Description

Colored photosensitive resin composition, color filter manufactured using the same, and image display device

The present invention relates to a colored photosensitive resin composition, a color filter produced therewith, and an image display device.

Color filters are widely used in various display devices such as image pickup devices and liquid crystal display devices (LCDs), and their application ranges are rapidly expanding. The color filter is composed of three color schemes of red, green, and blue, or yellow, magenta, and cyan. Pattern composition. Each of the coloring patterns of the color filter is generally formed of a coloring photosensitive resin composition containing a coloring agent such as a pigment or a dye, a binder resin, a photopolymerizable compound, a photopolymerization initiator, and a solvent. The coloring pattern processing using the above-described colored photosensitive resin composition is usually carried out by a lithography process. As such a colored photosensitive resin composition, a composition containing a photopolymerizable compound and a photopolymerization initiator together with a pigment and a binder resin is often used. In the case of today's monitors, high-resolution models are rapidly increasing in order to transmit more realistic images, especially for mobile phones and tablet PCs used as personal portable devices, requiring high precision of 500 ppi or more. It requires even smaller pixel sizes than TVs and monitors that are viewed from a distance. With the increase in precision, in order to place a large number of pixels in a limited space, the area of the black matrix must become large. However, if this is done, the aperture ratio is lowered, sufficient brightness cannot be generated, and in addition, due to a large number of black matrix patterns, problems occur in flatness at the time of resist coating, and it is possible to cause uncoated. section. Such a problem is regarded as a problem that has recently occurred on the way to high precision of the display. In order to solve the above problems, there is no special solution other than merely reducing the content of the solid content of the resist to lower the viscosity. However, if the content of the solid component is lowered to lower the viscosity, there is a disadvantage in that it has a large influence on the flatness when applied by a slit coater, and uneven brightness is generated, which is undesirable. For example, Patent Document 1 discloses the content of the colored photosensitive resin composition, but the above prior art has a problem in that the flatness is poor and the developing speed is also poor due to poor coating performance.
