RESIN BLACK MATRIX, LIGHT BLOCKING PHOTOSENSITIVE RESIN COMPOSITION, TFT ELEMENT SUBSTRATE AND LIQUID CRYSTAL DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a highly reliable resin black matrix which has sufficient light blocking characteristics, suppresses temperature rise due to heat generated by a TFT element and does not have failures of a TFT element substrate and fluctuation in liquid crystal drive.

SOLUTION: The maximum light transmittance of the resin black matrix in a wavelength range of 400 nm to 700 nm is permitted to be not more than 1%, and the average light transmittance in a wavelength range of 850 nm to 3,000 nm to be not less than 60%. Alternatively, the minimum light transmittance is permitted to be not less than 50%.
