Description

  The present invention relates to a silicon-containing resin composition, a silicon-containing resin film, a silica film, a light-emitting display element panel, and a light-emitting display device.

  Conventionally, extremely small particles (dots) formed to confine electrons are referred to as quantum dots, and application studies have been made in various fields. Here, the size of one quantum dot is several nanometers to several tens of nanometers in diameter, and is composed of about 10,000 atoms.

  Such a quantum dot can change the color (emission wavelength) of emitted fluorescence (wavelength conversion) by changing its size (changing the band gap). For this reason, in recent years, studies on applying quantum dots to display elements as wavelength conversion materials have been earnestly performed (see Patent Documents 1 and 2).

In addition, various optical light-emitting elements and application of optical films including quantum dots in display elements have been studied. As such an optical film, for example, an optical film in which quantum dots are dispersed in a matrix made of a silicon-containing resin such as polydimethylsiloxane has been proposed (see Patent Document 3).
For example, in an element that displays an image using light emission of a light source such as a liquid crystal display element or an organic EL display element, when light rays emitted from the light source are transmitted through an optical film including quantum dots, green light with high color purity is obtained by wavelength conversion. Since the red light can be extracted, the reproduction range of the hue can be expanded.

However, when a film including a matrix made of a silicon-containing material such as siloxane resin or silica and quantum dots dispersed in the matrix is formed, if the film is thick, a crack is generated in the formed film. There is an easy problem.

For this reason, when using an optical film containing quantum dots in a matrix made of a silicon-containing material, it is necessary to reduce the film thickness of the optical film, and the design of the optical film and various devices equipped with the optical film are remarkably different. There are limited issues.
For example, when manufacturing an optical film that is somewhat thick, it may be necessary to laminate a number of thin optical films in order to obtain an optical film without cracks. In such a case, the manufacturing cost of the optical film is high due to the complexity of the laminating operation.

In addition, in an optical film including quantum dots, in order to suppress scattering of luminance lines incident on the film, it is desired to disperse the quantum dots well to ensure a certain distance between the quantum dot particles.
However, when forming an optical film containing quantum dots in a matrix made of a silicon-containing material, depending on the composition of the composition used to form the optical film, it may be difficult to disperse the quantum dots in the film. is there.

The method for forming the coating film is not particularly limited. For example, the silicon-containing resin composition is applied by a method such as a spray method, a spin coating method, a roll coating method, a dipping method, or a dropping method to form a coating film on the substrate.
The thickness of the coating film is not particularly limited. Typically, the film thickness of the coating film is adjusted so that, for example, a silicon-containing resin film having a film thickness of 2 μm or more, preferably 5 μm or more is formed. The thickness of the coating film is preferably adjusted so that a silicon-containing resin film having a thickness of 2 to 300 μm, more preferably 30 to 200 μm, and even more preferably 75 to 150 μm is formed. A film having a film thickness of 5 μm or more, further 30 μm or more can be formed by adjusting the solid content concentration of the silicon-containing resin composition or an additive which is an optional component.

  For example, when a thick silicon-containing resin film having a thickness of about 2 to 300 μm is produced, cracks are likely to occur in the film when the solvent (S) is removed from the coating film. However, when the silicon-containing resin composition contains the aforementioned predetermined solvent (S), generation of cracks when removing the solvent (S) is suppressed.

After curing by exposure, the silica film patterned according to the shape of the mold can be obtained by peeling the mold.
The patterned silica film may be formed by a printing method. Examples of the printing method include an inkjet method and a screen printing method. After the silicon-containing resin composition is arranged in a pattern by a printing method, a patterned silica film can be obtained by exposure and / or heating or baking.

[Examples 1 to 12 and Comparative Examples 1 to 4]
Each of the types and amounts (parts by mass) of the silicon-containing resin shown in Table 1, the quantum dots, and the solvent were uniformly mixed to obtain silicon-containing resin compositions of Examples and Comparative Examples.
Using the obtained silicon-containing resin composition, tests for crack resistance and dispersion stability were performed according to the following methods. These test results are shown in Table 1.

(Crack resistance evaluation)
On the sample substrate, each silicon-containing resin composition shown in Table 1 was applied using a spin coater to form a coating film having a thickness capable of forming a 5.0 μm-thick silica film. After pre-baking the coating film at 100 ° C. for 2 minutes, the coating film is baked at 350 ° C. for 30 minutes using a vertical baking furnace (TS8000MB, manufactured by Tokyo Ohka Kogyo Co., Ltd.) to form a silica film having a thickness of 5.0 μm. Got. The surface of the formed silica film was observed using an optical microscope to confirm the presence or absence of cracks. The case where a crack was not confirmed was determined as good (◯), and the case where a crack was confirmed was determined as defective (×). The evaluation results are shown in Table 1.

(Dispersion stability evaluation)
The average particle diameter of the quantum dots in the obtained silicon-containing resin composition was measured using a dynamic light scattering particle size distribution analyzer LB-500 manufactured by HORIBA. The measured average particle size was defined as the dispersed particle size. A smaller dispersed particle size means that the quantum dots do not aggregate and the dispersibility is better. Regarding dispersibility, a case where the dispersed particle size was 8 nm or less was determined as good (◯), and a case where the dispersed particle size was greater than 15 nm was determined as poor (×). The evaluation results are shown in Table 1.

According to Table 1, when the silicon-containing resin composition contains a solvent having a structure represented by the above formula (S1) together with the quantum dots, production of a film in which the generation of cracks is suppressed and the quantum dots are well dispersed is produced. I understand that I can do it.
On the other hand, when the silicon-containing resin composition contains quantum dots but does not contain a solvent having a structure represented by the formula (S1), cracks are likely to occur in the produced film, and well dispersed quantum dots are obtained. It turns out that it is hard to form the film containing.
