３は十字形状ではなく、正方形状に構成されており、十字形状のマーク１２の中央部分に積層している。また着色層１３の縦及び横寸法は、マーク１２の中央部分よりも小さく、マーク１２からはみ出していない。 4A is a plan view schematically showing a mark 12 according to a modified example in which the configuration of the display panel substrate 1 is partially changed, and FIG. 4B is a cross-sectional view taken along the line BB shown in FIG. 4A. The colored layer 13 has a square shape instead of a cross shape, and is laminated at the center of the cross-shaped mark 12. The vertical and horizontal dimensions of the colored layer 13 are smaller than the center portion of the mark 12 and do not protrude from the mark 12.
　図５Ａは表示パネル用基板１の構成を一部変更した他の変更例に係るマーク１２を略示する平面図、図５Ｂは図５Ａに示すＢ－Ｂ線を切断線とした断面図である。マーク１２の形状は円環状をなし、マーク１２の上に円環状の着色層１３が積層している。着色層１３の径方向寸法は、マーク１２部分よりも小さく、マーク１２からはみ出していない。このように、マーク１２の形状には、種々の形状を適用することができ、マーク１２の形状は特定の形状に限定されない。 FIG. 5A is a plan view schematically showing a mark 12 according to another modified example in which the configuration of the display panel substrate 1 is partially changed, and FIG. 5B is a cross-sectional view taken along line BB shown in FIG. 5A. . The mark 12 has an annular shape, and an annular colored layer 13 is laminated on the mark 12. The radial dimension of the colored layer 13 is smaller than the mark 12 portion and does not protrude from the mark 12. Thus, various shapes can be applied to the shape of the mark 12, and the shape of the mark 12 is not limited to a specific shape.
　実施の形態１に係る表示パネル用基板１にあっては、マーク１２と、該マーク１２に対向する基板との間に着色層１３（支持部）を設け、該着色層１３によって基板を支持するので、マーク１２を設けた基板が過剰に撓み、表示ムラが発生することを防ぐことができる。 In the display panel substrate 1 according to the first embodiment, the colored layer 13 (support portion) is provided between the mark 12 and the substrate facing the mark 12, and the substrate is supported by the colored layer 13. Therefore, it is possible to prevent the substrate provided with the mark 12 from being excessively bent and causing display unevenness.
　表示パネル用基板１にはカラーフィルタが設けられ、カラーフィルタを作成する過程において着色層１３が基板に設けられる。そのため、カラーフィルタを作成するマスクに予め、マーク１２に対応した位置にパターンを形成し、該パターンによって、マーク１２の上に着色層１３（支持部）を形成する。そのためマーク１２の上に着色層１３を設けるために別途マスクを用意する必要が無く、着色層１３を効率よく製造することができ、表示パネル用基板１の製造効率、ひいては表示パネルの製造効率を向上させることができる。また着色層１３はマーク１２からはみ出していないので、制御部によるマーク１２の読取不良の発生を防止することができる。着色層１３がマーク１２からはみ出している場合、撮像されたマーク１２の形状が、登録されたマーク１２の形状と異なると制御部が判断し、読取不良が発生するおそれがある。 The display panel substrate 1 is provided with a color filter, and a colored layer 13 is provided on the substrate in the process of producing the color filter. Therefore, a pattern is formed in advance on a mask corresponding to the mark 12 for forming a color filter, and a colored layer 13 (supporting portion) is formed on the mark 12 by the pattern. Therefore, it is not necessary to prepare a separate mask for providing the colored layer 13 on the mark 12, the colored layer 13 can be efficiently manufactured, and the manufacturing efficiency of the display panel substrate 1 and thus the manufacturing efficiency of the display panel can be improved. Can be improved. Further, since the colored layer 13 does not protrude from the mark 12, it is possible to prevent the reading failure of the mark 12 by the control unit. When the colored layer 13 protrudes from the mark 12, the control unit determines that the shape of the captured mark 12 is different from the registered shape of the mark 12, which may cause reading failure.
　またマーク１２及び着色層１３の厚み寸法と、スペーサ１１の厚み寸法との差分を１．０μｍ以下に設定することによって、マーク１２及び着色層１３はスペーサ１１として機能し、表示パネル用基板１において撓みが発生することを抑制することができる。またマーク１２とスペーサ１１との離隔距離を１．０ｍｍ以上に設定することによって、撮像装置にてマーク１２を撮像した場合、スペーサ１１が撮像範囲から外れ、制御部によるマーク１２の読取不良が発生することを回避することができる。 Further, by setting the difference between the thickness dimension of the mark 12 and the colored layer 13 and the thickness dimension of the spacer 11 to 1.0 μm or less, the mark 12 and the colored layer 13 function as the spacer 11. It is possible to suppress the occurrence of bending. In addition, by setting the separation distance between the mark 12 and the spacer 11 to 1.0 mm or more, when the mark 12 is imaged by the imaging device, the spacer 11 is out of the imaging range, and the reading of the mark 12 by the control unit is generated. Can be avoided.
　なお着色層１３に代えて、第２基板に向けて突出した樹脂製の柱を、支持部としてマーク１２の上に設けてもよい。スペーサ１１は遮光層によって形成されるか又は遮光層上に形成される場合があるが、この場合、前記遮光層とマーク１２とは形状が異なり、両者は区別される。 In addition, it may replace with the colored layer 13 and may provide the resin-made pillar protruded toward the 2nd board | substrate on the mark 12 as a support part. The spacer 11 may be formed of a light shielding layer or may be formed on the light shielding layer. In this case, the light shielding layer and the mark 12 have different shapes and are distinguished from each other.
