Abstract

Provided are a photosensitive resin composition for a color filter and a color filter using the same. The photosensitive resin composition for a color filter includes (A) a colorant including a diaminopyridine azo-based dye including a structure represented by Chemical Formula 1, and showing an absorption wavelength at 450 to 550nm, (B) an acryl-based binder resin, (C) an acryl-based photopolymerizable monomer, (D) a photopolymerization initiator, and (E) a solvent.

Description

technical field [0001] The present disclosure relates to a photosensitive resin composition for a color filter and a color filter using the composition. Background technique [0002] The liquid crystal display device is one of the display devices, and has the advantages of lightness, thinness, low cost, low power consumption, and excellent integration with integrated circuits. Therefore, it is widely used in notebook computers, monitors, and TV screens. The liquid crystal display device includes a lower substrate and an upper substrate. The lower substrate includes a black matrix, a color filter, and an indium tin oxide (ITO) pixel electrode. The upper substrate includes an active circuit portion including a liquid crystal layer, a thin film transistor, an electrical storage Capacitor layer, and ITO pixel electrode. In a liquid crystal display device, a color filter is formed by sequentially laminating a plurality of color filters (generally, formed of three primary colors ...
