Description

Quantum dot dispersion, self-luminous photosensitive resin composition, color filter and image display device manufactured using the same

The present invention relates to a quantum dot dispersion, a self-luminous photosensitive resin composition, and a color filter manufactured using the same, which are excellent in dispersing properties and harmless to a human body.

The color filter is a thin film type optical component that extracts three colors of red, green, and blue from white light and makes them possible in fine pixel units. The size of one pixel is about tens to hundreds of micrometers. Such a color filter includes a black matrix layer formed in a predetermined pattern on a transparent substrate to shield the boundary between each pixel, and a plurality of colors (typically red (R), green (G) and The pixel units in which the three primary colors of blue (B) are arranged in a predetermined order are stacked in this order.

Recently, as one of the methods of implementing a color filter, a pigment dispersion method using a pigment-dispersible photosensitive resin has been applied, but a part of the light is absorbed by the color filter while the light emitted from the light source passes through the color filter. The problem is that the efficiency is lowered and the color reproduction is lowered due to the characteristics of the pigment contained in the color filter.

In particular, as color filters are used in various fields, including various image display devices, not only excellent pattern characteristics but also high color reproducibility and excellent performance such as high brightness and high contrast ratio are required. A color filter manufacturing method using the self-luminous photosensitive resin composition containing is proposed.

Korean Patent Laid-Open Publication No. 2006-0084668 relates to a quantum dot phosphor, and discloses a light emitting diode which maintains excellent light emission efficiency by including a quantum dot and a solid carrier supporting the quantum dot.

However, the Republic of Korea Patent Publication No. 2006-0084668 uses a solvent harmful to the human body such as chloroform, toluene, hexane and the like excellent dispersibility as a dispersing solvent for dispersing the quantum dot phosphor. Solvents described above are highly volatile compounds (Volatile Organic Compound) or carcinogenic, neurotoxic, and have a high risk of abnormal reproductive function.

Therefore, in order to use these quantum dots, solvents that are harmful to the human body through drying or dispersing solvents are not removed and are not highly volatile compounds, are not carcinogenic, neurotoxic, and have no or low risk of reproductive function. Subsequently, the quantum efficiency decreases, and thus, the light emission characteristics of the color filter or the image display device are lowered.

Therefore, there is a demand for the development of a quantum dot dispersion liquid that exhibits excellent dispersibility to quantum dots, is excellent in light emission characteristics of a color filter or an image display device manufactured using the same, and does not contain harmful components.

<Quantum store dispersion>

One aspect of the invention relates to a quantum dot dispersion. Specifically, one embodiment of the present invention comprises a quantum dot and a solvent, the solvent satisfies the conditions of the Hansen solubility parameter of the following equation (1), halogenated hydrocarbon-based solvents; Aromatic hydrocarbon solvents; And an aliphatic hydrocarbon solvent; and a quantum dot dispersion liquid not included.

[Equation 1]

(In Equation 1,

δ _d is the dispersion component, δ _p is the polar component, and δ _h is the hydrogen bonding component.)

Quantum dot dispersions in accordance with an aspect of the present invention include quantum dots. The quantum dots may refer to nanoscale semiconductor materials. Atoms form molecules, and molecules form clusters of small molecules called clusters that form nanoparticles, which are called quantum dots when they are semiconducting. When the quantum dots reach the excited state from the outside, the quantum dots emit energy according to their corresponding energy bandgap.

The color filter made of the self-luminous photosensitive resin composition containing the quantum dot dispersion liquid according to one embodiment of the present invention can emit light (luminescence) by light irradiation by including the quantum dots.

In a typical image display apparatus including a color filter, white light is transmitted through the color filter to implement color. In this process, a part of the light is absorbed by the color filter, thereby degrading light efficiency. However, in the case of including the color filter made of the self-luminous photosensitive resin composition according to the present invention, since the color filter is self-luminous by the light of the light source, it is possible to implement more excellent light efficiency, and also emit light with color Since the color reproducibility is excellent, and the light is emitted in all directions by the photoluminescence, the viewing angle is also improved.

The quantum dot is not particularly limited as long as it is a quantum dot particle capable of emitting light by stimulation caused by light. For example, group II-VI semiconductor compound; Group III-V semiconductor compounds; Group IV-VI semiconductor compounds; A Group IV element or a compound containing the same; And it can be selected from the group consisting of these, these can be used alone or in combination of two or more.

Specifically, the II-VI semiconductor compound may be selected from the group consisting of CdS, CdSe, CdTe, ZnS, ZnSe, ZnTe, ZnO, HgS, HgSe, HgTe, and mixtures thereof; CdSeS, CdSeTe, CdSTe, ZnSeS, ZnSeTe, ZnSTe, HgSeS, HgSeTe, HgSTe, CdZnS, CdZnSe, CdZnTe, CdHgS, CdHgSe, CdHgTe, HgZnS, HgZnSe, HgZnTe And an elemental compound selected from the group consisting of CdZnSeS, CdZnSeTe, CdZnSTe, CdHgSeS, CdHgSeTe, CdHgSTe, HgZnSeS, HgZnSeTe, HgZnSTe, and mixtures thereof.

The group III-V semiconductor compound may be selected from the group consisting of GaN, GaP, GaAs, GaSb, AlN, AlP, AlAs, AlSb, InN, InP, InAs, InSb, and mixtures thereof; Three-element compounds selected from the group consisting of GaNP, GaNAs, GaNSb, GaPAs, GaPSb, AlNP, AlNAs, AlNSb, AlPAs, AlPSb, InNP, InNAs, InNSb, InPAs, InPSb, GaAlNP and mixtures thereof; And an elemental compound selected from the group consisting of GaAlNAs, GaAlNSb, GaAlPAs, GaAlPSb, GaInNP, GaInNAs, GaInNSb, GaInPAs, GaInPSb, InAlNP, InAlNAs, InAlNSb, InAlPAs, InAlPSb and mixtures thereof.

The Group IV-VI semiconductor compound may be selected from the group consisting of SnS, SnSe, SnTe, PbS, PbSe, PbTe, and mixtures thereof; A three-element compound selected from the group consisting of SnSeS, SnSeTe, SnSTe, PbSeS, PbSeTe, PbSTe, SnPbS, SnPbSe, SnPbTe, and mixtures thereof; And SnPbSSe, SnPbSeTe, SnPbSTe, and one or more selected from the group consisting of an elemental compound selected from the group consisting of mixtures thereof, but are not limited thereto.

Although not limited thereto, the group IV element or a compound including the same may include an element compound selected from the group consisting of Si, Ge, and mixtures thereof; And a binary element compound selected from the group consisting of SiC, SiGe, and mixtures thereof.

The quantum dots are homogeneous single structures; Dual structures such as core-shell, gradient structures, and the like; Or a mixed structure thereof.

Specifically, in the dual structure of the core-shell, the material constituting each core and shell may be made of the above-mentioned different semiconductor compounds. For example, the core may include one or more materials selected from the group consisting of CdSe, CdS, ZnS, ZnSe, CdTe, CdSeTe, CdZnS, PbSe, AgInZnS, and ZnO, but is not limited thereto. The shell may include one or more materials selected from the group consisting of CdSe, ZnSe, ZnS, ZnTe, CdTe, PbS, TiO, SrSe, and HgSe, but is not limited thereto.

The quantum dots may be synthesized by a wet chemical process, a metal organic chemical vapor deposition (MOCVD), or a molecular beam epitaxy (MBE), but are not limited thereto. .

The wet chemical process is a method of growing a particle by adding a precursor material to an organic solvent. When the crystal grows, the organic solvent naturally coordinates the surface of the quantum dot crystal and acts as a dispersant to control the growth of the crystal. Therefore, the nano solvent is easier and cheaper than the vapor deposition method such as the organometallic chemical vapor deposition process or molecular beam epitaxy. Since the growth of the particles can be controlled, it is preferred to produce the quantum dots according to the invention using the wet chemical process.

In one embodiment of the present invention, the quantum dots may further include an organic ligand. The organic ligand may be bound to the surface of the quantum dots to serve to stabilize the quantum dots. The organic ligand is not limited in the present invention, such as C5 to C20 alkyl carboxylic acid, alkenyl carboxylic acid or alkynyl carboxylic acid; Alkyl carboxylic acids, al, C5 to C20, which may include thiol, phosphoric acid, pyridine, mercapto alcohol, phosphine, phosphine oxide, etc., and in terms of improving stability by effectively protecting the surface of the quantum dot. Kenyl carboxylic acid or alkynyl carboxylic acid; It is preferable to include one or more selected from the group consisting of thiol and phosphoric acid.

The organic ligand may cover 5% or more of the surface of the total area of the quantum dots.

The organic ligand may be included in the quantum dot dispersion in the form of a commercially available form, or may be added directly to the quantum dot dispersion when not included in the quantum dot dispersion, and the organic ligand may be added directly to the quantum dot dispersion. In this case, the content may be added in an amount of 0.1 to 10 moles with respect to 1 mole of the quantum dot.

According to one embodiment of the invention, the quantum dots may be included in 5 to 70% by weight, preferably 10 to 65% by weight, more preferably 15 to 60% by weight relative to the total 100% by weight of the quantum dot dispersion. . When the quantum dot is included in the above range, it is possible to provide a self-luminous photosensitive resin composition having excellent photosensitivity. When the quantum dot is included in the range below the photosensitive properties may be slightly reduced, and when included in excess of the above range, the content of the other components, such as alkali-soluble resin, photopolymerizable compound to be described later in contrast to the quantum dot Since it is relatively small, there is a problem that the manufacture of the color filter may be somewhat difficult, so it is preferably included within the above range.

The quantum dot dispersion according to the present invention has an advantage of uniformly dispersing the quantum dots by including a solvent that satisfies the conditions of the Hansen solubility parameter of Equation 1 below, halogenated hydrocarbon solvent such as chloroform or dichloromethane harmful to human body; Aromatic hydrocarbon solvents such as benzene or toluene; And aliphatic hydrocarbon-based solvents such as N-hexane, there is an advantage that can prevent workers to deal with this dangerous environment such as carcinogenicity, neurotoxicity, causing reproductive dysfunction.

Production Example  3: Manufacture of color filter

The color filter was manufactured using the self-luminous photosensitive resin composition prepared in Examples 1 to 7 and Comparative Examples 1 to 4 below. Specifically, each of the self-luminous photosensitive resin composition was applied on a glass substrate by spin coating, then placed on a heating plate and maintained at a temperature of 100 ° C. for 3 minutes to form a thin film. Subsequently, a test photomask having a 20 mm × 20 mm square transmission pattern and a line / space pattern of 1 μm to 100 μm was placed on the thin film, and the ultraviolet rays were irradiated with a distance of 100 μm from the test photomask.

At this time, the ultraviolet light source was irradiated with an exposure amount (365 nm) of 200 mJ / cm ² in an air atmosphere using an ultra high pressure mercury lamp (trade name USH-250D) manufactured by Ushio Denki Co., Ltd., and no special optical filter was used. The thin film irradiated with ultraviolet rays was developed by soaking for 80 seconds in a KOH aqueous solution developing solution of pH 10.5. The thin film coated glass plate was washed with distilled water, dried by blowing nitrogen gas, and heated in a heating oven at 150 ° C. for 10 minutes to prepare a color filter pattern. The film thickness of the prepared self-luminous color filter pattern was 3㎛.

Experimental Example

Experimental Example  One: Quantum dots  Dispersions and Self-luminescence  Dispersion particle size measurement of photosensitive resin composition

Dispersion particle size was measured using ELSZ-2000ZS (manufactured by Otsuka Co., Ltd.) and listed in Table 3 below. As the quantum dot particles aggregate, the dispersion particle size increases.

Experimental Example  2: Measurement of Intensity

The emission intensity in the 550 nm region of the color filter manufactured in Preparation Example 3 was measured using a spectrometer (manufactured by Ocean Optics, Inc.), and is shown in Table 3 below. It is determined that the greater the measured emission intensity is, the better the self-luminous property is.
