Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blue color filter used in a display device such as a mobile terminal or an industrial measuring instrument, and an organic electroluminescence (hereinafter abbreviated as organic EL) device using the same.

[0002]

2. Description of the Related Art As one of methods for making an organic EL display multi-colored or full-colored, a color conversion system in which a fluorescent material that absorbs light in an emission range of an organic light-emitting body and emits fluorescence in a visible light range is used as a filter. Are disclosed in JP-A-3-15897, JP-A-5-258860, and the like. According to this method, the emission color of the organic light-emitting body is not limited to white, so that an organic light-emitting body with higher brightness can be applied to the light source, and for example, blue light can be converted into green light or red light using an organic light-emitting body that emits blue light. A color conversion method for wavelength conversion is disclosed in JP-A-3-152897.
It is described in JP-A-8-286033 and JP-A-9-208944. If a fluorescent conversion film containing such a fluorescent dye is patterned on a transparent support substrate with high definition, full-color light emission can be achieved even with low energy light such as near-ultraviolet light or visible light of an organic light-emitting body. Type display can be constructed.

In an organic EL device using a color conversion system having a color filter and a color conversion filter and an organic luminescent material as constituent elements, the heat resistance required in the manufacturing process of a color display and the weather resistance when used as a display. Properties, and for those requiring high-definition images, the mainstream is to use color filters prepared by the pigment dispersion method, and red in the photosensitive resin solution,
After finely dispersing a blue or green pigment with a particle size of 1 μm or less on a glass substrate, pixels are formed in a desired pattern by photolithography (Patent Publication 4-
No. 37987, Japanese Patent Publication No. 4-39041, etc.).

Improvements in color purity, saturation, and light transmission amount of color filters have been demanded, and conventionally, for the purpose of improving the light transmission amount, the content of a coloring pigment to a photosensitive resin in an image forming material has been increased. Has been adopted, or the formation film thickness of the pixel formed by the image forming material has been thinned. However, in these methods, the saturation of the color filter itself is reduced, the entire display becomes whitish and the vividness of the color necessary for display is sacrificed, and conversely, the saturation is prioritized to reduce the content of the coloring pigment. For example, the entire display will be dark, and the backlight intensity must be increased to ensure brightness.
There is a problem that the power consumption of the display is increased.

On the other hand, there is known a method of finely dispersing the particle size of the pigment particles to ½ or less of the coloring wavelength for the purpose of improving the light transmission amount (Hashizume Kiyoshi, coloring materials). (Journal of Japan, December 1967, p608), blue pigments have a shorter coloring wavelength than other red and green pigments, so further fine dispersion is required in this case, resulting in higher costs and stabilization after dispersion. Is a problem.

Further, as the blue pigment, copper phthalocyanine-based blue having a type, a type, and a crystal form of a type is widely used (Handbook of Color Material Engineering, edited by Color Material Association,
p333), when copper phthalocyanine blue of the type as a blue pigment is used alone in a color filter, its coloring power is low, and many pigments must be mixed with a photosensitive resin in order to exhibit the desired saturation. However, there is still a problem in the heat discoloration after forming the color filter and the adhesion with the glass substrate, and there is a problem that the amount of transmitted light with a wavelength of 600 nm or more is large and the color purity is lowered. .

On the other hand, when the type copper phthalocyanine blue is used alone as the blue pigment, it is possible to reduce the amount added to the photosensitive resin due to its excellent coloring power, but the desired saturation is obtained. When the amount of the pigment mixed is increased, the light-shielding property at 365 nm, which is the curing wavelength of the photosensitive resin, is increased, and the photocuring sensitivity is lowered, causing a problem of film flow during development and pattern flow.

Further, the mold copper phthalocyanine blue is
Since it is a greenish blue color, when it is used alone as a blue pigment, there is a problem that the deviation from the target NTSC hue becomes large. It is also known to use a pigment obtained by mixing copper phthalocyanine blue with dioxazine violet in a color filter (Japanese Patent Publication No. 6-95211, Japanese Patent Laid-Open No. 1-200353, Japanese Patent Publication No. 4-37987, etc.). Any one of the above three types of copper phthalocyanine blue and a dioxazine violet I.I. C. Pigment violet 23 is used to suppress the light transmission of 500 to 550 nm and improve the color purity, but the desired blue region 420 to
There is a problem that the light transmission at 500 nm is suppressed and the brightness when used as a display is reduced. Further, when it is used as a display, the light transmittance of the blue region is suppressed to 70 to 80% compared to the other color regions by the polarizing plate, so it is required to improve the light transmission amount of the blue filter. .

/ Ag (weight ratio 1:10), and by mask vapor deposition, a stripe pattern perpendicular to the anode line with a pitch of 0.33 mm and a gap of 0.05 mm was formed.

After the film formation of each layer is completed, the organic EL device 10 is formed.
0 was taken out from the vapor deposition apparatus, and sealed in a nitrogen atmosphere with a sealing glass and a UV adhesive so that the element did not come into direct contact with the atmosphere (not shown). The produced organic EL element 100 emits blue light having a peak at a wavelength of 470 nm. Example 2 In the formation of the blue color filter in Example 1, the structural formula (5) was used instead of the second dye used in Example 1.
An organic EL device was produced in the same manner as in Example 1, except that 1 part by weight of the dye shown in 2 was added to 100 parts by weight of the solid content of the transparent photopolymerizable resin as the second dye.

[0028]

[Chemical 10] Example 3 In the formation of the blue color filter in Example 2, except that the nickel complex represented by the structural formula (6) was added as a quencher in a ratio of 0.3 mol with respect to 1 mol of the first dye. A blue color filter coating liquid was prepared in the same manner as in 2, and an organic EL device was similarly obtained.

[0029]

[Chemical 11]

[0030]

Comparative Example 1 A blue color filter coating material was prepared in the same manner as in Example 1 except that copper phthalocyanine blue was used as a pigment instead of the first dye and the second dye used in Example 1. did. The amount of the pigment added was adjusted so that the light transmittance at a wavelength of 470 nm was the same as in Example 1 when the blue color filter was formed to have the same film thickness as in Example 1.

[0031]

[Evaluation] The following evaluations were performed on the produced samples.
The evaluation results are shown in Table 1. Here, the CIE chromaticity was evaluated by causing the produced device to emit light. A chromaticity meter (MCPD-1000 manufactured by Otsuka Electronics) was used for the measurement. As for the contrast, the fluorescent light (1000 lx) is slanted 45 degrees to the display surface of the device.
The contrast when illuminated from ° was compared. The values in the table are relative values when the result of the comparative example is 1.0, and the value is 1.0
If it is above, the contrast is improved. For the transmittance, an absorption spectrum was acquired using an absorptiometer (UV-2100PC manufactured by Shimadzu Corporation), and wavelengths of 470 nm and 5
The light transmittance at 10 nm was compared.

[0032]

[Table 1] As shown in Table 1, the light transmittance at 510 nm when the films were formed with the same light transmittance at 470 nm,
It is higher in the example than in the comparative example. This means that the color filter of the example has a higher light-shielding property in the wavelength range that reduces the purity of blue color, as compared with the color filter of the comparative example. Further, in the color filter of Comparative Example in which the pigment is dispersed in the binder, scattering is likely to occur in the color filter and at the interface. On the other hand, in the color filters of the examples, it is considered that the dye is completely dissolved in the binder, the transparency is high, and the contrast is high.

[0033]

According to the present invention, it is possible to provide a blue color filter having a high blue purity and a high transmittance and a good contrast, which is suitable for an organic EL display and an organic EL element using the same.
