【発明が解決しようとする課題】液晶表示素子上に透明タッチスイッチを配置した場合、透明タッチスイッチの表面および透明タッチスイッチと表示素子との間の面で外からの光が反射するため画質が悪くなった。 [SUMMARY OF THE INVENTION When placing the transparent touch switches on the liquid crystal display device, the image quality because the light is reflected from the outside in terms between the surface and the transparent touch switch and the display device of the transparent touch switch It became worse. 特に反射型の液晶表示素子にタッチスイッチを載せた場合に画面が暗くなってしまい、画質が著しく悪かった。 Would particularly dark screen when carrying the touch switch in the reflection type liquid crystal display element, the image quality was significantly poor.

【0004】 [0004]

【課題を解決するための手段】上記課題を解決するために、透明フイルムや透明基板を使用したアナログ抵抗膜方式、デジタル抵抗膜方式、静電容量または超音波方式などの透明タッチスイッチと液晶表示素子を備えた表示装置において、液晶表示素子の表示面と透明タッチスイッチの入力領域の裏面を、透明接着剤で接着する構成とした。 In order to solve the above problems SUMMARY OF THE INVENTION, analog resistive film type using a transparent film or a transparent substrate, a digital resistive film type, a transparent touch switch and a liquid crystal display such as a capacitive or ultrasonic type in the display device having the element, the back surface of the input area of ​​the display surface and the transparent touch switch of the liquid crystal display device was configured to adhere a transparent adhesive. この構成によりタッチスイッチと液晶表示素子間の反射率が従来より低下するので画質が向上する。 Reflectance between touch switch and a liquid crystal display device by this arrangement is the image quality is improved because the lower than conventional.

【0005】さらに、前記透明接着剤に透明フィラーを混入することとした。 Furthermore, it was decided to incorporate a transparent filler on the transparent adhesive. これにより、入力領域等の大きな面積で接着させた場合に、透明接着剤の硬化収縮により発生する表示ムラを画質を損なうことなく抑えることができる。 Thus, when adhered with a large area such as the input area, the display unevenness caused by cure shrinkage of the transparent adhesive can be suppressed without impairing the image quality.

【0006】また、その製造方法においては、透明タッチスイッチの裏面の中央に透明接着剤を塗布する工程と、前記タッチスイッチを反転し、表示装置を位置あわせする工程と、タッチスイッチを反転することにより塗布された透明接着剤に発生する液ダレを、液晶表示素子にゆっくり接着させて重ね合わせる工程と、前記透明接着剤をタッチスイッチと液晶表示素子の間を流動させる工程と、を備えることとした。 [0006] in the manufacturing method, the steps of applying a transparent adhesive to the center of the rear surface of the transparent touch switch inverts the touch switch, to reverse the step of aligning the display device, the touch switch and providing the liquid dripping generated at the coated transparent adhesive, and a step of superimposing and slowly adhering to the liquid crystal display device, and a step of flowing between the touch switch and a liquid crystal display device of the transparent adhesive by did. この製造方法により、透明接着剤を大気中で気泡の進入なくタッチスイッチと液晶表示素子の間に充填できる。 This manufacturing method, the transparent adhesive can be filled between the entrance without touch switch and a liquid crystal display device of the bubble in the air.

【0007】さらに、透明タッチスイッチが少なくともその入力領域面で透明接着剤により面接着された表示素子と、前記タッチスイッチに加わる力を吸収する機構を有する入力ペンとを備えることとした。 Furthermore, transparent touch switch and further comprising an input pen having a mechanism for absorbing the display element surface-bonded by a transparent adhesive at least in the input region surface, the force applied to the touch switch. このような入力ペンにより、タッチスイッチに加わる力が一定値以上大きくならないので、表示ムラが発生することがない。 Such input pen, the force applied to the touch switch does not increase above a certain value, never display unevenness occurs. 上記のように構成された表示装置は、画質が向上した。 A display device configured above, the image quality is improved. また、高価な製造装置を必要せず、簡単に製造することが可能となった。 Also, without requiring an expensive manufacturing apparatus, it has become possible to easily manufacture.

【0008】 [0008]

【発明の実施の形態】透明タッチスイッチを有する表示装置において、少なくとも入力領域全面のタッチスイッチと液晶表示素子との間に、タッチスイッチおよび液晶表示素子の基板材料と等しい屈折率を持つ接着剤を充填する。 In the display device having a transparent touch switch PREFERRED EMBODIMENTS, between the touch switch and a liquid crystal display device of at least the input area the entire surface, the adhesive having a substrate material equal refractive index of the touch switch and a liquid crystal display device to fill. これによりタッチスイッチ、接着剤層、液晶表示素子の屈折率が同等になり、各層間での光の屈折がなくなるので、タッチスイッチと液晶表示素子との間の反射がほぼなくなり、画質が向上する。 Thus touch switch, the adhesive layer, an equivalent refractive index of the liquid crystal display device, since the refraction of light in the layers is eliminated, the reflection between the touch switch and a liquid crystal display device is eliminated substantially, image quality is improved .

【0009】 [0009]

【実施例】以下に本発明の実施例を図面に基づいて説明する。 EXAMPLES be described with reference to the embodiment of the present invention accompanying drawings. (実施例1)図1は本発明による表示装置の第1の実施例を示す概略側面図である。 (Example 1) FIG. 1 is a schematic side view showing a first embodiment of a display device according to the present invention. 本実施例による表示装置は、0.7mmの2枚のガラス製透明基板1aと1bの間に液晶層が形成、保持され、偏向板2aと反射板付き偏向板2bがそれぞれの透明基板に貼り付けられている。 The display device according to the present embodiment, the liquid crystal layer is formed between the two sheets of transparent glass substrates 1a and 1b of 0.7 mm, is held, deflecting plate 2a and the reflector with deflector plate 2b is attached to each of the transparent substrate It is attached. また、液晶を駆動するためのドライバIC3が透明基板の端子部に実装されている。 The driver IC3 for driving the liquid crystal is mounted on the terminal portion of the transparent substrate. その液晶表示素子の表示面側に0.7mmのガラスとフイルムを使用したアナログ抵抗膜方式のタッチスイッチ4が透明接着剤5により接着してある。 Its touch switch 4 analog resistance film type using the display surface side of the liquid crystal display device of 0.7mm glass and the film of are bonded with a transparent adhesive 5. 透明接着剤は少なくともタッチスイッチの入力領域の裏面全体に充填している。 Transparent adhesives are filled the entire back surface of the input area at least touch switch. ここで、硬化後の屈折率が1.47〜1.57の透明接着剤を用いると、ガラス基板の屈折率1.52とほぼ等しいため、タッチスイッチと液晶表示素子間の反射がほぼなくなり画質が向上する。 Here, the refractive index after curing a transparent adhesive from 1.47 to 1.57, for substantially equal to the refractive index 1.52 of the glass substrate, the touch switch and substantially eliminates image quality reflection between the liquid crystal display device There is improved.

【0010】さらに、硬化後の屈折率がガラスの屈折率1.52と等しい透明接着剤を用いるのが最適である。 Furthermore, the refractive index after curing is optimal to use a equal transparent adhesive refractive index of 1.52 of glass.
すなわち、タッチスイッチが接着されるガラスと接着剤の硬化後の屈折率が同一であるため、タッチスイッチと液晶表示素子間の反射がなくなり極めて画質が向上する。 That is, since the refractive index after curing of the glass and the adhesive touch switch is adhered is the same, the reflection between the touch switch and a liquid crystal display device is eliminated very improved picture quality. ここで用いられるタッチスイッチは、アナログ抵抗膜方式に限らず、抵抗膜デジタル方式、静電容量方式または、超音波方式でもよい。 Touch switches used herein is not limited to analog resistive film type, a resistive digital type, a capacitive type, or may be an ultrasonic method.

【0011】(実施例2)図2は本願発明による表示装置の第2の実施例である。 [0011] (Embodiment 2) FIG. 2 is a second embodiment of the display device according to the present invention. その基本的な構成は、実施例1と同一である。 Its basic configuration is the same as in Example 1. タッチスイッチと液晶表示素子を接着する透明接着剤5の硬化収縮率は5%程度あるため、該接着剤が硬化するとタッチスイッチと液晶表示素子が反り、表示画面にムラが発生する恐れがある。 Since the cure shrinkage of the transparent adhesive 5 to bond the touch switch and a liquid crystal display device is about 5%, touch switch and a liquid crystal display element is warped when the adhesive is cured, there is a possibility that unevenness occurs on the display screen. そこで、透明接着剤5に透明フィラー6を混ぜ、硬化収縮率を低くすることで反りの発生を防止する。 Therefore, mixing a transparent filler 6 to the transparent adhesive 5, to prevent the occurrence of warpage by lowering the cure shrinkage.

【0012】本実施例の透明フィラーは真球形プラスチック粒子であり、その直径は12ミクロン、屈折率は1.47〜1.57である。 [0012] Transparent filler of the present embodiment is a true spherical plastic particles, a diameter of 12 microns and a refractive index of 1.47 to 1.57. すなわち、接着剤の硬化後の屈折率に近い屈折率を持つ透明フィラーを用いるのがよい。 That is, it is preferable to use a transparent filler with a refractive index close to the refractive index after curing of the adhesive.

【0013】さらに、透明フィラーの混入量は、接着剤に対し2wt%とした。 Furthermore, contamination of the transparent filler, was 2 wt% relative to the adhesive. これ以上混ぜた場合は、接着剤層が曇ってしまうので画質が低下する。 If mixed more, the picture quality is lowered because thereby cloudy adhesive layer. ただし、フィラーと接着剤の屈折率がほぼ同じ場合(例えば1.52) However, if substantially the refractive index of the filler and the adhesive same (e.g. 1.52)
は、接着剤層の曇りが低下するので、更に多く混ぜることが可能である。 Since haze decreases the adhesive layer, it is possible to mix more.

【0014】(実施例3)図3は、本発明によるタッチパネルを有する表示装置の製造方法を示す実施例である。 [0014] (Embodiment 3) FIG. 3 is an example that illustrates a method of manufacturing a display device having a touch panel according to the present invention. 図4にそのフロー図を示す。 Figure 4 shows the flow diagram. まず図3(A)の様に、透明タッチスイッチの裏面に透明接着剤を塗布する。 First, as in FIG. 3 (A), applying a transparent adhesive to the back surface of the transparent touch switches. 必要に応じて脱泡した透明接着剤を用いてもよい。 It may be used transparent adhesives defoaming as needed.
例えばこの透明接着剤は紫外線硬化型であり、約6インチの液晶表示素子の場合に塗布する量は約1.4gである。 For example, the transparent adhesive is UV-curable, the amount to be applied to the case of the liquid crystal display device of about 6 inches is about 1.4 g.

【0015】次に、この透明タッチスイッチを反転して、液晶表示素子11と位置合わせを行う。 Next, by inverting the transparent touch switch, to align the liquid crystal display device 11. この時、図3(B)のように、透明タッチスイッチに塗布された接着剤に液だれ5aができる。 At this time, as shown in FIG. 3 (B), the can dripping 5a to the applied to the transparent touch switch adhesive. この液だれ5aは、塗布量と接着剤の粘度により発生の仕方が変わる。 The dripping 5a varies how generated by the viscosity of the coating amount with the adhesive. したがって、塗布量と接着剤の粘度を調節することにより液だれを制御することができる。 Therefore, it is possible to control the liquid dripping by adjusting the viscosity of the coating weight and the adhesive. 生じさせる液だれは1つでも複数でも構わない。 Cause dripping may be one or more.

【0016】この状態で、図3(C)のようにタッチパネルを液晶表示素子11とゆっくり重ね合わせる。 [0016] In this state, slowly superimposing the liquid crystal display device 11 with a touch panel as shown in FIG. 3 (C). 液だれの先端と液晶表示素子の表面が接触する瞬間の状態は、限りなく点に近くなるため、気泡は混入しない。 Instantaneous state where the surface of the dripping of the tip and the liquid crystal display element are in contact, to become closer to a point as possible, air bubbles are not mixed.

【0017】しかしながら、このスピードが早い場合、 [0017] However, if the speed is fast,
液だれの先端に衝撃が加わり、図5のように液だれの表面に波(凹凸)が発生し、この部分に気泡が混入することとなる。 Joined by impact dripping tip, the wave (unevenness) occurs on the dripping of the surface as shown in FIG. 5, the bubble in this portion is being mixed. 液だれと液晶表示素子が接触するときのスピードは、約50μm/s以下が好ましい。 Speed ​​when dripping the liquid crystal display element are in contact is preferably equal to or less than about 50 [mu] m / s. 重ね合わせは、タッチパネルと液晶表示素子の距離が約0.5mm Superposition, the distance of the touch panel and the liquid crystal display element is approximately 0.5mm
のスペースを保持した状態で、タッチパネルをフリーの状態にする。 While holding the space, the touch panel in a free state.

【0018】この状態のまま約10〜30分放置すると、接着剤はゆっくりと透明タッチスイッチと液晶表示素子の間に流れて両間隙に充填する。 [0018] When left about 10-30 minutes in this state, the adhesive is filled into both gaps flows between the slowly transparent touch switch and a liquid crystal display device. このように、放置により接着剤が充填するために、接着剤の粘度は100 Thus, since the adhesive agent is filled with standing, the viscosity of the adhesive 100
0〜6000cpの範囲が好ましい。 Range of 0~6000cp is preferred. 接着剤が充填したのを確認して、紫外線を上面から均一に照射して硬化する。 After confirming that the adhesive is filled and hardened uniformly irradiated with ultraviolet rays from above. 以上の工程により、接着層の厚みは0.1〜0.2 Through the above process, the thickness of the adhesive layer is 0.1 to 0.2
mmとなり、従来より0.4〜0.8mm薄くなる。 mm next, 0.4~0.8mm thinner than conventional. このようにして、透明タッチスイッチと液晶表示素子の間に接着剤が充填される。 Thus, the adhesive between the transparent touch switch and a liquid crystal display device is filled.

【0019】また、接着剤の粘度が高い場合、例えば1 Further, when the high viscosity of the adhesive, for example 1
0000cpの接着剤の場合は、タッチスイッチと表示素子の間に広がらず、両間隙内を充填することはできない。 For adhesive 0000Cp, not spread between the touch switch and the display device, it is impossible to fill in both gaps. しかしながら、加温することにより接着剤の粘度が低下するので、重ね合わせ後に加温放置すれば、200 However, since the viscosity of the adhesive is decreased by warming, if warmed left after superposition, 200
00cp程度の粘度があっても充填させることができる。 Even if the viscosity of approximately 00cp can be filled.

【0020】接着剤は、紫外線硬化型に限らず、可視光硬化型でも硬化するときに発ガスがほとんど無い物であればよく、2液のエポキシ接着剤でもよい。 [0020] The adhesive is not limited to the ultraviolet curing, as long as there is little gas emission when curing in the visible light curable, may be two-liquid epoxy adhesive. ただし、加温処理が必要なほど高粘度の熱硬化型の接着剤は、加温放置工程で硬化が促進するため使用することはできない。 However, the adhesive of thermosetting high viscosity enough to warrant heating process can not be used for curing is promoted by warming standing process.

【0021】ここで、接着剤は、タッチパネル面だけではなく、液晶表示素子面にも塗布しておいても構わない。 [0021] Here, the adhesive is not only a touch panel surface, it may be previously also applied to the liquid crystal display device surface. ただし、気泡の混入を防ぐため、液晶表示素子面には薄く均一に塗布しておく必要がある。 However, in order to prevent the inclusion of air bubbles, it is necessary to thinly and uniformly applied to the liquid crystal display device surface.

【0022】また、透明接着剤を塗布する側は、液晶表示素子だけでもよい。 Further, the side to be coated with a transparent adhesive, or only the liquid crystal display device. このとき、紫外線硬化型の透明接着剤を使用して、重ね合わせたとき下側となるタッチスイッチ側から紫外線を照射する場合は、石英ガラス等の透明台の上で貼り合わせを行い、透明接着剤が充填してから石英ガラスごしに紫外線を照射する。 At this time, by using the transparent adhesive of the ultraviolet curable, if irradiated with ultraviolet light from the touch switch side to be lower when superimposed performs bonding on a transparent base such as quartz glass, transparent adhesive agent is irradiated with ultraviolet light quartz glass over after filling.

【0023】(実施例4)図6は本発明によるタッチスイッチ付表示装置を有する電子装置の実施例で、タッチスイッチ面をペンで入力することにより液晶表示画面に生じる表示むらを、専用ペンを使用することで防止する。 [0023] Example (Example 4) Figure 6 is an electronic device having a display device with a touch switch according to the present invention, the display unevenness occurring in the liquid crystal display screen by inputting a touch switch surface with a pen, a dedicated pen It is prevented by use. すなわち、透明タッチスイッチと液晶表示素子を透明接着剤で面接着した表示装置にペン等を用いて入力する電子装置において、約200〜300g以上の力がペン先よりタッチスイッチに加わると、接着剤を介して働く力により液晶表示装置の画面に表示むらが発生する恐れがある。 That is, in an electronic device for inputting with a pen or the like to a transparent touch switch and a liquid crystal display device was surface-bonded with a transparent adhesive display device, when about 200~300g more force is applied to the touch switch from the pen tip, the adhesive there is a risk that display unevenness on the screen of the liquid crystal display device is produced by the force acting through. そこで、表示むらが発生する200g以上の力を吸収する機構、つまり、タッチスイッチに200g Therefore, the mechanism for absorbing the 200g or more of the force display unevenness occurs, in other words, to touch the switch 200g
以上の力が加わらない機構を有するペンを用いることとした。 It decided to use the pen having a mechanism not inject excessive force.

【0024】すなわち、この専用ペン7はペン先8に2 [0024] In other words, this dedicated pen 7 is in the pen tip 8 2
00g以上の力で収縮するばね9が内臓された構造である。 Spring 9 which shrinks by a force more than 00g is built structure. このペンによれば液晶表示素子に200g以上の力が加わらないため、表示装置の画質を損なうことなくペン入力が可能となる。 According to this pen for a liquid crystal display device not inject more force 200 g, it is possible to pen input without impairing the image quality of the display device. ペンの構造は特にこれに限定するものではない。 The structure of the pen is not particularly limited thereto.

【0025】さらに、アナログ抵抗膜方式のタッチスイッチの作動力は15〜100gなので、100g以上の力で収縮するばねが内臓された構造の専用ペンを用いて100g以上の力がタッチスイッチに加わらないように構成しても、スイッチの動作に支障がないとともに、液晶表示装置の画質を損なわない電子装置が実現できる。 Furthermore, the actuating force of the touch switch of the analog resistive film type since 15 to 100, the force of more than 100g is not applied to the touch switch by using a dedicated pen having a structure spring is built to contract at a force greater than 100g be configured such, with no trouble in the operation of the switch, an electronic device that does not impair the image quality of the liquid crystal display device can be realized.

【0026】 [0026]

【発明の効果】本発明によれば、以上説明したように透明タッチスイッチを備えた表示装置の画質が向上し、また、薄型化も可能となった。 According to the present invention, image quality is improved in the display device having a transparent touch switch as described above, also became possible thinner. 更に、面接着することで全体的な強度が向上した。 Furthermore, it improved overall strength by surface-bonded. 高価な設備投資がいらないため安価に表示装置を提供できるようになった。 Expensive capital investment is now able to provide a low cost display device because it does not need.
