Field of the Invention The present invention relates to a radiation sensitive composition for forming a green image, a color filter, and a color liquid crystal display device, and more particularly, to a suitable a radiation sensitive composition for producing a color filter in a transmissive or reflective color liquid crystal device, a color image sensor device, or the like; a color filter formed of the radiation sensitive composition; and the color filter Color liquid crystal display elements.先前 [Prior Art] As a method of forming a color filter using a coloring sensitizing radiation composition, there is known a method of forming a color-sensing radiation combination on a substrate or a substrate on which a light-shielding layer of a desired pattern is formed in advance The coating film of the object is irradiated with radiation (hereinafter referred to as "exposure") through a mask having a predetermined pattern, developed, dissolved and removed, and then post-baked, thereby obtaining pixels of respective colors (for example, refer to Patent Document 1. Patent Document 2). ^ The liquid crystal display element having the above color filter requires an enlargement of a high luminance and a color reproduction area, and therefore, a color filter is required to have higher transmittance and higher color purity in recent years. Regarding a green pixel, a pigment composition containing a polyhalogenated zinc phthalocyanine pigment is known as a material for providing a color filter having a high luminance and a large color reproduction area, and has been attracting attention (for example, see Patent Document 3). However, the pigment composition containing a polyhalogenated zinc phthalocyanine pigment has poor dispersion stability, and thus foreign matter is likely to be generated, which is difficult to apply to mass production. On the other hand, in the field of the color filter technology in recent years, the size of the substrate used in the formation of the color filter of the 200941139 is becoming larger, and at the same time, the reduction of the exposure amount and the shortening of the tact time have become mainstream. Therefore, it is required that the coloring-sensing radiation composition does not cause pattern defect or peeling when developing at a low exposure amount, that is, high sensitivity is required. Based on the above background, there is an urgent need to develop a radiation-sensitive composition which can form a green pixel having high luminance, is excellent in dispersion stability, and has high sensitivity. Patent Document 1: Japanese Laid-Open Patent Publication No. Hei No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. A high-green pixel, excellent dispersion stability, and high sensitivity, a radiation-sensitive composition for forming green pixels. Still another object of the present invention is to provide a color filter including a pixel formed of the above-described radiation sensitive composition for forming a green φ pixel, and a color liquid crystal display element including the color filter. The inventors conducted intensive studies and unexpectedly discovered that the above problem can be solved by combining a polybromide zinc phthalocyanine pigment CI Pigment Green 58 with a specific radiation-sensitive polymerization initiator and containing it in a radiation-sensitive composition. Having completed the present invention, that is, the present invention provides a radiation sensitive composition for forming a green pixel, which composition contains (A) a colorant, (B) an alkali-soluble resin, (C) a polyfunctional monomer, and D) a radiation-sensitive polymerization initiator, wherein (A) the coloring 200941139 agent contains CI Pigment Green 58, and the (D) radiation-sensitive polymerization initiator contains a compound represented by the following formula (1): 〇R1
