Description

TECHNICAL FIELD [0001] The present invention relates to a photosensitive resin composition, a photosensitive material made of the photosensitive resin composition, a color filter including the same, and a display device including the photosensitive material. BACKGROUND OF THE INVENTION DEVICE HAVING THE PHOTOSENSITIVE MATERIAL}

This specification claims the benefit of the filing date of Korean Patent Application No. 10-2012-0058408 filed on May 31, 2012, the entire contents of which are incorporated herein by reference.

The present invention relates to a photosensitive resin composition, a photosensitive material made of the photosensitive resin composition, a color filter including the photosensitive material, and a display device including the photosensitive material.

Generally, a color filter is used for a liquid crystal display, an optical filter of a camera, and the like, and is manufactured by coating a fine area colored with three or more colors onto a solid-state image sensor or a transparent substrate. Such a colored thin film is generally formed by a dyeing method, a printing method, an electrodeposition method, a pigment dispersion method or the like.

In the case of the staining method, an image having a dye base material such as a natural photosensitive resin such as gelatin or the like, an amine-modified polyvinyl alcohol, or an amine-modified acrylic resin is formed on the substrate in advance, and then the resultant is dyed with a dye such as a direct dye to form a colored thin film. It is necessary to perform flame-retardant processing every time the color is changed in order to form a multicolor thin film on the same substrate, which complicates the process and delays the time. Further, the dye and the resin itself which are generally used are good in terms of sharpness and dispersibility, but they are disadvantageous in that they have poor light resistance, moisture resistance and heat resistance, which is the most important characteristic.

In the case of the printing method, since printing is performed using an ink in which a pigment is dispersed in a thermosetting or photocurable resin, and then the ink is cured by heat or light to form a colored thin film, the material cost can be reduced compared to other methods. However, Image formation is difficult and the thin film layer to be formed is not uniform.

The pigment dispersion method is a method in which a thin film is formed by repeating a series of processes of coating, exposing, developing, and thermally curing a photopolymerizable composition on a transparent substrate. The pigment dispersion method can improve the heat resistance and durability, which are the most important properties of the color filter, and has the advantage that the thickness of the film can be uniformly maintained.

The photosensitive resin composition used in the production of a color filter according to the pigment dispersion method generally comprises a binder resin, a polyfunctional monomer, an initiator, a solvent, and other additives.
