The present invention provides a method characterized in that it contains at least a pigment, a pigment dispersant, a binder, a photopolymerizable compound, and a photopolymerization initiator, at least one of the pigments is a compound represented by the following general formula, and the pigment dispersant A green photosensitive resin composition in which at least one amino group-containing compound is used, a photosensitive transfer material produced using the composition, a color filter substrate using the material, and a display device equipped with the color filter substrate. (In the formula, M represents a specified metal atom. X 1 ~X 16 Any 8-16 positions in the formula are represented by halogen atoms, and the rest are represented by hydrogen atoms. Y represents a fluorine atom, a chlorine atom, a bromine atom, an iodine atom or an oxygen atom, and m represents an integer of 0 to 2).

Description

technical field [0001] The present invention relates to a color filter substrate that can be preferably used in large-screen liquid crystal display devices such as notebook personal computers and television monitors, a green photosensitive resin composition that can be used in the color filter substrate, and a photosensitive converter. A printing material and a display device including the color filter substrate. Background technique [0002] A color filter is an indispensable component in a liquid crystal display (hereinafter also referred to as a "liquid crystal display device"). The liquid crystal display is very compact, and its performance is also higher than that of the current CRT display, and it is replacing the CRT display. [0003] In forming a color image of a liquid crystal display, light passing through a color filter is directly colored into the color of each pixel constituting the color filter, and the light of these colors is combined to form a color image. ...
