Abstract

The invention discloses a colored photosensitive resin composition, a color filter and a display device. The colored photosensitive resin composition contains (A) a colorant, (B) an alkali-soluble resin, (C) a photopolymerizable compound, (D) a thermosetting resin represented by Chemical Formula 1, (E) a carbazole-based photoinitiator agent, and (F) solvent, wherein, (A) the colorant includes a pigment including at least two red pigments selected from the group consisting of Pigment Red 177, Pigment Red 179, and Pigment Red 208, and also includes At least one of the group consisting of carbon black and a porphyrazine-based compound, and (E) the carbazole-based photoinitiator includes a compound represented by Chemical Formula 2.

Description

technical field [0001] The present invention relates to a colored photosensitive resin composition, a color filter produced using the composition, and a display device including the color filter. Background technique [0002] Color filters are widely used in various display devices such as imaging devices, liquid crystal displays (LCDs), and the like, and their application fields are rapidly expanding. A color filter for an imaging device or LCD is composed of three coloring patterns including red, green, and blue or three coloring patterns including yellow, magenta, and cyan. [0003] Each colored pattern of a color filter is generally formed using a colored photosensitive resin composition including a colorant such as a pigment or a dye, an alkali-soluble resin, a photopolymerizable compound, a photoinitiator, and a solvent. Formation of a colored pattern using a colored photosensitive resin composition is generally performed by photolithography. [0004] Colored photose...
