【発明の詳細な説明】 DETAILED DESCRIPTION OF THE INVENTION

【0001】 [0001]

【産業上の利用分野】本発明は液晶表示板を構成するガラス基板(上下電極板)の貼り合せ方法及び貼り合せ装置に関する。 The present invention relates to a combined method and bonding apparatus bonding the glass substrate (the upper and lower electrode plates) constituting the liquid crystal display panel.

【0002】 [0002]

【従来の技術】液晶表示板(LCD )は、透明導電性電極をコ―トした2枚のガラス基板間に数μmのスペ―サを用いてシ―ル材の内側に液晶を封入したもので、その2 A liquid crystal display panel (LCD) is a transparent conductive electrode co - those in which liquid crystal is sealed inside the sealing material - you encountered a two glass substrates between several μm of space - with support sheet in, Part 2
枚のガラス基板は位置合せマ―クによって狂いなく貼り合せられている。 Like the glass substrate of the alignment Ma - it is bonded not have mad by click. ところで、従来の2枚のガラス基板の貼り合せは、予じめガラス基板に施こされている位置合せマ―クを顕微鏡とカメラからなるマ―ク検出手段の検出デ―タで駆動され、X方向、Y方向及びθ方向に移動する下定盤の移動調節で粗合せ及び微合せを行ない、マ―ク合せを完了した時点で2枚のガラス基板を加圧するというものである。 Incidentally, bonding of conventional two glass substrates are aligned Ma is strained facilities to pre Ji because the glass substrate - is driven by motor, - the detection data of click detector - Ma comprising a click from the microscope and camera X direction, performs coarse combined and fine combined with the movement regulation of the lower platen that moves in the Y direction and the θ direction, Ma - is that pressurizing the two glass substrates at the time of completing the click fit.

【0003】 [0003]

【発明が解決しようとする課題】上述した従来の貼り合せ方法にあっては、マ―ク合せを完了した後、加圧して貼り合せるが、その加圧処理の時、重合されたガラス基板相互にズレを生じることがある。 In the conventional bonding method described above in which [0004], Ma - After completing the click fit, but bonded by pressurizing, when the pressure treatment, the polymerized glass substrates each other which may cause deviation in. そのため従来は加圧時のズレ量が許容範囲内であるか否かを再度チェックし、その結果によって次工程の処理を行なうもので、面倒な作業を有する。 Therefore conventional checks whether the deviation amount of pressurization is within the allowable range again, the result by performs the processing of the next step, with a troublesome work. 又、マーク合せを完了した後、上下基板をその状態に保って完全に固定する貼り合せ固定手段に供給するため、上下基板は仮止めするが、その仮止めはシール部材の外側に位置して紫外線硬化型樹脂を点付けして行うもので、その為の塗布作業が必要で有り、 Further, after completing the alignment mark, for supplying the upper and lower substrates in bonding fixation means completely secured kept in that state, the upper and lower substrate is temporarily fixed, the temporary fixing is located outside of the sealing member performs an ultraviolet curable resin to put a point, there is required the coating operations Therefore,
作業に手数を要すると共に、仮止めした後、完全な固定を行う位置まで上下基板を移動させなければならず、その結果、その移送工程で位置ズレが生じるといった問題点を有する。 Working together requires troublesome to, after temporary fixing, it is necessary to move the upper and lower substrates to a position where a complete fixation, the result has a problem that positional deviation at the transfer process occurs.

【0004】又、上記の方法を実施する貼り合せ装置は、上下基板のマーク合せ及び仮止めの機能は装備しているが、完全に固定する為の固定手段は備えておらず、 [0004] In addition, the method described above bonding apparatus for implementing the will, but mark fit and function of temporary stop of the upper and lower substrates is equipped, fixed means for completely fixed is not provided,
別途独立した貼り合せ固定装置が必要となり、一連の貼り合せラインは大型化するといった問題点を有する。 An independent bonding fixation device is required, a series of bonding lines have a problem that size.

【0005】本発明は上述した従来の技術の有する問題点に鑑みてなされたもので、その目的とする処は、高精度の貼り合せを能率良く行なうことが出来る貼り合せ方法、及び貼り合せ装置を提供することにある。 [0005] The present invention has been made in view of the problems of the prior art described above, treatment is bonding method can be performed with good efficiency the bonding of high precision and an object, and bonding apparatus It is to provide a.

【0006】 [0006]

【課題を解決するための手段】上記目的を達成するために、本発明における貼り合せ方法は、予め所定のパターンの電極及び位置合せマークがパターニングされ、且つ表面にスペーサを散在した一方の基板と、電極及び位置合せマークがパターニングされ、且つ周縁に沿って紫外線硬化型樹脂から成るシール材を塗布した他方の基板を、そのシール材が基板間に位置するようにして重ね、 To achieve the above object, according to the solution to ## combined method paste in the present invention, the patterned electrode and alignment mark in advance a predetermined pattern, and the one substrate interspersed spacers on the surface , electrodes and alignment marks are patterned, and the other substrate with a seal material is applied consisting of ultraviolet curable resin along the periphery, overlapping the sealing material so as to be positioned between the substrates,
両基板の位置合せマークのマーク合せを加圧しながら行い、マーク合せが完了した時点でシール材の塗布部分に紫外線を照射して両基板を貼り合せ一体化することを特徴とする。 Performed while pressurizing the mark combined alignment marks of the substrates, characterized in that it combined integrally bond the two substrates by irradiating ultraviolet rays to the coating portion of the seal member at the time the mark combined is completed.

【0007】又、その貼り合せ装置は、機枠の下側に固定台板が設けられ、その固定台板の上方に可動台板が上下動自在に取付けられ、且つ前記固定台板の上に下定盤を、可動台板の下に上定盤を夫々水平方向に移動可能に取付けると共に、下定盤内に、紫外線を上方に向けて照射する紫外線照射部を設けたことを特徴とする。 [0007] In addition, the bonding device includes a fixed base plate is provided below the machine frame, the movable base plate is mounted for vertical movement above the fixed base plate, and on the fixing base plate the lower surface plate, with mounting the upper platen to be movable in respective horizontally below the movable base plate, in the lower platen, characterized in that a UV irradiation unit for irradiating ultraviolet rays upwards. 可動台板の上下動は、可動台板を所定位置まで上げ下げする手段と、二枚の基板を加圧する手段を別々にした形態、或いは上げ下げと加圧を単一の手段で行う形態のいずれでも良いものである。 Vertical movement of the movable base plate, means for raising and lowering the movable base plate to a predetermined position in a form to separate the means for pressurizing the two substrates, or raise and lower the pressure in any form performed by a single means it is a good thing.

【0008】上記の装置における下定盤及び上定盤の水平方向への移動としては、下定盤をX方向、Y方向のうちの何れか一方の方向とθ方向に移動可能とし、上定盤は下定盤が移動しないX方向又はY方向に移動するようにしたり、或いは、下定盤のみをX方向、Y方向に移動するようにしても良いものである。 [0008] As the movement in the horizontal direction of the lower platen and the upper platen in the apparatus, and movable lower platen X direction, in either direction and θ direction of the Y-direction, the upper surface plate or as the lower surface plate moves in X or Y direction does not move, or those may be moved only in the X direction, the Y direction lower platen.

【0009】 [0009]

【作用】上記の手段によれば、一方の基板に施こされるシール材を紫外線硬化型樹脂で形成したので、上・下側基板を加圧しながらマーク合せを行うことで、上側基板と下側基板との間のギャップを一定にするすると同時に紫外線を照射することで上・下側基板の間で潰されたシール材が硬化して、上側基板と下側基板の貼り合せ固定が行なわれる。 According to the above means, since the sealing material to be strained facilities on one substrate formed by the ultraviolet curable resin, by performing the mark combined while pressurizing the upper and lower substrate, the upper substrate and the lower and curing the upper and lower side seal member mashed between substrate by irradiating to simultaneously ultraviolet to a constant gap between the side board, bonding fixation of the upper and lower substrates is performed .

【0010】 [0010]

【発明の効果】本発明の貼り合せ方法は、以上詳述したようにシール材を紫外線硬化型樹脂で形成し、上下の基板を加圧した状態でマーク合せを行ない、マークが合った状態でシール材に紫外線を照射するようにしたものであるから、高精度な貼り合せ固定を能率良く行なうことかず出来る。 Bonding method of the present invention exhibits, in detail the way the sealing material is formed of an ultraviolet curable resin or performs mark combined upper and lower substrates in pressurized state, in a state where the mark suits since is obtained so as to irradiate ultraviolet rays onto the sealing material, it can not either be efficiently performed with high precision bonding fixation.

【0011】又、上記の貼り合せを行なう貼り合せ装置は、下定盤に、上方に紫外線を照射する紫外線照射部を装着したので、加圧しながらマーク合せを行ない、しかもマーク合せを完了した状態の上下基板を上定盤と下定盤とで挟持したまま紫外線を照射出来ることになり、従って別途固定手段は不要となり、貼り合せラインのコンパクト化を達成出来るものである。 [0011] Also, bonded performs bonding of the apparatus, the lower polishing plate, so wearing the ultraviolet irradiation unit for irradiating ultraviolet rays upwards, performs mark combined under pressure, yet in a state of complete mark combined will be the upper and lower substrates can be irradiated with ultraviolet rays while held between the upper platen and the lower platen, thus those separately fixing means is not required, thereby achieving a compact bonding line.
