Description

本発明は、液晶パネルなどに用いられる基板への配向膜の液滴吐出方法及び液滴吐出装置に関するものである。   The present invention relates to a droplet discharge method and a droplet discharge device for an alignment film onto a substrate used in a liquid crystal panel or the like.

近年、平面型の表示装置として例えば液晶パネルを備えた液晶表示装置が広く用いられている。液晶パネルは、２枚の基板の電極の間に液晶を封止し、これらの電極から液晶に対して電圧を印加し表示を行うものであり、電圧を印加した時に均一な表示を行うために、液晶分子にプレチルト角を予め与えるものとして配向膜がそれぞれの基板に形成されている。配向膜の形成は、電極等が形成された基板上に配向膜の材料からなる薄膜をオフセット印刷により形成する方法の他に、例えば図４に示すような長尺状のインクジェットヘッド５０を用いて配向膜を形成する方法がある。   In recent years, for example, a liquid crystal display device including a liquid crystal panel has been widely used as a flat display device. A liquid crystal panel seals liquid crystal between electrodes on two substrates and applies a voltage to the liquid crystal from these electrodes to perform display. In order to perform uniform display when a voltage is applied Alignment films are formed on the respective substrates to preliminarily give a pretilt angle to the liquid crystal molecules. The alignment film is formed by using, for example, a long inkjet head 50 as shown in FIG. 4 in addition to the method of forming a thin film made of the alignment film material on the substrate on which the electrodes and the like are formed by offset printing. There is a method of forming an alignment film.

図４（ａ）に示されるように、インクジェットヘッド５０には、一列に並んだ複数のノズル５１が設けられており、このインクジェットヘッド５０を基板５２に対して矢印Ｄに示す方向に相対的に移動させて、各ノズル５１から配向膜の材料の液滴５３が吐出される。滴下された液滴５３は着弾の瞬間に基板５２上で濡れ広がり、隣接する液滴５３同士が接触すると、その接触位置からそれらの液滴５３同士が繋がって一体となり、図４（ｂ）に示されるように、単一の薄膜５４として形成される。その後、乾燥などの所定の工程を経ることで、基板５２上に配向膜が形成される。   As shown in FIG. 4A, the inkjet head 50 is provided with a plurality of nozzles 51 arranged in a line, and the inkjet head 50 is relatively positioned in the direction indicated by the arrow D with respect to the substrate 52. The liquid droplets 53 of the material of the alignment film are discharged from each nozzle 51 by being moved. The dropped liquid droplet 53 spreads on the substrate 52 at the moment of landing, and when adjacent liquid droplets 53 come into contact with each other, the liquid droplets 53 are connected to each other from the contact position, and as shown in FIG. As shown, it is formed as a single thin film 54. Thereafter, an alignment film is formed on the substrate 52 through a predetermined process such as drying.

特開平９−１３８４１０号JP-A-9-138410

しかしながら、完成した液晶パネルを点灯させると、図４（ｃ）に示されるように基板５２に対してノズル５１の移動方向に沿うすじ（ムラ）５５が確認される場合がある。このような表示ムラ５５は、インクジェットヘッド５０の隣り合うノズル５１の間、つまり液滴５３の着弾点間に沿って発生することがわかっている。これは、ちょうど液滴５３が着弾点から濡れ広がって隣の液滴５３に接触するまでに移動した部分に相当しており、この部分の配向膜の膜厚が着弾点位置の配向膜よりも薄く形成されてしまうのである。このような配向膜の膜厚の不均一を解消するには、滴下後の薄膜の膜厚が均一になるまで一定時間放置したり、又は振動手段により振動させて均一にさせることが考えられるが、工程数の増加等により製造コストがアップするという問題があった。   However, when the completed liquid crystal panel is turned on, streaks (unevenness) 55 along the moving direction of the nozzles 51 may be confirmed with respect to the substrate 52 as shown in FIG. It is known that such display unevenness 55 occurs between adjacent nozzles 51 of the ink jet head 50, that is, between the landing points of the droplets 53. This corresponds to the portion where the droplet 53 has moved from the landing point to the point where the droplet 53 has spread and contacted the adjacent droplet 53, and the thickness of the alignment film in this portion is larger than that of the alignment film at the landing point position. It will be thin. In order to eliminate such non-uniform thickness of the alignment film, it may be possible to leave it for a certain period of time until the thickness of the thin film after the dropping becomes uniform or to make it uniform by vibrating it using vibration means. There is a problem that the manufacturing cost increases due to an increase in the number of processes.

そこで、本発明が解決しようとする課題は、上述したように配向膜の膜厚が不均一に形成されても表示ムラが抑制される配向膜の液滴吐出方法及び液滴吐出装置を提供することである。   Accordingly, the problem to be solved by the present invention is to provide a droplet ejection method and a droplet ejection apparatus for an alignment film that can suppress display unevenness even when the alignment film is formed unevenly as described above. That is.

本発明者は種々なる検討の結果、液滴の着弾点間に発生する配向膜の膜厚の不均一な部分は、インクジェットヘッドが移動する方向に沿って形成されることから、この配向膜の膜厚が不均一に形成される方向と、基板に構成される絵素の配列方向とが一致することによる干渉等が原因で、このようなムラが生じることに着目した。そこで、上記課題を解決するため、本発明に係る配向膜の液滴吐出方法は、所定のピッチで配列される複数のノズルを有するインクジェットヘッドを、基板に対して相対的に移動させて前記ノズルから配向膜の液滴を前記基板上に吐出する方法において、前記インクジェットヘッドの前記基板に対して相対的に移動する方向が前記基板に格子状に構成される絵素の配列方向に対して所定角度傾斜されていることを要旨とするものである。   As a result of various studies, the present inventor has found that the uneven portion of the alignment film generated between the landing points of the droplets is formed along the direction in which the inkjet head moves. It has been noted that such unevenness occurs due to interference caused by the alignment of the direction in which the film thickness is formed nonuniformly and the arrangement direction of the picture elements formed on the substrate. Accordingly, in order to solve the above-described problem, an alignment film droplet discharge method according to the present invention moves an inkjet head having a plurality of nozzles arranged at a predetermined pitch relative to a substrate to move the nozzles. In the method of discharging droplets of the alignment film onto the substrate, the direction in which the inkjet head moves relative to the substrate is predetermined with respect to the arrangement direction of the pixels configured in a lattice pattern on the substrate The gist is that the angle is inclined.

また、本発明に係る配向膜の液滴吐出装置は、所定のピッチで配列される複数のノズルを有するインクジェットヘッドと、このインクジェットヘッドを基板に対して相対的に移動させる移動手段とを備えて、前記ノズルから配向膜の液滴を前記基板上に吐出する配向膜の液滴吐出装置において、前記インクジェットヘッドの前記基板に対して相対的に移動する方向が前記基板に格子状に構成される絵素の配列方向に対して所定角度傾斜されていることを要旨とするものである。   The alignment film droplet discharge apparatus according to the present invention includes an inkjet head having a plurality of nozzles arranged at a predetermined pitch, and a moving means for moving the inkjet head relative to the substrate. In the alignment film droplet discharge device for discharging the alignment film droplets from the nozzle onto the substrate, the moving direction of the inkjet head relative to the substrate is configured in a lattice pattern on the substrate. The gist of the invention is that it is inclined at a predetermined angle with respect to the arrangement direction of the picture elements.

上記構成を有する配向膜の液滴吐出方法及び液滴吐出装置によれば、インクジェットヘッドが基板に対して相対的に移動する方向が基板の絵素の配列方向に対して所定角度傾斜されている構成なので、配向膜の膜厚が不均一に形成される方向と、基板に構成される絵素の配列方向とが一致しない。これにより、表示の際のすじ状のムラの発生を抑制することができる。   According to the droplet ejection method and the droplet ejection apparatus for the alignment film having the above configuration, the direction in which the inkjet head moves relative to the substrate is inclined by a predetermined angle with respect to the arrangement direction of the pixels on the substrate. Because of the configuration, the direction in which the film thickness of the alignment film is formed non-uniformly does not match the arrangement direction of the picture elements formed on the substrate. As a result, the occurrence of streak-like unevenness during display can be suppressed.

以下に、本発明に係る配向膜の液滴吐出方法及び液滴吐出装置の実施の形態ついて、図面を参照して詳細に説明する。先ず、本発明に好適に用いられる液晶パネルについて説明する。図３は、液晶パネル１０の平面図と１絵素の断面図の概略構成を示している。図示されるように液晶パネル１０は、絵素がＸ方向及びＹ方向に複数配列された構成になっている。図中の断面図に示されるように、この液晶パネル１０には、一対の相互に対向するガラス基板（ＴＦＴアレイ側基板）２０とガラス基板（カラーフィルター側基板）３０の間に、液晶層４０が形成されている。下側のガラス基板２０上には、１絵素ごとに設けられた絵素電極２１が格子状に配列して形成され、上側のガラス基板３０の下には、ほぼ全面にわたって設けられた共通電極３１が形成されている。   Embodiments of a droplet discharge method and a droplet discharge device for an alignment film according to the present invention will be described below in detail with reference to the drawings. First, a liquid crystal panel suitably used in the present invention will be described. FIG. 3 shows a schematic configuration of a plan view of the liquid crystal panel 10 and a sectional view of one picture element. As shown in the drawing, the liquid crystal panel 10 has a configuration in which a plurality of picture elements are arranged in the X direction and the Y direction. As shown in the sectional view in the figure, the liquid crystal panel 10 includes a liquid crystal layer 40 between a pair of mutually opposed glass substrate (TFT array side substrate) 20 and glass substrate (color filter side substrate) 30. Is formed. On the lower glass substrate 20, picture element electrodes 21 provided for each picture element are arranged in a lattice pattern, and a common electrode provided almost over the entire surface under the upper glass substrate 30. 31 is formed.

各絵素電極２１の周囲には、ソース配線２２と図示しないゲート配線とが相互に直交するように形成されている。ソース配線２２とゲート配線は、その交差部において、ソース配線２２が上側、ゲート配線が下側になるように交差しており、交差部には図示しないＴＦＴ（薄膜トランジスタ）が形成されている。   A source line 22 and a gate line (not shown) are formed around each pixel electrode 21 so as to be orthogonal to each other. The source wiring 22 and the gate wiring intersect at the intersection so that the source wiring 22 is on the upper side and the gate wiring is on the lower side, and a TFT (thin film transistor) (not shown) is formed at the intersection.

絵素電極２１が設けられたガラス基板２０には、この絵素電極２１を覆うように配向膜２３が形成されている。また、共通電極３１が設けられたガラス基板３０には、この共通電極３１を覆うように配向膜３２が形成されている。これら配向膜２３，３２に、絹布等を用いて表面を所定の方向に擦るラビング処理を施すと、ティルト角を形成して液晶分子を配向させることができる。   An alignment film 23 is formed on the glass substrate 20 provided with the picture element electrode 21 so as to cover the picture element electrode 21. An alignment film 32 is formed on the glass substrate 30 provided with the common electrode 31 so as to cover the common electrode 31. When these alignment films 23 and 32 are subjected to a rubbing process in which a surface is rubbed in a predetermined direction using a silk cloth or the like, a tilt angle can be formed to align liquid crystal molecules.

また、ガラス基板２０の絵素電極２１は、通常、層間絶縁膜２４を介して設けられている。一般的に、絵素電極２１及び共通電極３１にはＩＴＯ（indium-tin oxide：インジウム酸化スズ）材料、そして配向膜２３，３２にはポリイミド材料が用いられる。   Further, the pixel electrode 21 of the glass substrate 20 is usually provided through an interlayer insulating film 24. Generally, an ITO (indium-tin oxide) material is used for the pixel electrode 21 and the common electrode 31, and a polyimide material is used for the alignment films 23 and 32.

共通電極３１が設けられたガラス基板３０には、ブラックマトリクス３３が形成されている。このブラックマトリクス３３により、ガラス基板３０側のソース配線２２及びゲート配線等が形成された領域が遮光されるようになっている。また、このガラス基板３０には、各絵素毎に赤色（Ｒ）、緑色（Ｇ）及び青色（Ｂ）のうちのいずれか１色のカラーフィルタ３４が形成されている。   A black matrix 33 is formed on the glass substrate 30 on which the common electrode 31 is provided. The black matrix 33 shields light from a region where the source wiring 22 and the gate wiring on the glass substrate 30 side are formed. The glass substrate 30 is provided with a color filter 34 of any one of red (R), green (G), and blue (B) for each picture element.

図１は、上述した構成の液晶パネル１０の例えばガラス基板（カラーフィルター側基板）３０への配向膜３２の形成に用いられる液滴吐出装置の概略構成を示した図である。図示される液滴吐出装置１は、インクジェットヘッド２と搬送ステージ３を備えている。長尺状のインクジェットヘッド２には、タンク４から供給管５を介して配向膜３２の材料を含む配向膜溶液（例えば、ポリイミド樹脂５％，溶剤９５パーセント）６が供給される。   FIG. 1 is a diagram showing a schematic configuration of a droplet discharge device used for forming an alignment film 32 on, for example, a glass substrate (color filter side substrate) 30 of the liquid crystal panel 10 having the above-described configuration. The illustrated droplet discharge apparatus 1 includes an inkjet head 2 and a transport stage 3. An alignment film solution (for example, 5% polyimide resin and 95% solvent) 6 containing the material of the alignment film 32 is supplied from the tank 4 through the supply pipe 5 to the long inkjet head 2.

このインクジェットヘッド２には、複数のノズル２ａがピッチＡで配列されている。それぞれのノズル２ａには図示しないピエゾ素子が備えられており、制御回路７からの制御信号によって、任意のノズル２ａから配向膜溶液６の液滴を吐出することが可能になっている。   In the ink jet head 2, a plurality of nozzles 2 a are arranged at a pitch A. Each nozzle 2 a is provided with a piezo element (not shown), and a droplet of the alignment film solution 6 can be discharged from an arbitrary nozzle 2 a by a control signal from the control circuit 7.

また、制御回路７は、ガラス基板３０が載置された搬送ステージ３を矢印Ｂ方向に移動させる際の速度等を制御する。搬送ステージ３には、ガラス基板３０を搬送ステージ３の移動方向に対して斜めに配置するためのガイド３ａが、ガラス基板３０の四辺を支持するように設けられている。   Further, the control circuit 7 controls the speed and the like when moving the transfer stage 3 on which the glass substrate 30 is placed in the direction of arrow B. The transport stage 3 is provided with guides 3 a for arranging the glass substrate 30 obliquely with respect to the moving direction of the transport stage 3 so as to support the four sides of the glass substrate 30.

このような液滴吐出装置１を用いて配向膜溶液６をガラス基板３０上に塗布する手順を図２を用いて説明する。図示されるように、インクジェットヘッド２に対して例えば４５°傾斜させて配置されたガラス基板３０上を、インクジェットヘッド２が矢印Ｃに示す方向に相対的に移動しながら、各ノズル２ａから液滴６ａが吐出される。このとき各ノズル２ａの吐出は、それぞれのノズル２ａがガラス基板３０の吐出エリア３５内に入った際に吐出を開始するように制御回路７により制御されている。したがって、図示されるように、先ず中央のノズル２ａから吐出を開始し、その後、順に左右のノズル２ａ，２ａ，２ａ，・・・が吐出を開始するようになっている。   The procedure for applying the alignment film solution 6 onto the glass substrate 30 using such a droplet discharge device 1 will be described with reference to FIG. As shown in the figure, droplets are ejected from each nozzle 2a while the inkjet head 2 relatively moves in a direction indicated by an arrow C on a glass substrate 30 that is inclined at 45 ° with respect to the inkjet head 2, for example. 6a is discharged. At this time, the discharge of each nozzle 2 a is controlled by the control circuit 7 so that the discharge is started when each nozzle 2 a enters the discharge area 35 of the glass substrate 30. Therefore, as shown in the drawing, first, the discharge is started from the central nozzle 2a, and then the left and right nozzles 2a, 2a, 2a,.

このように滴下された液滴６ａは着弾の瞬間にガラス基板３０上で濡れ広がり、隣接する液滴６ａ同士が接触すると、その接触位置からそれらの液滴６ａ同士が繋がって一体となり、単一の薄膜が形成され、そして乾燥などの所定の工程を経ると、ガラス基板３０上に配向膜３２が形成される。   The droplets 6a dripped in this way wet and spread on the glass substrate 30 at the moment of landing, and when the adjacent droplets 6a come into contact with each other, the droplets 6a are connected to each other from the contact position and become a single unit. Then, after a predetermined process such as drying, an alignment film 32 is formed on the glass substrate 30.

図２に示すように、インクジェットヘッド２がガラス基板３０に対して相対的に移動する方向Ｃがガラス基板３０の絵素の配列方向Ｘ，Ｙに対して所定角度傾斜されていることにより、配向膜の膜厚が不均一に形成される方向と、ガラス基板に構成される絵素の配列方向とが一致しない構成になっている。したがって、従来技術で説明したような配向膜の膜厚が不均一に形成される方向と、ガラス基板に構成される絵素の配列方向とが一致しないことによる干渉等が原因で生じる表示ムラ等の発生を抑制することができる。   As shown in FIG. 2, the direction C in which the inkjet head 2 moves relative to the glass substrate 30 is inclined by a predetermined angle with respect to the arrangement directions X and Y of the picture elements of the glass substrate 30. The direction in which the film thickness is formed non-uniformly and the arrangement direction of the picture elements formed on the glass substrate do not coincide with each other. Therefore, display unevenness caused by interference caused by the alignment direction of the alignment film as described in the prior art and the arrangement direction of the pixels formed on the glass substrate do not match. Can be suppressed.

以上、本発明の一実施形態について説明したが、本発明はこうした実施形態に何ら限定されるものではなく、本発明の要旨を逸脱しない範囲において、種々なる態様で実施できることは勿論である。例えば、上記実施の形態ではカラーフィルター側基板に適用した例を示したが、勿論ＴＦＴアレイ側基板にも適用できることは言うまでもない。   As mentioned above, although one Embodiment of this invention was described, this invention is not limited to such Embodiment at all, Of course, in the range which does not deviate from the summary of this invention, it can implement in a various aspect. For example, in the above embodiment, an example is shown in which the present invention is applied to the color filter side substrate, but it goes without saying that the present invention can also be applied to the TFT array side substrate.
