Description

47364 A7 B7 V. Description of the invention (Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs, developed and developed with excellent development strength. _ __ A / t »nsL Filter, light sheet dispersion method, blue and green are divided into pigments The light resistance is mainstream. The effect of 10 ~ 60% of this hair is lower than the photoresist of semiconductor photoresist. The low cost of the above photoresist includes: multiple organs, solvents and past properties are insufficient. In terms of the sensitivity and dense sensitivity of the Ming system, there are four methods, three, and three. The primary dispersion method and the heat resistance method can be polymerized by light irradiation, and then the basic resin composition. Specifically, it is related to a Based on production cost and quality considerations, dyeing, printing, and electronic color filters are commonly used in the production of color filters on glass substrates. Organic pigments, color filters made at each pixel, have high precision, so 'currently, it has become a color filter solution with a hardened film for color and color The inside of the red. The solid content of the photosensitive resin composition described in the preferred and preferred manufacturing method accounts for the pigment that absorbs and scatters the UV light source used during exposure. Therefore, the photosensitive resin composition of the present invention is sensitive to UV light. The positive photoresist used in the transmission is far lower. For the above reasons, pigment dispersion must use a high-sensitivity photoreaction system; the most representative system is acrylic radical polymerization type photosensitive resin composed of acrylic acid. The radical polymerizable photosensitive resin composition is negative. It has high sensitivity, good material stability, design diversity, and advantages. It is the most widely used material at present. Its ingredients include energy-based monomers and pigments. , Photosensitive initiators, organic binder additives, etc. The pigment-dispersed photoresist used, because the ratio between the light-transmitting components of the red pigment is not well controlled, and the proper initiator is not selected, so it cannot take into account the development Properties, adhesion, and development chromatic aberration.
