著色層形成用敏輻射線性組成物Coloring layer forming sensitive radiation linear composition

本發明係關於著色層形成用敏輻射線性組成物，濾色片及彩色液晶顯示裝置，更詳言之，係關於透過型或反射型之彩色液晶裝置，彩色成像(imaging)管元件等所使用之濾色片之製造所使用之敏輻射線性組成物，由該敏輻射線性組成物所形成之濾色片，以及具備該濾色片之彩色液晶顯示元件。The present invention relates to a linear composition for sensitive radiation formation of a colored layer, a color filter and a color liquid crystal display device, and more particularly, to a transmissive or reflective type color liquid crystal device, a color imaging tube element, and the like. A linear composition of a sensitive radiation used for the manufacture of the color filter, a color filter formed of the linear composition of the sensitive radiation, and a color liquid crystal display element having the color filter.

作為使用著色敏輻射線性組成物而形成濾色片之方法，係在基板上或預先形成了所望圖型之遮光層之基板上，形成著色敏輻射線組成物之塗膜，透過具有設定圖型之光罩照射放射線(以下，稱為「曝光」)，進行顯影將未曝光部溶解除去，其後藉由事後烘烤，獲得各色像素之方法(例如，專利文獻1及專利文獻2)為周知。As a method of forming a color filter using a coloring sensitive radiation linear composition, a coating film of a color-sensitive radiation composition is formed on a substrate or a substrate on which a light-shielding layer of a desired pattern is formed in advance, and has a setting pattern The method of irradiating radiation (hereinafter referred to as "exposure"), developing and unmasking the unexposed portion, and then obtaining the pixels of each color by post-baking (for example, Patent Document 1 and Patent Document 2) is known. .

在具備此種濾色片之液晶顯示元件可求得高亮度化，因此就濾色片近年對高度光透過率之要求則日益高漲。In the liquid crystal display element having such a color filter, high luminance can be obtained, and thus the demand for high light transmittance of the color filter in recent years is increasing.

又，在目前，伴隨數位攝影相機或高畫質電視等之普及，可重現在冬天如大海之深藍色或真紅色的夕陽，色濃度再現性之高度彩色液晶顯示元件為所求。為了提高色濃度之再現性，黑色顯示部之「黑色」可清晰的顯現，影像之輪廓可清楚呈現之，具有更高對比之像素為必要。In addition, with the spread of digital cameras or high-definition televisions, it is possible to reproduce the dark blue or true red sunset of the sea in winter, and the high-color liquid crystal display element of color density reproducibility is sought. In order to improve the reproducibility of the color density, the "black" of the black display portion can be clearly displayed, and the outline of the image can be clearly presented, and it is necessary to have a higher contrast pixel.

因此，具有高度光透過率及對比之像素開發被強烈企 望。Therefore, the development of pixels with high light transmittance and contrast is strongly hope.

在綠色之像素，係含有綠色顏料或者綠色與黃色之顏料，其對光透過率或對比有產生極大影響已為周知。習知在綠色顏料主為使用C.I.色素綠7及C.I.色素綠36(含有銅作為中心金屬之鹵化酞菁化合物)。但是，自含該等顏料之著色敏輻射線性組成物所得像素之光透過率及對比並非臻至充分之等級，在可提供更高畫質之畫面之觀點尚無法滿足。In green pixels, it is known that it contains green pigments or green and yellow pigments, which have a great influence on light transmittance or contrast. It is known that green pigments mainly use C.I. Pigment Green 7 and C.I. Pigment Green 36 (halogenated phthalocyanine compounds containing copper as a central metal). However, the light transmittance and contrast of the pixels obtained from the linear composition of the color-sensitive radiation containing the pigments are not sufficient, and the viewpoint of providing a higher-quality picture cannot be satisfied.

-(1)步驟-- (1) Step -

首先，在基板表面上，可因應需要，將形成像素之部分予以劃分之方式形成遮光層，在此基板上，例如將含有綠色(A)顏料之本發明濾色片用敏輻射線性組成物以通常作為液狀組成物之塗佈中，進行預烘烤使溶劑蒸發，來 形成塗膜。在此步驟所使用之基板方面，例如除了玻璃，矽，聚碳酸酯，聚酯，芳香族聚醯胺，聚醯胺醯亞胺，聚醯亞胺，聚醚碸之外，有環狀烯烴之開環聚合物或其氫化物等。First, on the surface of the substrate, a light-shielding layer may be formed by dividing the portion forming the pixel as needed, and on the substrate, for example, the color filter of the present invention containing the green (A) pigment is used as the linear composition of the sensitive radiation. Usually, as a coating of a liquid composition, prebaking is performed to evaporate the solvent. A coating film is formed. In terms of the substrate used in this step, for example, in addition to glass, ruthenium, polycarbonate, polyester, aromatic polyamine, polyamidimide, polyimine, polyether oxime, cyclic olefin a ring-opening polymer or a hydride thereof or the like.

又，在該等基板，可依照所期望，作矽烷偶合劑等所致藥品處理，電漿處理，離子電鍍，濺鍍，氣相反應法，真空蒸鍍等適宜之前處理準備。Further, these substrates can be prepared as appropriate for the treatment of chemicals such as decane coupling agents, plasma treatment, ion plating, sputtering, gas phase reaction, vacuum vapor deposition, etc., as desired.

在將液狀組成物塗佈於基板之際，可採用使用到旋轉塗佈法，流鑄(flow casting)塗佈法，輥塗佈法，縫模塗佈機之塗佈法等適宜之塗佈法，而以使用旋轉塗佈法，縫模塗佈機之塗佈法為佳。When the liquid composition is applied to the substrate, a suitable coating such as a spin coating method, a flow casting coating method, a roll coating method, or a slit coater coating method may be employed. The coating method is preferably a coating method using a spin coater using a spin coating method.

預烘烤之條件通常在70~110℃為2~4分左右。The prebaking conditions are usually about 2 to 4 minutes at 70 to 110 °C.

塗佈厚度，作為溶劑除去後之膜厚，通常為1.0~10μm，較佳為1.0~6.0μm，特佳為1.0~4.0μm。The coating thickness and the film thickness after removal as a solvent are usually 1.0 to 10 μm, preferably 1.0 to 6.0 μm, and particularly preferably 1.0 to 4.0 μm.

在使用於曝光之放射線方面，例如，可使用可視光線，紫外線，遠紫外線，電子束，X線等，以波長在190~450nm範圍之放射線為佳。For the radiation to be used for exposure, for example, visible light, ultraviolet light, far ultraviolet light, electron beam, X-ray or the like can be used, and radiation having a wavelength in the range of 190 to 450 nm is preferable.

放射線之曝光量，通常為10~10,000J/m2 。The exposure amount of radiation is usually 10 to 10,000 J/m 2 .

其後，可使用顯影液，較佳為鹼顯影液進行顯影，將塗膜之未曝光部溶解除去。Thereafter, development may be carried out using a developing solution, preferably an alkali developing solution, to dissolve and remove the unexposed portion of the coating film.

該鹼顯影液方面，以例如碳酸鈉，氫氧化鈉，氫氧化鉀，氫氧化四甲基銨，膽鹼，1,8-二氮雜二環-[5.4.0]-7-十一烯，1,5-二氮雜二環-[4.3.0]-5-壬烯等之水溶液為佳。In terms of the alkali developer, for example, sodium carbonate, sodium hydroxide, potassium hydroxide, tetramethylammonium hydroxide, choline, 1,8-diazabicyclo-[5.4.0]-7-undecene An aqueous solution of 1,5-diazabicyclo-[4.3.0]-5-nonene or the like is preferred.

Further, using the sensitive radiation linear composition of the color filter of the present invention containing a green (A) pigment, the green pixel can be obtained by repeating the steps (1) to (4). The pattern is formed on the same substrate, and then the blue sensitive radiation linear composition containing red and blue pigments is used, and the steps (1) to (4) are repeated to make the red and blue pixel patterns on the same substrate. Formed, the pixel pattern of the three primary colors of green, red and blue can be formed on the substrate in a set arrangement of pixel arrays. However, the order in which the pixel patterns of the respective colors are formed can be arbitrarily selected.
