Description

Photosensitive resin composition and application thereof

The present invention relates to a photosensitive resin composition, and more particularly to a photosensitive resin composition for a color filter having excellent sputtering resistance and a color filter and a liquid crystal display device formed therefor.

At present, color filters have been widely used in the fields of color liquid crystal displays, color facsimile machines, color cameras and the like. As the market demand is expanding, the production technology of color filters is also diversified. At present, dyeing methods, printing methods, electroplating methods, and dispersion methods have been developed, among which the dispersion method is the mainstream process.

In the dispersion method, the coloring pigment is first dispersed in a photosensitive resin, and the photosensitive resin is applied onto a glass substrate, and a specific pattern can be obtained by exposure, development, and the like. After repeating the operation three times, a pattern of a red (R), green (G), and blue (B) pixel colored layer can be obtained, and then a protective film can be applied to the pattern of the pixel colored layer as needed.

For example, as disclosed in Japanese Laid-Open Patent Publication No. Hei. It is used as an alkali-soluble resin of a photosensitive resin.

However, in the manufacturing process of the color filter, it is necessary to undergo multiple heat treatment steps, such as red (R), green (G), and blue (B), and the like, after the formation of the colored layer pattern is post-bake. a step of forming a transparent conductive film (ITO film), etc., which are generally required to be operated at a high temperature of 200 ° C or higher, but the above-mentioned photosensitive resin is easily heated at 180 ° C for about 1 hour. Pigment aggregated particles are generated in the pigmented layer (generally, the pigment agglomerated particles have a particle diameter of from 1 μm to 10 μm), and the heat resistance of the pixel colored layer is also poor.

In order to improve the above-mentioned problem, a photosensitive resin composition comprising a polymer obtained by polymerizing an unsaturated monomer of a carboxylic acid group and a monomer containing a glycidyl group is disclosed in JP-A-2001-075273. An alkali-soluble resin of a photosensitive resin. However, in the sputtering forming process of the subsequent transparent conductive film, the color filter obtained by using the photosensitive resin composition of the prior art described above has a problem of poor sputtering resistance, especially the pixel coloring layer is After being subjected to the sputtering process of a strong electron beam, problems such as chromaticity loss are liable to occur.

In view of the above, there is a need to develop a photosensitive resin composition that overcomes problems such as poor sputtering resistance and chromaticity loss of a conventional photosensitive resin composition.

Therefore, an aspect of the present invention provides a photosensitive resin composition comprising a photoinitiator (E) having a specific structure and a compound (F) to provide a photosensitive resin composition having better sputter resistance. .

Another aspect of the present invention provides a method of producing a color filter using the above-described photosensitive resin composition to form a pixel layer.

Still another aspect of the present invention provides a color filter which is produced by the above method.

Still another aspect of the present invention provides a liquid crystal display device comprising the above color filter.

According to the above aspect of the invention, there is provided a photosensitive resin composition comprising a pigment (A), a dye (B), an alkali-soluble resin (C), a compound (D) containing an ethylenically unsaturated group, and a light-initiating The agent (E), the compound (F), and the solvent (G) are described below.
