Description

Self-luminous photosensitive resin composition, color filter and image display device including a color conversion layer using the same {SELF EMISSION TYPE PHOTOSENSITIVE RESIN COMPOSITION, COLOR FILTER COMPRISING COLOR CONVERSION LAYER USING THE SAME AND DISPLAY DEVICE}

The present invention relates to a self-luminous photosensitive resin composition with excellent color conversion properties and fluorescence retention, a color filter including a color conversion layer using the same, and an image display device.

Recently, the display industry has undergone a rapid change from CRT (cathode-ray tube) to flat panel displays such as PDP (plasma display panel), OLED (organic light-emitting diode), and LCD (liquid-crystal display). Among them, LCD is widely used as an image display device used in almost all industries, and its application range is continuously expanding.

LCD's transmittance is adjusted as white light generated from the backlight unit passes through the liquid crystal cell, and the three primary colors passing through the color filters of red, green, and blue are mixed to achieve full color.

CCFL (Cold Cathode Fluorescent Lamp) is used as the light source of the backlight unit, but in this case, the backlight unit must always supply power to the CCFL, which causes the problem of power consumption. In addition, compared to existing CRTs, a color reproduction rate of about 70% and environmental pollution problems due to the addition of mercury are pointed out as disadvantages.

As a replacement to solve the above problems, research is currently being actively conducted on backlight units using LEDs (Light Emitting Diodes). When using LED as a backlight unit, it can exceed 100% of the NTSC (National Television System Committee) color reproduction range specification, providing consumers with more vivid picture quality.

Accordingly, in the same industry, methods are being proposed to improve the efficiency of the backlight light source by changing the materials and structure of the color filter and LCD panel.

A color filter forms pixels of each color through a patterning process after applying a dispersion composition containing pigment or dye. These pigments and dyes cause the problem of lowering the transmission efficiency of the backlight light source. The decrease in transmission efficiency ultimately lowers the color reproducibility of the display device, ultimately making it difficult to implement a high-quality screen. Therefore, research is being conducted to further improve color reproducibility.

In this regard, Korean Patent Publication No. 10-2018-0065326 discloses quantum dots; binder resin; photopolymerizable monomer; photopolymerization initiator; A photosensitive resin composition that can improve the dispersibility and chemical resistance of quantum dots by including a compound and a solvent containing a repeating unit of a specific chemical formula has been described, but the effect of improving color reproducibility is minimal and there is a problem of color transfer occurring. There is.

The problem of low color reproducibility can be solved by increasing the light efficiency of the color filter, and a method of increasing the thickness of the color filter or introducing a color conversion layer (or light conversion layer) laminated or close to it has been proposed. .

Figure 1 is a schematic diagram showing the role of the color conversion layer in the display device. As shown in Figure 1, the light source generated from the backlight 10 directly increases light efficiency through the color conversion layer 20 and the pixel portion 30. You can.

However, dyes or pigments have been used in the composition of the color conversion layer 20, but it is difficult to expect improvement in light efficiency with these dyes and pigments alone, and the problem of lowering luminance occurs. Accordingly, the use of a fluorescent material as a material for the color conversion layer 20 has been proposed.

The fluorescent material is excited by blue light emitted from the backlight 10, and changes the wavelength of the blue light to emit light in the front direction to emit white light such as red white light or green white light, resulting in light efficiency. improves

In addition, a grid-like black pattern called a black matrix is placed between the color pixels of the color filter. In order to realize a large screen area and high contrast, the black matrix of the color filter is required to have sufficient light blocking properties and be patterned at high resolution.

In response to the slimming of displays and the demand for wider screens, technology is being applied to enlarge the screen by even 1 inch by using the minimum area for the upper and lower plates of the module joined together. One of the methods is a new type of screen. A cementation method is proposed. In the existing bonding method, the border of the glass and black matrix was used simultaneously to bond the glass, but the display efficiency on the panel was reduced by bonding using glass larger than the actual visible area. On the other hand, in order to increase the efficiency of the display, a new type of bonding method is attempting to maximize the efficiency of the display in the panel by only bonding on the black matrix part without using glass during bonding. To develop this method, black The technology of including a cardo-based binder in the black photosensitive resin composition constituting the matrix has been widely used in the past.

When light is irradiated, the red pattern layer emits red light, the green pattern layer emits green light, and the blue pattern layer emits blue light.

In such cases, the emission light of the light source is not particularly limited when applied to an image display device, but a light source that emits blue light can be used in terms of better color reproduction.

The pattern layer may include only two color pattern layers among a red pattern layer, a green pattern layer, and a blue pattern layer. In such a case, the pattern layer may further include a transparent pattern layer that does not contain quantum dot particles.

In the case where only two color pattern layers are provided, a light source that emits light with a wavelength representing the remaining colors not included can be used. For example, when it includes a red pattern layer and a green pattern layer, a light source that emits blue light can be used. In such a case, the red quantum dot particles emit red light, the green quantum dot particles emit green light, and the transparent pattern layer emits blue light as it is and appears blue.

Manufacturing example : color conversion layer manufacturing

Each of the self-luminous photosensitive resin compositions prepared in the above examples and comparative examples were applied on a 2 × 2 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. Then, ultraviolet rays were irradiated onto the thin film. At this time, the ultraviolet light source was irradiated with an exposure dose of 40 mJ/cm2 (365 nm) in an atmospheric atmosphere using an ultra-high pressure mercury lamp (product name: USH-250D) manufactured by Ushio Denki Co., Ltd., and no special optical filter was used. The ultraviolet irradiated thin film was developed with a KOH aqueous developing solution of pH 12.5 using a spray developer for 60 seconds and then heated in a heating oven at 220°C for 20 minutes to prepare a pattern. The thickness of the self-luminous color conversion layer pattern prepared above was 2.0 μm.

Experiment example 1. Luminous intensity

In the above production example, except that the thickness of the color conversion layer was adjusted to 3.0㎛, each color conversion layer pattern manufactured with the same configuration and method was measured using a quantum efficiency meter (QE-1000, manufactured by Otsuka Corporation), respectively. The luminescence PL for the coated substrate was measured, and the luminescence intensity at the λmax wavelength is listed in Table 2 below.

It can be judged that the higher the measured luminescence intensity, the better the luminance characteristics.

Experiment example 2. residue evaluation

Each of the self-luminous photosensitive resin compositions prepared in the above examples and comparative examples 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. Afterwards, 50 mJ/cm ² ultraviolet rays were irradiated through front exposure without a photomask, and the film thickness of the formed pattern was measured using a film thickness measuring device (DEKTAK 6M, manufactured by Veeco). The substrate on which the thickness measurement was completed was developed by immersing it in a KOH aqueous developing solution at pH 10.5 for 80 seconds, and then visually inspected to see if any self-luminous photosensitive resin composition remained in the non-exposed area. At this time, the evaluation criteria for residue evaluation are as follows, and the results are shown in Table 2 below.

○: When no residue remains.

△: When remaining above 0% but below 20%

×: When more than 20% remains

Experiment example 3. Surface hardness

Referring to Table 2 above, in the case of Examples 1 to 8 that satisfy all the configurations of the present invention, the luminous intensity is superior to that of Comparative Examples 1 to 3 that do not satisfy any of the configurations of the present invention, and the residue It was confirmed that the occurrence of was reduced and the surface hardness was excellent.

Looking more specifically, in the case of Examples 1 to 8 containing any cardo-based compound compared to Comparative Examples 1 to 3 that do not contain any cardo-based compound, the luminous intensity is improved, the generation of residue is suppressed, and the hardness is lower. Improvement could be seen.

In addition, even if the same cardo-based compound is included, when a perylene bisimide-based fluorescent dye is further included (Examples 1 to 6), the luminous intensity is higher than when a general fluorescent dye is included (Examples 7 and 8). It was confirmed that the luminescence intensity was the best when cardo-based monomers were used (Examples 3 and 4) even when perylene bisimide-based fluorescent dye was included, and when cardo-based monomers and cardo-based resins were mixed, the luminous intensity was the best. It was confirmed that the cases (Examples 5 and 6) had superior luminous intensity than the cases where the cardo-based resin was used alone (Examples 1 and 2).
