Development of high sensitivity - High optical density resin black matrix for color TFT LCD

Target1 Resin black matrix (RBM) is necessary properties of high sensitivity, thin film and straightness. To improve productivity of RBM, we developed high sensitivity RBM available at exposure energy of 40mJ/cm(2). Low. thickness RBM development must be accomplished with optical density (OD) value. OD 4.5/1um was prepared for Carbon Black (CB) size reduce and functional dispersant addition. Straightness of RBM was to increase flow property of pattern at oven, we implemented adjustment of binder polymer and dispersant.
