Description

[Technical Field] The present invention relates to a photosensitive resin composition containing a polycarboxylic acid resin, a polyphenolic resin as a binder polymer, and a cured product thereof. In particular, it is a photosensitive resin composition which is used for a color filter resin composition for a color filter, a protective film for color filter, a distance meter for color filter, and an interlayer insulating film for color filter. [Prior Art] A color-sensitive photosensitive resin composition containing an alkali-soluble resin, a pigment, and a photopolymerization initiator is widely used for producing a color filter plate which constitutes a component such as a color liquid crystal display device or a color solid-state imaging device. A method of producing a color filter using the colored photosensitive resin composition is known, for example, by forming a layer (1) (Fig. 1) composed of a colored photosensitive resin composition on the surface of a substrate (2), The layer (1) is a method of irradiating the light (4) by the mask (3) and developing the image after exposure (Fig. i(b)). In the colored photosensitive resin composition layer, the light is not irradiated, and the light (4) is not irradiated, and the light is irradiated, and the light irradiation field (丨2) remains as it is not removed, and a black base is formed. Material or halogen (5) (Fig. 1 (c)). In order to improve the mechanical strength of the formed black substrate or pixel, heat treatment is usually performed after development, and the coloring photosensitive resin composition is replaced by one side. The color of the pigment is reversed, and the black substrate (5BM) and the color pixels (5R, 5G, and 5B) corresponding to the three primary colors can be sequentially formed, and the desired color filter (6) can be obtained (Fig. In these manufacturing methods, in order to form a finer black substrate or form 5 314839 !286268
