Description

Photosensitive resin composition, method for producing color filter, color filter, and liquid crystal display device

Technical field

The present invention relates to a photosensitive resin composition, a method of producing a color filter, a color filter, and a liquid crystal display device. In particular, it relates to a photosensitive resin composition having high linearity, high outgassing property, and good pattern smoothness, and a color filter and a liquid crystal display device formed using the photosensitive resin composition.

Background technique

At present, color filters have been widely used in the fields of office equipment such as color liquid crystal displays, color facsimile machines, and color cameras. 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 colored pigment is first dispersed in a photosensitive resin, and the photosensitive resin is applied onto a glass substrate, and a specific pattern is obtained by exposure, development, and the like. By repeating the operation three times, a pattern of red (R), green (G), and blue (B) pixel colored layers can be obtained, and then a protective film can be applied on the pattern of the pixel colored layer as needed.

For example, a copolymer obtained by polymerizing (meth)acrylic acid as a monomer component, as disclosed in JP-A-6-95211, and JP-A-H08-183819, This is an alkali-soluble resin as a photosensitive resin.

However, in the manufacturing process of the color filter, it is necessary to undergo a plurality of heat treatment steps, such as red (R), green (G), and blue (B), and the post-bake step after the formation of the pixel colored layer pattern. And a step of forming a transparent conductive film (ITO film), etc., these steps generally need to be operated at a high temperature of 200 ° C or higher, but the above-mentioned known photosensitive resin is heated at 180 ° C for about 1 hour, but in the pixel The generation of pigment agglomerated particles tends to occur in the colored layer (generally, the particle diameter of the pigment agglomerated particles is from 1 to 10 μm), and the heat resistance of the pixel colored layer is also not good.

In order to improve the above-mentioned problems, the photosensitive resin composition disclosed in Japanese Laid-Open Patent Publication No. 2001-075273, A polymer obtained by polymerizing a carboxyl group-containing unsaturated monomer and a glycidyl group-containing monomer is used as an alkali-soluble resin of a photosensitive resin.

The color filter is prepared by sequentially pre-baking, exposing, developing, and post-baking the photosensitive composition on the substrate on which the black matrix has been formed, wherein the black matrix is used to isolate each pixel layer. The preparation method of the color filter will be described in detail below.

First, a photosensitive resin composition for a color filter in a solution state is uniformly applied onto a substrate by a coating method such as spin coating or cast coating or roll coating to form a coating film. The substrate is, for example, an alkali-free glass, a soda-lime glass, a hard glass (Pyles glass), a quartz glass, and the like to which a transparent conductive film is attached, which is used for a liquid crystal display device; A substrate (for example, a silicon substrate) of a solid-state imaging device; or a substrate having a black matrix for shielding light that can separate pixel layers such as red, green, and blue.
