Description

  The present invention relates to a self-luminous photosensitive resin composition, a color filter manufactured using the same, and an image display device.

  2. Description of the Related Art The display industry has been rapidly changing from a cathode-ray tube (CRT) to a plasma display panel (PDP), an organic light-emitting diode (OLED), and a liquid-crystal display (LCD). . Among them, LCDs are thin, light, and have advantages such as excellent resolution and low power consumption, so they are widely used as image display devices used in almost all industries, and large market expansion is expected in the future. .

  In the LCD, as white light generated from a light source passes through a liquid crystal cell, transmittance is adjusted, and three primary colors that are transmitted through red, green, and blue color filters are mixed to realize a full color.

  A color filter is a thin film film type optical component that extracts three colors of red, green and blue from white light and enables it in fine pixel units.The size of one pixel is tens to hundreds of micrometers. It is about. Such a color filter includes a black matrix layer formed in a pattern defined on a transparent substrate and a plurality of colors (usually, It has a structure in which pixel portions in which three primary colors of red (R), green (G) and blue (B)) are arranged in a predetermined order are sequentially stacked.

  Therefore, the color filter is a core component for expressing colors in the LCD, and has been adopted for a wide range of uses such as a notebook computer, a monitor, and a portable terminal with the spread of flat panel displays. In order to realize more vivid image quality and superior quality to other displays, manufacturing techniques of high color purity, high transmission and low reflection type color filters are being actively researched.

  Generally, a color filter is manufactured by coating three or more hues on a transparent substrate by a pigment dispersion method, an electrodeposition method, a printing method, a dyeing method, a transfer method, an inkjet method, or the like. Recently, a pigment dispersion method using a pigment-dispersion type photosensitive resin excellent in quality, degree, and performance has become mainstream.

  The pigment dispersion method, which is one of the methods for realizing a color filter, is based on a transparent substrate provided with a black matrix, including a colorant, an alkali-soluble resin, a photopolymerizable monomer, a photopolymerization initiator, and an epoxy resin. After coating the photosensitive resin composition containing the solvent, other additives, and exposing the pattern in the form to be formed, by repeating a series of steps of removing the non-exposed portions with a solvent and heat curing, coloring This is a method of forming a thin film, and is actively applied to manufacture LCDs for mobile phones, notebook computers, monitors, televisions, and the like.

  Since the pigment is not dissolved in the solvent but exists in a fine particle state, it has reached a critical point for displaying sharper and more diverse hues recently required. On the other hand, dyes have better color characteristics than pigments, and research has been conducted to replace pigments with dyes. However, dyes also have poor durability to light and solvents, so there is a problem of improving this and securing sufficient solubility in the solvents used in the production of color filters, although the dyes are soluble in the solvents. Remains.

  Further, when a dye or a pigment is used as a colorant, a problem that transmission efficiency of a light source is reduced is caused. The reduction in the transmission efficiency results in a reduction in color reproducibility of the image display device, and ultimately makes it difficult to realize a high quality screen.

  As a result, in addition to excellent pattern characteristics, a variety of hue expressions, high color reproducibility, and even higher performance such as high brightness and a high contrast ratio are required. The use of quantum dots has been proposed.

  Quantum dots emit themselves by the light source and can be used to generate light in the visible and infrared regions. Quantum dots are small crystals of II-VI, III-V, IV-VI materials that typically have diameters between 1 nm and 20 nm, even smaller than the bulk exciton Bohr radius. Due to the quantum confinement effect, the difference in energy between the electronic states of a quantum dot is a function of both the composition and physical size of the quantum dot. Thus, the optical and optoelectronic properties of a quantum dot can be tuned and tuned by changing the physical size of the quantum dot. Quantum dots absorb wavelengths shorter than the onset absorption wavelength and emit light at the onset absorption wavelength. The bandwidth of the emission spectrum of a quantum dot is related to the temperature-dependent Doppler broadening, the Heisenberg Uncertainty Principle, and the size distribution of the quantum dot. For a given quantum dot, the emission band of the quantum dot can be controlled by varying the size. Thus, quantum dots can generate a range of unattachable colors using ordinary dyes and pigments.

  However, quantum dots are essentially non-scattering particles due to their nano-level size. Thus, when light passes through a color filter containing quantum dots, it has a much shorter optical path than other dyes and pigments. If the color filters are not thick enough, much light will be absorbed by the quantum dots. Accordingly, methods such as adjusting the thickness of a color filter, increasing the concentration of quantum dots, and introducing scattering particles have been proposed. Causes problems.

  Accordingly, in a method of introducing scattering particles into a color filter, Patent Document 1 relates to a self-luminous photosensitive resin composition, an image display device including a color filter manufactured therefrom, and more specifically, quantum dots, scattering particles. And a self-luminous photosensitive resin composition containing a photopolymerizable compound, a photopolymerization initiator, an alkali-soluble resin, and a solvent, and a color filter produced therefrom.

  Further, Patent Document 2 relates to a color filter and an image display device using the same, a base material; a first pixel layer including quantum dots formed on the base material; and scattering particles formed on the first pixel layer. Is characterized in that the second pixel layer including the above has a laminated structure.

  In the case of the above-mentioned prior art document, it includes quantum dots and an alkali-soluble resin, and describes that the reduction in light efficiency is eliminated, but it does not recognize the point of preventing sedimentation of scatterers in the color filter pattern. I understand.

Korean Patent Publication No. 10-2016-0060904 (2016.05.31. DONGWOO FINE-CHEM Co., Ltd.) Korean Patent Publication No. 10-2016-0091708 (2016.8.03. DONGWOO FINE-CHEM CO., LTD.)

  The present invention is to solve the above-described problem, and by including both a specific alkali-soluble resin and scattering particles, the scatterers in the color filter pattern do not settle, and the luminance is reduced. Another object of the present invention is to provide a photosensitive resin composition capable of producing an excellent color filter because there is no problem of poor light retention.

  Another object of the present invention is to provide a color filter manufactured using the self-luminous photosensitive resin composition and an image display device including the same.

  The self-luminous photosensitive resin composition according to an embodiment of the present invention for achieving the above object includes scattering particles and an alkali-soluble resin, and the alkali-soluble resin has a weight average molecular weight in terms of polystyrene of 3,000 to 15,000, The acrylic equivalent is 300 to 2000 g / eq.

  In addition, the present invention is characterized by a color filter manufactured using the self-luminous photosensitive resin composition and an image display device including the same.

  As described above, the self-luminous photosensitive resin composition according to the present invention comprises a scattering particle and an alkali-soluble resin having a polystyrene equivalent weight average molecular weight of 3,000 to 15,000 and an acrylic equivalent of 300 to 2,000 g / eq. An excellent color filter can be manufactured because the scatterers in the color filter pattern do not settle and there is no problem of a decrease in luminance and a poor light retention ratio.

FIG. 1 is a diagram showing that sedimentation appeared by measuring the TiO ₂ sedimentation property of the lower part of the pattern. FIG. 2 is a view showing that no sedimentation appears by measuring the TiO ₂ sedimentation property of the lower part of the pattern.

  The self-luminous photosensitive resin composition of the present invention contains scattering particles and an alkali-soluble resin, and the alkali-soluble resin has a polystyrene equivalent weight average molecular weight of 3000 to 15000 and an acrylic equivalent of 300 to 2000 g / eq. It is characterized by the following.

  Hereinafter, the self-luminous photosensitive resin composition will be described in detail as follows.

Alkali-Soluble Resin The alkali-soluble resin contained in the self-luminous photosensitive resin composition of the present invention makes the non-exposed portion of the photosensitive resin layer alkali-soluble so that it can be removed, and serves to leave exposed regions. . In addition, the alkali-soluble resin of the present invention has a polymerizable unsaturated bond, thereby effectively forming a protective layer around the surface of the quantum dot in the exposure step, and preventing high temperature and oxygen radicals in the POB process. High luminance can be maintained by eliminating the influence as much as possible.

  The alkali-soluble resin preferably has a weight average molecular weight in terms of polystyrene of 3,000 to 15,000, and when the weight-average molecular weight of the alkali-soluble resin is within the above range, it has an effect of reducing sedimentation of the scatterer. Can be.

  The alkali-soluble resin preferably has an acrylic equivalent of 300 to 2000 g / eq, and more preferably 500 to 1000 g / eq. When the acrylic equivalent of the alkali-soluble resin is within the above range, the phenomenon of quenching during the color filter step can be prevented. On the other hand, if the acrylic equivalent of the alkali-soluble resin exceeds the above range, the ability to effectively protect the quantum dots is insufficient, and it is difficult to prevent the scatterers from settling, so it is incompatible and acrylic. When the equivalent is less than the above range, the luminous efficiency and the sedimentation property are good, but there is a problem that it is not dissolved at the time of development and peeled off.

  In particular, the alkali-soluble resin according to the present invention, by adjusting the weight average molecular weight and the acrylic equivalent as described above, the composition is uniformly distributed in the pattern of the self-luminous photosensitive resin composition, and light scattering is effectively performed. When this occurs, it is possible to prevent the problem of the scatterer sedimenting, and it is possible to prevent a decrease in luminance and a poor light retention rate.

  The acid value of the alkali-soluble resin is preferably in the range of 30 to 150 mgKOH / g. The acid value is a value measured as the amount (mg) of potassium hydroxide required to neutralize 1 g of the acrylic polymer, and is related to solubility. When the acid value of the alkali-soluble resin falls within the above range, the solubility in the developer is improved, the unexposed portion is easily dissolved, the sensitivity is increased, and as a result, the pattern of the exposed portion is increased. There is an advantage that the film remains at the time of development and the film remaining ratio is improved. If the acid value of the alkali-soluble resin is less than the above range, the solubility in an alkali developing solution is low, there is a risk of leaving a residue on the substrate, and if the acid value exceeds the above range, pattern peeling occurs. Probability can be high.

  The molecular weight distribution of the alkali-soluble resin is preferably from 1.0 to 6.0, and more preferably from 1.5 to 4.0. When the molecular weight distribution of the alkali-soluble resin is within the above range, the developing property is excellent.

  In the case of a self-luminous photosensitive resin composition containing an alkali-soluble resin that satisfies the above conditions, a protective layer is effectively formed on the surface of the quantum dots in the exposure step, and the degree of curing in the matrix (Matirx) increases, It helps the scatterers to be evenly distributed with the quantum dots without settling at the bottom of the pattern.

  The alkali-soluble resin is not particularly limited as long as it has a polymerizable unsaturated bond. Specific examples of usable monomers include 3- (acryloyloxy) -2- Hydroxypropyl (meth) acrylate, 2-methoxy-3-prop-2-noyloxy-propyl) -2-methyl-2-propinoate, (2-oxydanyl-3-prop-2-noyloxy-propyl) -2-butinoate, 1,3-propanediol di (meth) acrylate, 1,3-butanediol di (meth) acrylate, hydroquinone di (meth) acrylate, 1,4-phenylenedi (meth) acrylate, 1,4-cyclohexanediol di ( Meth) acrylate, 2-propinoyloxymethyl-2-propinoate, triethylene glycol Di (meth) acrylate, tetraethylene glycol di (meth) acrylate, 1,6-hexanediol di (meth) acrylate, 1,12-dodecanediol di (meth) acrylate, trimethylolpromantri (meth) Acrylate, bisphenol A di (meth) acrylate, diurethane di (meth) acrylate, neopentyl glycol diacrylate, and the like are included.

When the content of the alkali-soluble resin is contained within the above range, the solubility in a developing solution is sufficient, so that pattern formation is easy, and a film reduction in a pixel portion of an exposed portion during development is prevented. In addition, the missing property of the non-pixel portion is improved.

Scattering particles The scattering particles are used to increase the light efficiency of a color filter. The light emitted from the light source is incident on the color filter at a critical angle.In this case, the incident light and the spontaneous emission light spontaneously emitted by the quantum dots meet scattering particles and increase the optical path. The light emission intensity is increased, thereby increasing the light efficiency of the color filter. The scattering particles can be any of ordinary inorganic materials, and preferably use metal oxides.

  The metal oxide is Li, Be, B, Na, Mg, Al, Si, K, Ca, Sc, V, Cr, Mn, Fe, Ni, Cu, Zn, Ga, Ge, Rb, Sr, Y, Mo, Cs, Ba, La, Hf, W, Tl, Pb, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Ti, Sb, Sn, Zr, An oxide containing one metal selected from the group consisting of Nb, Ce, Ta, In and combinations thereof is possible.

The scattering particles preferably have an average particle size of 10 to 1000 nm, more preferably have an average particle size in the range of 50 to 500 nm. If the size of the scattering particles is very small, a sufficient scattering effect of the light emitted from the quantum dots cannot be expected.On the other hand, if the size is very large, the light will sink into the composition or have a uniform quality. The surface of the self-luminous layer cannot be obtained.

  The self-luminous photosensitive resin composition according to the present invention is characterized in that the alkali-soluble resin contains scattering particles that are metal oxides together, so that the scattering particles can be prevented from settling over time. .

Quantum Dots The photosensitive resin composition of the present invention contains quantum dot particles. Quantum dots are nano-sized semiconductor materials. Atoms form molecules, and molecules form clusters of small molecules called clusters to form nanoparticles. When such nanoparticles have semiconductor characteristics, they are called quantum dots.

  The photosensitive resin composition of the present invention contains such quantum dot particles, and a color filter manufactured therefrom can emit light (photoluminescence) by light irradiation.

  In a general image display apparatus including a color filter, white light is transmitted through the color filter to realize a color. In this process, a part of the light is absorbed by the color filter, so that light efficiency is reduced.

  However, when a color filter manufactured using the photosensitive resin composition of the present invention is included, the color filter emits light by the light of the light source, thereby realizing higher light efficiency. In addition, since light having a hue is emitted, color reproducibility is further improved, and light is emitted in all directions by photoluminescence, so that the viewing angle can be improved.

  The quantum dot particle is not particularly limited as long as it is a quantum dot particle that can emit light when stimulated by light. For example, a II-VI semiconductor compound; a III-V semiconductor compound; a IV-VI semiconductor compound; Compounds containing the same; and combinations thereof.

  The quantum dot particles may be synthesized by a wet chemical process, a metal organic chemical vapor deposition process, or a molecular beam epitaxy process. The wet chemistry process is a method of growing particles by putting a precursor substance in an organic solvent. When the crystal grows, the organic solvent is naturally coordinated on the surface of the quantum dot crystal and acts as a dispersant to control the growth of the crystal. Therefore, metal organic chemical vapor deposition (MOCVD, metal organic) is performed. Nanoparticle growth can be controlled through an easier and less expensive process than a vapor deposition method such as chemical vapor deposition or molecular beam epitaxy (MBE).

  The content of the quantum dot particles according to the present invention is not particularly limited. More preferably, it is included. When the content of the quantum dots is less than the above range, the luminous efficiency may be insufficient, and when the content exceeds the above range, the content of other compositions is relatively insufficient, so that the pixel pattern may be reduced. There is a problem that it is difficult to form.

  The self-luminous photosensitive resin composition containing the photopolymerization initiator has high sensitivity, and a pixel pixel formed using the composition can have good strength and patternability of the pixel portion.

  Further, when a photopolymerization initiator is used in combination with the photopolymerization initiator, the self-luminous photosensitive resin composition containing these becomes more sensitive, and a color filter is formed using this composition. This is preferable because the productivity of the compound is improved.
