Description

200804975 (1) Description of the Invention [Technical Field] The present invention relates to a radiation-sensitive composition for forming a color layer, a method of forming a color layer, a color filter, and a color liquid crystal display device. More specifically, it relates to a radiation-sensitive composition for forming a color layer for manufacturing a color filter in a transmissive or reflective type color liquid crystal display or a color image pickup device, and forms a color from the radiation-sensitive composition. The square Φ method of the layer includes a color filter of a color layer formed by the radiation-sensitive composition, and a color liquid crystal display device including a color filter. [Prior Art] In order to manufacture a color filter using a radiation-sensitive composition for forming a color layer, there is known a method for producing a color pixel by using a substrate or a substrate A coating film for forming a radiation-sensitive composition of a color layer is formed on a substrate of the light-shielding layer to be patterned, and the coating film is exposed to radiation through a mask having a desired pattern (hereinafter referred to as "exposure") The exposed coating film is developed to dissolve and remove the unexposed portion, and the developed coating film is subjected to post-baking in a clean oven or a hot plate (see JP-A 2-144 5 02 and JP-A 3- 5 3 20 1 ) (" JP-A" as used herein means "a Japanese patent application filed without prior disclosure"). When the color filter is produced in this manner, the radiation-sensitive composition for forming the color layer is usually applied to the substrate by spin coating. As the size of the substrate is getting larger, the coating technique is shifting to a slit and a spin-and-spin coating or a spinless coating. 200804975 (2) Since the slit nozzle is used in the slit and spin coating method and the non-rotation coating method, the coatability and yield problems are caused by the use of the slit nozzle. That is, since the slit nozzle is inevitably contaminated by the radiation-sensitive composition for forming the color layer, the step of cleaning the slit nozzle becomes necessary. In this cleaning step, the slit nozzle is typically cleaned with a primary solvent used to form the radiation sensitive composition of the colored layer. However, when the radiation-sensitive composition for forming a color layer has low solubility in the main solution φ agent, it forms a convex hole at the nozzle portion, thereby causing the following problem, when it is applied to the substrate. The streak is formed in the traveling direction of the nozzle, and the dried product of the radiation-sensitive composition for forming the colored layer may fall and adhere to the substrate to become a defect, resulting in a decrease in yield. Therefore, the solvent resolubility of the dried product of the radiation-sensitive composition for forming a colored layer is an important factor. Although the formation of the dried product can be suppressed by adding a high boiling point solvent to the radiation sensitive composition for forming the colored layer, the high boiling point solvent is difficult to completely evaporate, thereby causing gelation or lengthening the vacuum baking time, thereby reducing the yield. . Depending on the type and amount of the high-boiling solvent selected, it causes problems in the vacuum baking step after coating the radiation-sensitive composition for forming a colored layer, which is contained in the composition. The fine bubbles float to the surface of the coating film during evaporation of the solvent, and are dried as crater-like defects (hereinafter referred to as "bulk holes"). The purpose of the present invention is to provide a color layer for forming. Radiation Sensitivity Group-6 - 200804975 (3) A product which solves the above problems and hardly produces a convex hole, and the dried product of the composition formed in the slit nozzle has high solvent resolubility. Another object is to provide a method of forming a color layer from the above-described radiation-sensitive composition of the present invention. A further object of the present invention is to provide a color filter having a color layer formed of the above-described radiation-sensitive composition of the present invention, and A liquid crystal display device including the color filter. φ Other objects and advantages of the present invention will become apparent from the following description.
