Description
The present invention relates to a blue photosensitive resin composition, a color filter, and a liquid crystal display including the same.
BACKGROUND ART [0002] Color filters are widely used in imaging devices, liquid crystal display devices, and the like, and their application range is rapidly expanding. A color filter used for a color liquid crystal display device, an image pickup device, or the like is generally formed by uniformly applying a colored photosensitive resin composition containing a colorant corresponding to red, green and blue colors on a substrate on which a black matrix is patterned by spin coating (Hereinafter also referred to as "post-baking") is repeated for each color so as to obtain a pixel of each color As shown in FIG.
As such a colored photosensitive resin composition, a photosensitive resin composition containing an alkali soluble binder resin, a photopolymerizable compound, a photopolymerization initiator, a pigment solvent, and a black pigment in the formation of a black matrix is used.
Particularly, among the photosensitive resin compositions, the blue pigment has a short wavelength (about 400 nm in the second half) region, unlike the other color pigments, and the toxic adhesion is deteriorated in a high temperature and high humidity environment.
Recently, an example of using an oxime ester fluorene derivative compound as a photopolymerization initiator to achieve low exposure and high sensitivity has been disclosed, but this does not solve the problem that deterioration of the quality of a liquid crystal display device occurs due to peeling of a color filter in a blue pigment Respectively.
Korean Patent Laid-Open No. 10-2013-0124215 (published on Mar. 13, 2013) discloses a novel oxime ester fluorene compound, a photopolymerization initiator containing the same, and a photoresist composition. The above-mentioned prior art provides a photoresist composition which uses oxime ester fluorene derivative compound as a photopolymerization initiator and has a sensitivity higher than that of the oxime ester fluorene derivative compound.

The present invention also provides a color filter made of the blue photosensitive resin composition.
When the color filter of the present invention is applied to an image display apparatus, since it emits light by the light of the display apparatus light source, it is possible to realize more excellent light efficiency. In addition, since color light is emitted, color reproducibility is better and light is emitted in all directions due to the optical luminescence, so that the viewing angle is improved and the luminance characteristic is excellent.
The color filter includes a substrate and a pattern layer formed on the substrate.
The substrate may be a substrate of the color filter itself, or may be a portion where the color filter is placed on a display device or the like, and is not particularly limited. The substrate may be glass, silicon (Si), silicon oxide (SiO x ), or a polymer substrate. The polymer substrate may be polyethersulfone (PES) or polycarbonate (PC).
The pattern layer may be a layer containing the photosensitive resin composition of the present invention, and may be a layer formed by applying the photosensitive resin composition and exposing, developing, and curing the composition in a predetermined pattern.
The pattern layer formed of the colored photosensitive resin composition may have a red pattern layer containing the red quantum dot particles, a green pattern layer containing the green quantum dot particles, and a blue pattern layer containing the blue quantum dot particles. During the light irradiation, the red pattern layer emits red light, the green pattern layer emits green light, and the blue pattern layer emits blue light.
In such a case, the emitted light of the light source is not particularly limited when applied to an image display apparatus, but a light source that emits blue light preferably in terms of better luminance and color reproducibility can be used.
According to another embodiment of the present invention, the pattern layer further includes a red pattern layer, a green pattern layer, and a transparent pattern layer not containing the quantum dot particles. In the case where only the pattern layer of two colors is provided, a light source that emits light having a wavelength that represents the remaining color that is not included can be used. For example, when a red pattern layer and a green pattern layer are included, a light source that emits blue light can be used. In such a case, red quantum dot particles emit red light and rust quantum dot particles emit green light, and the transparent pattern layer transmits blue light as it is and exhibits blue color.
The color filter including the substrate and the pattern layer as described above may further include a partition wall formed between the respective patterns, and may further include a black matrix. Further, it may further comprise a protective film formed on the pattern layer of the color filter.
By including the blue pigment in the color filter, it is possible to prevent the problem that peeling may occur in the substrate and the pattern layer in a high temperature and high humidity environment.
In addition, the present invention provides a liquid crystal display device including a color filter made of the blue photosensitive resin composition. Therefore, the adhesion of the color filter can be increased, and the problem of quality deterioration of the liquid crystal display device can be prevented.

(2) Development speed, sensitivity, pattern subtraction and pattern straightness evaluation
The development speed, sensitivity and pattern straightness of the color filter made of the blue photosensitive resin compositions of Examples 1 to 4 and Comparative Examples 1 to 3 were evaluated, and the results are shown in Table 3 below.
The development speed was measured by measuring the time taken for the unexposed area to completely dissolve in the developing solution at the time of development, and the minimum exposure amount required to form a thin film without pattern peeling after the development of sensitivity was measured.
In addition, when the generated pattern was evaluated by an optical microscope, the degree of peeling was indicated on the pattern. O = no peeling off of pattern,? = 1 to 3 pattern peeling, X = pattern peeling 4 And XX = torn bundle.
The pattern straightness evaluation showed the degree of irregularity and curvature on the pattern when the generated pattern was evaluated through an optical microscope. O = no error in pattern, Δ = 1 to 3 pattern errors, X = pattern 4 errors or more, XX = unexplained, or impossible to measure.

Referring to Table 3, it can be seen that Examples 1 to 4 prepared according to the present invention have a high developing speed, excellent sensitivity, no pattern peeling, and no pattern error. Therefore, in Examples 1 to 4, a color filter pattern having excellent quality can be produced.
On the other hand, in Comparative Examples 1 to 3 in which the oxime ester fluorene derivative compound was not used as a photopolymerization initiator, pattern peeling and pattern errors were observed on the substrate, and the sensitivity was not excellent.
