Thermosetting resin composition for producing color filter for CMOS image sensor, color filter comprising transparent film formed using the composition and CMOS image sensor using the color filter

Glycidyl-, OH-, COOH- and aryl-(meth)acrylate copolymer for color filter

Disclosed herein is a novel functional diamine compound having a dendron structure, polyamic acid which is produced using functional diamine, aromatic cyclic diamine, aliphatic cyclic acid dianhydride, and aromatic cyclic acid dianhydride, polyimide which is produced by imidizing polyamic acid, and an LC alignment film produced using polyimide. Even if the diamine compound is used in a small amount, it is possible to realize a high pretilt angle, thus the pretilt angle is easily controlled. Therefore, it can be used to produce an LC alignment film using a twisted nematic (TN) mode, in which the pretilt angle of liquid crystal is low, and a vertically aligned (VA) mode, which requires a high pretilt angle of about 90&#xb0;.

Provided herein are one-solution type thermosetting resin compositions that may be useful to form protective films for color filters used in liquid crystal displays or image sensors. According to some embodiments, the resin compositions may include a self-curable copolymer and an epoxy compound. The protective films may exhibit desirable flatness, adhesiveness, transmittance, heat resistance and chemical resistance. Also provided are methods of forming a film on a substrate, and substrates having a film formed thereon. In addition, provided herein are color filters including a film formed from a composition according to an embodiment of the invention, and liquid crystal displays and image sensors including such color filters.

Diamine compound containing specific triazine group, polyamic acid obtained by reacting the diamine compound and tetracarboxylic dianhydride, and liquid crystal alignment film obtained by coating and imidizing the polyamic acid. The liquid crystal alignment film has good heat-resistance, high transparency in visible light region and improved voltage holding ratio. Also, pretilt angle is easily controlled over broad range.

Disclosed herein is an LC aligning agent using diamine having dendron side chains. In detail, the present invention relates to a composition for an LC alignment film which employs diamine having dendron side chains to produce polyamic acid, followed by imidization. When the LC alignment film is applied to a liquid crystal display device, high heat resistance, high penetration in a visible ray range, excellent alignment, and a high voltage holding ratio are assured. Even though it contains a small amount of functional diamine, a high pretilt angle can be assured. Thus, the pretilt angle is easily controlled and a vertical aligning force is improved.
