本發明是關於一種視窗基板及含此之觸控螢幕面板,具備:視窗基板;及非傳導性遮光圖案,形成於前述視窗基板的一面的非顯示部,其中前述非傳導性遮光圖案具備:凹凸圖案,包含珍珠顏料;色相圖案層,覆蓋前述凹凸圖案形成平坦表面;及前述色相圖案層上部的遮光層,藉此,可具備能表現優良立體感及視認性圖案的非顯示部,更適用於大面積的基板。 在本發明中,立體感是指除了以三維結構視認者,也包含從正面及斜面視認的形狀確認差異的概念。 以下參照圖式來詳細說明本發明。但是,本說明書所附以下圖式,是例示本發明的較佳實施例,與前述發明內容一起,用來更容易地理解本發明的技術思想,所以本發明並非僅以前述圖式所記載事項來限定並解析者。 <視窗基板> 在第2圖表示本發明的具備非傳導性遮光圖案200的視窗基板100的概略垂直剖面圖。 關於本發明的非傳導性遮光圖案200具備:凹凸圖案210、色相圖案層220及遮光層230。 凹凸圖案210包含珍珠顏料,且是由在視窗基板100的視認側的相反側表面突出形態的凹凸結構所形成,藉由在非傳導性遮光圖案200中形成紋理結構,在非傳導性遮光圖案200中提供立體結構。閃耀的珍珠顏料以凹凸圖案形成,由於與後述的色相圖案層220的反射率及折射率的差異,可顯著提升立體感及質感效果。目的圖案是以凹凸圖案210的具體形態所形成。 凹凸圖案210的高度較佳為2~20μm。若為前述數值範圍,則可同時確保優良視認性及工程性。 凹凸圖案210所包含的珍珠顏料是多重色相的珍珠光澤顏料,統稱表示珍珠色、虹色、金屬色等顏料。用於本發明的珍珠顏料,不僅美感優良,反射率高,立體感及質感的具體展現性能也優良。 用於本發明的珍珠顏料,也可以具備:塗佈反射層核心部及前述核心部的高折射率層。前述反射核心部及高折射率層的具體材料可依目的色相、反射率等來進行各種選擇。 做為反射層核心部為列舉例如雲母(mica)、絹雲母(sericite)、滑石(talc)、高嶺土(kaolin)、矽礬石類黏土礦物(smectite clay

用於本發明的珍珠顏料的平均粒徑,較佳為5~15μm。 當使用具有前述數值範圍的平均粒徑的珍珠顏料時,組成物的保存穩定性高,改善硬化用光線的遮蔽問題,有助於形成良好圖案。若平均粒徑未滿5μm,則視認性(光特性或珍珠感)會降低,若超過15μm,則在塗佈組成物時會塞住噴嘴,或塗佈面的均勻性降低,會有不易形成圖案的情況。 關於本發明的珍珠顏料,相對於凹凸圖案210的總重量,包含0.2~2重量%的量。若含量未滿0.2重量%,則視認性(光特性或珍珠感)會降低,若超過2重量%,則工程性會降低。 凹凸圖案210對應需要,除了前述珍珠顏料以外,也可以更包含在本發明範圍內該領域所知的著色劑,例如染料或顏料。 色相圖案層220是覆蓋凹凸圖案210的層,從視認側來看時,由於因具體展現凹凸圖案210的凹凸結構的紋理圖案導致入射光的反射及折射與色相圖案層220的反射現象,具有將立體感及質感賦予因凹凸圖案210產生的圖案的功能。 色相圖案層220為了具體展現想要的色相,由複數個著色層組成,在此情況下,各層可具有彼此不同的色相。例如,藉由形成複數個具有彼此不同色相的層,也可具體展現混色的色相。 色相圖案層220是以可進行光微影技術的非傳導性色相圖案形成用組成物所形成,關於這點將後述。 遮光層230藉由在色相圖案層220形成平坦表面,可使之後的接著過程容易進行,來保護以金屬配線等的遮蔽及色相圖案層220覆蓋的凹凸圖案210,具有在非傳導性遮光圖案具體展現目的色相的功能。故可具有與色相圖案層220相同色相,或具有不同色相。較佳為為了在金屬配線等的遮蔽效果及色相圖案層220的色相效果的具體展現,也可以是黑色色相層。 遮光層230的厚度較佳為1~10μm。若厚度未滿1μm,遮蔽性會降低,當超過10μm,工程性會降低。 如前述的具有非傳導性遮光圖案的本發明的視窗基板,可具備具有立體感,優良視認性的圖案的非顯示部。 <視窗基板的製造方法> 以下,更詳細地說明本發明的視窗基板的製造方法。在第3圖概略地表示本發明的製造方法的一具體例。

The non-conductive light-shielding pattern 200 of the present invention includes a concave-convex pattern 210, a hue pattern layer 220, and a light-shielding layer 230. The concave-convex pattern 210 includes a pearl pigment and is formed of a concave-convex structure that protrudes on the opposite side surface of the viewing side of the window substrate 100, and the non-conductive light-shielding pattern 200 is formed by forming a texture structure in the non-conductive light-shielding pattern 200. Provides a three-dimensional structure. The glittering pearl pigment is formed in a concave-convex pattern, and the difference in reflectance and refractive index from the hue pattern layer 220 to be described later can significantly improve the three-dimensional effect and the texture effect. The target pattern is formed in a specific form of the concave-convex pattern 210. The height of the concavo-convex pattern 210 is preferably 2 to 20 μm. If it is the above numerical range, it is possible to ensure excellent visibility and engineering at the same time. The pearl pigment contained in the concavo-convex pattern 210 is a multi-ply pearl luster pigment, and collectively refers to a pigment such as pearl color, rainbow color, or metallic color. The pearl pigment used in the present invention is excellent not only in aesthetics, but also in high reflectance, and also in specific expression properties of three-dimensional feeling and texture. The pearl pigment used in the present invention may further include a high refractive index layer that coats the core portion of the reflective layer and the core portion. The specific material of the reflective core portion and the high refractive index layer can be variously selected depending on the intended hue, reflectance, and the like.

The pearl pigment used in the present invention has an average particle diameter of preferably 5 to 15 μm. When a pearl pigment having an average particle diameter in the above numerical range is used, the composition has high storage stability, improves the shielding problem of light for curing, and contributes to formation of a good pattern. When the average particle diameter is less than 5 μm, the visibility (light characteristics or pearly feeling) is lowered. When the average particle diameter is less than 15 μm, the nozzle is blocked when the composition is applied, or the uniformity of the coated surface is lowered, and it is difficult to form.

The concavo-convex pattern 210 is correspondingly required, and in addition to the aforementioned pearl pigment, a coloring agent known in the art such as a dye or a pigment may be further included in the scope of the present invention. The hue pattern layer 220 is a layer covering the concavo-convex pattern 210, and when viewed from the viewing side, the reflection and refraction of incident light and the reflection phenomenon of the hue pattern layer 220 due to the texture pattern of the concavo-convex structure specifically exhibiting the concavo-convex pattern 210 have The stereoscopic effect and the texture give the function of the pattern generated by the concave-convex pattern 210. The hue pattern layer 220 is composed of a plurality of colored layers in order to specifically exhibit a desired hue, in which case the layers may have different hue from each other. For example, by forming a plurality of layers having different hue from each other, the hue of the mixed color can also be specifically exhibited. The hue pattern layer 220 is formed of a composition for forming a non-conductive hue pattern capable of performing photolithography, and will be described later.

The function of showing the hue of the purpose. Therefore, it may have the same hue as the hue pattern layer 220, or have a different hue. It is preferable to use a black hue layer for the purpose of shielding the metal wiring or the like and the hue effect of the hue pattern layer 220. The thickness of the light shielding layer 230 is preferably from 1 to 10 μm. If the thickness is less than 1 μm, the shielding property is lowered, and when it exceeds 10 μm, the workability is lowered. The window substrate of the present invention having the non-conductive light-shielding pattern as described above can be provided with a non-display portion having a three-dimensional appearance and a pattern having excellent visibility. <Method of Manufacturing Window Substrate> Hereinafter, a method of manufacturing the window substrate of the present invention will be described in more detail.

The alkali-soluble binder resin, the photopolymerizable compound, the photopolymerization initiator, and the solvent of the composition for forming a non-conductive hue pattern can be used in the same composition and content as the composition for forming a concave-convex pattern. The description is omitted. After coating and hardening the composition for forming a non-conductive hue pattern, the hue pattern layer 220 can be left only in the target portion of the non-display portion by photolithography. The hue pattern layer may be composed of a plurality of colored layers as needed. By having a plurality of colored layers, more hue can be specifically presented to enhance the shielding effect of the metal wiring. From this side, the hue pattern layer formed by a plurality of colored layers may have different hue of each layer. Correspondingly, the photolithography of the hue pattern layer 220 is performed simultaneously with the photolithography for forming the light shielding layer 230 to be described later, and can be performed in one step. Next, a composition for forming a non-conductive light-shielding layer is applied to the hue pattern layer 220, and the light-shielding layer 230 is formed by photolithography. The light-shielding layer 230 is a composition for forming a non-conductive light-shielding layer in the same field as the composition for forming a non-conductive hue pattern used in the hue pattern layer 220, and can be formed by the same photolithography. As a preferred example, as shown in FIG. 3, the light shielding layer 230 may be formed of a black hue layer for the shielding effect of the metal wiring and the clear hue expression of the lower colored light shielding layer 230. Thus, the non-conductive light-shielding pattern of the present invention formed by vapor deposition and photolithography can specifically exhibit a film structure. The window substrate of the present invention can be combined with a structure commonly used in the art to form a touch screen panel. For example, the sensing pattern may be formed on a window substrate on which the non-conductive pattern is formed, and the metal wiring may be connected to the circuit to form a corresponding region on the non-display portion, and a printed circuit board or the like. , connected to the electrode pattern. The sensing pattern is used to sense the static electricity generated by the human body when the finger touches the display portion of the contact area of the image sensor, and connect the electrical signal. The conductive material for forming the sensing pattern is not particularly limited, and is, for example, indium tin oxide (ITO), indium zinc oxide (IZO), zinc oxide (ZnO), indium tin zinc oxide (IZTO), or cadmium tin oxide ( CTO), PEDOT (poly(3,4-ethylenedioxythiophene)), carbon nanotubes (CNT) and metal wires. These may be used alone or in combination of two or more. The metal used for the metal wire is not particularly limited, and examples thereof include gold (Ag), silver, aluminum, copper, iron, nickel, titanium, ruthenium, chromium, and the like. These may be used alone or in combination of two or more. The metal wiring is used to transmit an electrical signal generated from the sensing pattern via contact of the window substrate display portion to the FPCB, ICChip, or the like. The protective film is used to protect the sensing pattern and the metal wiring from scattering when the window substrate is broken. The material of the protective film is not particularly limited as long as it provides durability and is transparent, and may be, for example, PET (polyethylene terephthalate). As the printed circuit board, various types of printed circuit boards can be used, but for example, a flexible printed circuit board (FPCE) can be used. The touch screen panel of the present invention can be usefully used in combination with a pixel display device such as a liquid crystal display, an OLEC, or an elastic display through an additional process known in the art.
