Problems solved by technology

However, if this is done, the aperture ratio will decrease, and sufficient brightness cannot be produced. In addition, due to the large number of black matrix patterns, there will be problems in flatness during resist coating, and there may be uncoated parts.
[0007] Such a problem is considered to be a problem that has recently occurred on the way to high-precision displays. In order to solve the above-mentioned problem, there is no special solution except for reducing the viscosity by reducing the solid content of the resist.
[0008] However, if the viscosity is lowered only by reducing the solid content, there are disadvantages in that the flatness of coating with a slit coater will be greatly affected, unevenness in brightness will occur, and defects will increase.
For example, Patent Document 1 discloses a colored photosensitive resin composition, but the above-mentioned prior art has the following problems: poor flatness due to poor coating performance, and poor developing speed

Description

technical field [0001] The present invention relates to a colored photosensitive resin composition, a color filter manufactured using the same, and an image display device. Background technique [0002] Color filters are widely used in various display devices such as imaging elements and liquid crystal display devices (LCD), and the range of applications thereof is rapidly expanding. The above-mentioned color filter is composed of a coloring pattern of three colors of red (Red), green (Green) and blue (Blue), or a coloring pattern of three colors of yellow (Yellow), magenta (Magenta) and cyan (Cyan) pattern composition. [0003] Each colored pattern of the above-mentioned color filter is generally formed with a colored photosensitive resin composition containing a colorant such as a pigment or a dye, a binder resin, a photopolymerizable compound, a photopolymerization initiator, and a solvent. Colored pattern processing using the said colored photosensitive resin compositi...
