黑矩陣用顏料分散組成物及含有此黑矩陣用顏料分散組成物之黑矩陣用顏料分散光阻組成物Pigment dispersion composition for black matrix and pigment dispersion resist composition for black matrix containing pigment dispersion composition for black matrix

本發明係有關於一種使用在液晶面板黑矩陣形成之黑矩陣用顏料分散組成物以及含有此黑矩陣用顏料分散組成物之黑矩陣用顏料分散光阻組成物。The present invention relates to a pigment dispersion composition for a black matrix formed using a black matrix of a liquid crystal panel, and a pigment dispersion resist composition for a black matrix containing the pigment dispersion composition for a black matrix.

液晶顯示方式多使用於電腦、彩色電視、手機及攝影機等之影像顯示元件上。液晶影像顯示元件係利用形成有各色畫素之彩色濾光片及具有光閘作用之液晶,來將影像於畫面上。The liquid crystal display mode is mostly used on image display elements such as computers, color televisions, mobile phones, and video cameras. The liquid crystal image display element uses a color filter in which respective color pixels are formed and a liquid crystal having a shutter function to image the image on the screen.

其次,彩色濾光片通常是先在玻璃、塑膠片等透明基板的表面上,形成具有條狀(strip)或馬賽克狀(mosaic)等之開口部的黑色矩陣(黑矩陣,black matrix),接著,再依序於開口部上形成紅、綠、藍等3種以上不同顏色之畫素,而完成者。Next, the color filter is usually formed on a surface of a transparent substrate such as a glass or a plastic sheet to form a black matrix (black matrix) having a strip or a mosaic or the like. Then, three or more different color pixels of red, green, and blue are formed on the opening in order, and are completed.

在此處,黑矩陣的功能是控制各顏色間的混合及藉由防止漏光而達到提升對比的效果。因此,基於高遮光性的要求,過去薄膜皆使用遮光性高之鉻等蒸鍍膜。然而,由於其形成步驟複雜且價格高等理由,近來已改為使用含有顏料及感光性樹脂之顯影成像法(Photolithography,顏料法)。Here, the function of the black matrix is to control the mixing between the colors and to achieve the effect of improving the contrast by preventing light leakage. Therefore, in the past, the film has been used as a vapor deposition film such as chromium having a high light-shielding property. However, development imaging methods (photolithography) containing a pigment and a photosensitive resin have recently been used instead due to the complicated formation steps and high cost.

上述的顏料法,係將碳黑等之黑色顏料或數種顏料以調成黑色之方式來組合使用之。In the above pigment method, a black pigment such as carbon black or a plurality of pigments are used in combination to form a black color.

進而,為了得到高遮光性,勢必要大大提高顏料本身的含量,然而當顏料濃度愈高時,顯影性、解析度、密著性、穩定性等之其他必要特性會降低,而對遮光性之提高造成限制。另一方面,就形成彩色濾光片之皮膜而言,亦被要求薄膜化,在顏料必須以高濃度來因應的狀況下,更加助長導致了分散穩定性及流動性降低之結果。Further, in order to obtain high light-shielding property, it is necessary to greatly increase the content of the pigment itself. However, when the pigment concentration is higher, other necessary characteristics such as developability, resolution, adhesion, stability, and the like are lowered, and the light-shielding property is lowered. Increase the restrictions. On the other hand, in the case of forming a film of a color filter, film formation is required, and in the case where the pigment must be applied at a high concentration, the dispersion stability and fluidity are further promoted.

因此,為了解決上述問題,遂有以下方案被提出:使用了比表面積110m2 /g以下、pH為2~9之碳黑,以及由具有鹼性官能基之聚酯或聚醚所構成的高分子分散劑而組成之感光性樹脂(例如,特開平10-082908號公報);使用了平均一次粒子徑20~30nm、DBP吸油量140ml/100 g以下、pH為2.5~4之碳黑,以及胺值1~100mgKOH/g的有機化合物系分散劑所組成之碳黑分散液(例如,特開2004-292672號公報)。如上所述般的顏料分散物,具有即使是在高顏料濃度下,分散穩定性、流動性皆非常良好之特徵。Therefore, in order to solve the above problems, the following scheme has been proposed: a carbon black having a specific surface area of 110 m 2 /g or less, a pH of 2 to 9, and a polyester composed of a polyester or a polyether having a basic functional group are used. A photosensitive resin composed of a molecular dispersing agent (for example, JP-A-10-082908); carbon black having an average primary particle diameter of 20 to 30 nm, a DBP oil absorption of 140 ml/100 g or less, and a pH of 2.5 to 4, and A carbon black dispersion liquid composed of an organic compound-based dispersant having an amine value of 1 to 100 mgKOH/g (for example, JP-A-2004-292672). The pigment dispersion as described above has a feature that dispersion stability and fluidity are excellent even at a high pigment concentration.

然而,近來在彩色液晶顯示裝置中,色彩鮮明度與銷售量的增加幅度成正比關係,故市場對於提升色彩鮮明度之期待也非常地強烈。因此,對於肇因於彩色濾光片或黑矩陣圖案之形成不良,而導致了色漏等會損及色彩鮮明度之成因,已變成非常重大的研究課題。However, recently, in color liquid crystal display devices, the color sharpness is directly proportional to the increase in sales volume, so the market is also very strong in anticipation for improving color vividness. Therefore, it has become a very important research topic for the formation of color filters or black matrix patterns, which causes color leakage and the like to cause color sharpness.

就以顯影成像法來形成黑矩陣而言,首先,係將黑矩陣用光阻組成物塗佈於基板上。之後,再藉由具有既定圖案之光罩以紫外線進行曝光,並使曝光部的塗膜硬化。接著,利用顯影液去除未曝光部份之塗膜,就形成出如同上述既定圖案之黑矩陣。此時,為了得到良好的圖案,就必須要求光阻組成物具有良好的圖案再現性。例如,在顯影終了時,必須達到在未曝光部份中沒有顯影殘渣,曝光部具有足夠的細線再現性,以及能形成出銳利的邊緣之圖案等。In order to form a black matrix by a development imaging method, first, a black matrix photoresist composition is applied onto a substrate. Thereafter, the film is exposed to ultraviolet light by a mask having a predetermined pattern, and the coating film of the exposed portion is cured. Next, the coating film of the unexposed portion is removed by the developer to form a black matrix like the predetermined pattern described above. At this time, in order to obtain a good pattern, it is necessary to require the photoresist composition to have good pattern reproducibility. For example, at the end of development, it is necessary to achieve no development residue in the unexposed portion, the exposed portion has sufficient fine line reproducibility, and a pattern which can form a sharp edge or the like.

然而,作為黑矩陣,不只遮光性很高,對於紫外線之遮光性也高。因此,在曝光部份中,即使塗膜表面已硬化,靠近基板之邊緣仍會因紫外線無法到達,而呈現未硬化前的原狀態。然後,未硬化的殘餘部分就會被顯影液慢慢地侵蝕而變細,最終導致曝光部份也被全部去除,而產生黑矩陣消失之現象。However, as a black matrix, not only the light-shielding property is high, but also the light-shielding property with respect to ultraviolet rays is high. Therefore, in the exposed portion, even if the surface of the coating film is hardened, the edge near the substrate is still unreachable by the ultraviolet rays, and the original state before the hardening is exhibited. Then, the unhardened residual portion is gradually eroded and thinned by the developer, and finally the exposed portion is also completely removed, and the black matrix disappears.

從完全地去除如上所述般的未曝光部,到曝光部變細而無法得到符合當作黑矩陣之規定機能間的時間長度,稱為『顯影寬容度(margin)』(Development Latitude)。此顯影寬容度較少者,由於未曝光部份去除後,馬上會造成曝光部變細或消失,因此很難弄清楚停止顯影的時機點。特別是前述的已高顏料濃度化之光阻組成物,因其在曝光部中之未硬化比例容易變高,所以無法取得足夠的顯影寬容度。因此,會產生未曝光部無法完全地被去除,曝光部變細而無法得到符合規定之機能等在工程管理層面而言非常大的問題。The "exposure Latitude" is called "developing latitude" from the fact that the unexposed portion as described above is completely removed, and the exposure portion is thinned so that the length of time between the functions defined as the black matrix cannot be obtained. In this case where the development latitude is small, since the exposed portion is thinned or disappeared immediately after the unexposed portion is removed, it is difficult to ascertain the timing of stopping the development. In particular, the above-described photoresist composition having a high pigment concentration tends to be high in the unhardened ratio in the exposed portion, so that sufficient development latitude cannot be obtained. Therefore, there is a problem in that the unexposed portion cannot be completely removed, and the exposure portion is thinned, and it is impossible to obtain a function that meets the prescribed performance, which is extremely large at the engineering management level.

在此處,本發明之課題係提供一種遮光性良好、且顯影寬容度大的黑矩陣用顏料分散組成物及含有此黑矩陣用顏料分散組成物之黑矩陣用顏料分散光阻組成物。An object of the present invention is to provide a pigment dispersion composition for a black matrix having good light-shielding properties and a large development latitude, and a pigment dispersion resist composition for a black matrix containing the pigment dispersion composition for a black matrix.
