The present invention relates to a method and a member for creating a device.
図１は携帯電話の表示部の一例を示したものである。図１（ａ）に示される携帯電話の表示パネル１００は、表示部である内枠部１と、表示部の外側の外枠部２とで構成されている。また、図１（ｂ）に示される携帯電話の表示パネル１０１の外枠部には例えば携帯電話会社を表すミラー文字３が施されている場合もある。 FIG. 1 shows an example of a display unit of a mobile phone. A display panel 100 of a mobile phone shown in FIG. 1A includes an inner frame portion 1 that is a display portion, and an outer frame portion 2 outside the display portion. Further, the outer frame portion of the display panel 101 of the mobile phone shown in FIG. 1B may be provided with a mirror character 3 representing a mobile phone company, for example.
表示パネルの基本的構成について図面により説明する。図２（ａ）は上記携帯電話の表示パネル１００の断面の一部を模式的に示す図で、図２（ｂ）は上記携帯電話の表示パネル１０１の断面の一部を模式的に示す図である。 A basic configuration of the display panel will be described with reference to the drawings. 2A is a diagram schematically showing a part of the cross section of the display panel 100 of the mobile phone, and FIG. 2B is a diagram schematically showing a part of the cross section of the display panel 101 of the mobile phone. It is.
図２（ａ）に示される表示パネル１００は、表示パネル基材４の裏面にインキ層６と接着層７が、また表面にはハードコート層８が設けられており、最上面には保護フィルム９が貼られている。 The display panel 100 shown in FIG. 2A is provided with an ink layer 6 and an adhesive layer 7 on the back surface of the display panel substrate 4, and a hard coat layer 8 on the surface, and a protective film on the top surface. 9 is affixed.
図２（ｂ）に示される表示パネル１０１は、表示パネル基材４の裏面にはミラー文字を施したミラー印刷層５と、インキ層６と、接着層７とが、また表面にはハードコート層８が設けられており、最上面には保護フィルム９が貼られている。 The display panel 101 shown in FIG. 2B has a mirror printing layer 5 with a mirror character on the back surface of the display panel substrate 4, an ink layer 6, and an adhesive layer 7, and a hard coat on the surface. The layer 8 is provided and the protective film 9 is stuck on the uppermost surface.
表示パネル基材４として、ガラスシート、ＰＭＭＡ（ポリメタクリル酸メチル樹脂）シート、ＰＣ（ポリカーボネート）シート等のいずれかが用いられる。 As the display panel substrate 4, any one of a glass sheet, a PMMA (polymethyl methacrylate resin) sheet, a PC (polycarbonate) sheet, and the like is used.
ミラー印刷層５、インキ層６は一般的にはシルクスクリーン印刷によって形成されている。このインキ層６は表示パネルの意匠性を持たせるために隠蔽性や美粧性を有した層となっている。 The mirror printing layer 5 and the ink layer 6 are generally formed by silk screen printing. The ink layer 6 is a layer having a concealing property and a cosmetic property in order to give the design properties of the display panel.
図２に示される従来用いられている表示パネルでは、ミラー印刷層５は５〜７μｍで、インキ層６は隠蔽性を確保するためにスクリーン印刷を数回まで重ねて加飾印刷する場合が多く、数μｍ〜２５μｍ程度にまで厚くなる。 In the conventionally used display panel shown in FIG. 2, the mirror printing layer 5 is 5 to 7 μm, and the ink layer 6 is often subjected to decorative printing by repeating screen printing several times to ensure concealment. The thickness is increased to about several μm to 25 μm.
そのため、表示部である内枠部１（以下、表示部）と、表示部の外側の外枠部２と段差は、図２（ａ）で示すミラー印刷層５のない表示パネルの場合は数μｍ〜２５μｍとなり、図２（ｂ）で示すミラー印刷層５を有する表示パネルの場合は１０〜３０μｍ程度にまでなり、図３に示すように接着層７（層厚：数μｍ程度）を塗布しても、段差は埋めきれず（図３（ａ））、更にその下部にタッチパネル電極層１０やＲＧＢ表示層１１を設ける場合や（図３（ｂ））や、タッチパネル機能のない表示パネルの場合にはＲＧＢ表示層１１を設けるが（図３（ｃ））、この場合に段差が原因となって表示部に気泡を抱き込んでしまい、不良品が発生してしまう問題がある。 Therefore, the inner frame portion 1 (hereinafter referred to as the display portion) which is the display portion and the outer frame portion 2 outside the display portion and the steps are several in the case of the display panel without the mirror print layer 5 shown in FIG. In the case of a display panel having the mirror printing layer 5 shown in FIG. 2B, the thickness is about 10 to 30 μm, and an adhesive layer 7 (layer thickness: about several μm) is applied as shown in FIG. However, the step cannot be filled (FIG. 3 (a)), and the touch panel electrode layer 10 and the RGB display layer 11 are provided in the lower part (FIG. 3 (b)), or the display panel having no touch panel function. In this case, the RGB display layer 11 is provided (FIG. 3 (c)). In this case, there is a problem that air bubbles are embraced in the display portion due to a step and a defective product is generated.
そこで本発明では、表示部の外側の外枠部２を表示部１と段差のない方法で形成した液晶表示パネル用部材の作成方法及び液晶表示パネル用部材を提供することを目的とする。 Accordingly, an object of the present invention is to provide a method for producing a liquid crystal display panel member and a liquid crystal display panel member in which the outer frame portion 2 outside the display portion is formed by a method having no step difference from the display portion 1.

以下、図面を参照して本発明に係る液晶表示パネル用部材の作成方法及び液晶表示パネル用部材を実施するための形態を説明する。 DESCRIPTION OF EMBODIMENTS Hereinafter, a method for producing a liquid crystal display panel member and a liquid crystal display panel member according to the present invention will be described with reference to the drawings.
図４は本発明による液晶表示パネル用部材１１０を作成する方法を説明するための図である。表示パネル用部材１１０は、ガラスシート、ＰＭＭＡシート、ＰＣシートのいずれかを用いたパネル基材１４に蒸着層２６−１、接着層１７、ハードコート層１８が設けられており、また最上面には保護フィルム１９が貼られている。 FIG. 4 is a view for explaining a method of producing the liquid crystal display panel member 110 according to the present invention. In the display panel member 110, a vapor deposition layer 26-1, an adhesive layer 17, and a hard coat layer 18 are provided on a panel base material 14 using any one of a glass sheet, a PMMA sheet, and a PC sheet, and on the uppermost surface. The protective film 19 is affixed.
（実施例１）
本発明に係る蒸着層２６−１は、先ず、パネル基材１４に表示部をマスキングして、隠蔽を考慮した黒蒸着（例えばクロム蒸着）によって第一の蒸着層２６−１を加飾形成して外枠部を得る（図４（ａ））。隠蔽性が足りない場合は、第二蒸着層またはインクジェット層２６−２を加飾形成する（図４（ｂ））。この場合の第二蒸着層またはインクジェット層２６−２は、第一の蒸着層と同等又は同等以下の極薄加飾層である。
Example 1
First, the vapor deposition layer 26-1 according to the present invention masks the display portion on the panel base 14 and decorates and forms the first vapor deposition layer 26-1 by black vapor deposition (for example, chromium vapor deposition) in consideration of concealment. To obtain an outer frame (FIG. 4A). When the concealability is insufficient, the second vapor-deposited layer or the inkjet layer 26-2 is decorated and formed (FIG. 4B). In this case, the second vapor-deposited layer or the inkjet layer 26-2 is an ultra-thin decorative layer that is equal to or less than or equal to the first vapor-deposited layer.
次に、マスキングを剥離し、その後、接着材ＯＣＡ（光学接着剤）を塗布しＵＶ硬化を行って接着層１７を形成する（図４（ｃ））。 Next, the masking is peeled off, and then an adhesive OCA (optical adhesive) is applied and UV curing is performed to form the adhesive layer 17 (FIG. 4C).
図５（ａ）は（図４（ｃ））を上面から見た図で、この場合、マスキングされた表示部３０の外枠部３１の内端３２は鋸歯状のザラツキが見られる（図５（ｂ））。このザラツキは、意匠性を悪くするため、以下に述べるレーザーによる微細加工を施す。 FIG. 5A is a top view of FIG. 4C. In this case, the inner end 32 of the outer frame portion 31 of the masked display portion 30 has saw-toothed roughness (FIG. 5). (B)). In order to deteriorate the designability, this roughness is subjected to fine processing by laser as described below.
そこで、近紫外レーザー、遠紫外レーザー、超短パルスレーザーなどのレーザー光線を外枠部３１の内端３２に沿って照射し、黒蒸着を溶かして内端３２をザラツキのない内端３２ａに仕上げる（図５（ｃ））。 Therefore, a laser beam such as a near-ultraviolet laser, a far-ultraviolet laser, or an ultrashort pulse laser is irradiated along the inner end 32 of the outer frame portion 31 to melt the black deposition and finish the inner end 32 to an inner end 32a without roughness ( FIG. 5 (c)).
上記レーザー加工によれば、（図５（ｄ））に示すザラツキの大きさ（山谷のピーク高さの範囲Ｐを指す）はサンプル数ｎ＝３で、蒸着直後が４３２μｍであったのに対して、レーザー加工後は２２５μｍと滑らかになり、レーザー加工による効果が認められ、美粧性に優れた外枠が得られた。 According to the above laser processing, the roughness (showing the peak height range P of the valley) shown in (FIG. 5 (d)) was n = 3 and 432 μm immediately after the deposition. After the laser processing, it became as smooth as 225 μm, the effect of laser processing was recognized, and an outer frame excellent in cosmetics was obtained.
また、上記第一の蒸着層２６−１は、２４２０〜３３３０Å程度であり、第二の蒸着層またはインクジェット層２６−２は第一の蒸着層と同等、又はより薄いため、ＵＶ硬化ＯＣＡ接着剤（厚み：数μｍ）をその後全面塗布しても、パネル基材１４の裏面の表示部と外枠部との厚み段差が生じることはない。 Moreover, since the said 1st vapor deposition layer 26-1 is about 2420-3330 mm, and the 2nd vapor deposition layer or the inkjet layer 26-2 is equivalent to a 1st vapor deposition layer, or thinner, UV hardening OCA adhesive agent Even if (thickness: several μm) is subsequently applied to the entire surface, a thickness step between the display portion and the outer frame portion on the back surface of the panel substrate 14 does not occur.
従来のスクリーン印刷によって得られた外枠部を備えた液晶表示用部材と上記方法によって得られた外枠部を備えた液晶表示用部材の０．５ｍｍΦ以上の気泡の抱き込み不良の発生回数を比較した結果、サンプル数ｎ＝１０に対して従来のスクリーン印刷によって得られた外枠部を備えた液晶表示用部材が５回であったのに対して、上記方法によって得られた外枠部を備えた液晶表示用部材の場合には２回であり、不良発生の頻度が少ないことが認められた。 The number of occurrences of defective inclusion of bubbles of 0.5 mmΦ or more in a liquid crystal display member having an outer frame part obtained by conventional screen printing and a liquid crystal display member having an outer frame part obtained by the above method As a result of comparison, the number of samples n = 10 was 5 times for the liquid crystal display member having the outer frame portion obtained by conventional screen printing, whereas the outer frame portion obtained by the above method was used. In the case of the liquid crystal display member provided with the number of times, it was confirmed that the frequency of defects was small.
（実施例２）
上記では、第一の蒸着層２６−１、更に第二の蒸着層２６−２をマスクを用いて形成したが、図６に示すように、ガラスシート、ＰＭＭＡシート、ＰＣシートのいずれかを用いたパネル基材１４の裏面に蒸着層３６を設けた（図６（ａ））後、蒸着層３６の全面にフォトレジスト膜を３７を塗布し（図６（ｂ））、次に表示枠に相当するフォトマスク３８を介して露光した後（図６（ｃ））、現像（図６（ｄ））、レジスト膜３７を剥離（図６（ｅ））することによって外枠を作成しても良い。この場合の外枠の内端はザラツキのないものが得られ、上記レーザー加工を必要としない。
(Example 2)
In the above, the first vapor deposition layer 26-1 and the second vapor deposition layer 26-2 were formed using a mask, but as shown in FIG. 6, any one of a glass sheet, a PMMA sheet, and a PC sheet was used. After the vapor deposition layer 36 was provided on the back surface of the panel substrate 14 (FIG. 6A), a photoresist film 37 was applied to the entire surface of the vapor deposition layer 36 (FIG. 6B), and then the display frame was formed. Even after exposure through the corresponding photomask 38 (FIG. 6C), development (FIG. 6D), and peeling off the resist film 37 (FIG. 6E), an outer frame can be formed. good. In this case, the inner edge of the outer frame is free from roughness, and the laser processing is not required.
尚、上記説明ではクロム蒸着によって黒色に加飾形成する外枠部を例示したが、これに限定されず、蒸着膜の設計を行い、蒸着の材料種類や膜厚や層数を決めることによって、有色でしかも美粧性、隠蔽性に優れた外枠部を加飾形成することが出来る。 In the above description, the outer frame portion that is decorated in black by chromium vapor deposition is exemplified, but the present invention is not limited to this, by designing the vapor deposition film, and by determining the material type, film thickness, and number of layers for vapor deposition, It is possible to decorate and form an outer frame portion that is colored and excellent in cosmetics and concealment.
また、蒸着による外枠部の形成であるので図７に示すような外枠部３１に形成された例えばアイコン部４０を有する静電容量のタッチパネルにおいて、容易にタッチレスポンスを得ることが出来る。 Further, since the outer frame portion is formed by vapor deposition, a touch response can be easily obtained in a capacitive touch panel having, for example, the icon portion 40 formed on the outer frame portion 31 as shown in FIG.
このようにして、段差のない隠蔽性、美粧性に優れた蒸着加飾パネルを得ることが出来る。 In this way, it is possible to obtain a vapor-deposited decorative panel excellent in concealability and cosmetics without steps.
以上のように本発明による液晶表示パネル用部材の作成方法によれば、隠蔽性、美粧性の高い液晶表示パネル用部材が得られる。また、パネル基材の裏面に形成される表示部と外枠部との段差は、従来に比べて格段に小さくなり、パネルに加工する際の歩留まり向上が可能となる。 As described above, according to the method for producing a member for a liquid crystal display panel according to the present invention, a member for a liquid crystal display panel having high concealability and cosmetics can be obtained. Further, the step between the display portion and the outer frame portion formed on the back surface of the panel base material is remarkably smaller than the conventional case, and the yield when processing into a panel can be improved.
