Description

Colored filter green coloring composition

Technical field

The present invention relates to using the organic EL(electroluminescence of white for having) element is as the colored filter green coloring composition of the formation of the colored filter of the colour display device of light source.

Background technology

Recently, the display device of nearly all televisor, computer, mobile phone etc. is all occupied by liquid crystal colour disply gradually.For the colored filter of liquid crystal colour disply, conventionally there is transparency carrier, be formed on the dyed layer that the trichromatic coloring mode in transparency carrier Shang You red pixel district, green pixel district, blue pixel district forms and be formed on the light shielding part (black matrix) on transparency carrier in order to distinguish each coloring mode.These red pixel districts, green pixel district, blue pixel district are that the epithelium that makes to be dispersed with the synthetic resin of the good organic pigment of thermotolerance, photostability is arranged on the structure on substrate, as organic pigment, can use red, green and blue organic pigment of all kinds.

As the backlight in this liquid crystal colour disply, have the type of use cold-cathode tube (cold-cathode tube), use the light emitting diode of inorganic material type, use the type of white organic EL etc.Secondly, with the backlight of the light emitting diode of cold-cathode tube, inorganic material from excellent display performance, with the mating and then the aspect of the permanance of backlight of colored filter, the backlight of setting bright line spectrum (bright line spectrum) is more, with respect to this, in having used the emission spectrum of the backlight of white organic EL (emission spectrum), from properties of materials, near 420～430nm, there is no peak, near 460nm and near 600nm, having peak.In addition, contrast light source in the past, owing to thering is the broad peak of globality, so even the wavelength side higher than 460nm, even near 500nm, brightness also uprises.

On the other hand, when use has adopted the backlight of white organic EL, as the color characteristic (x in the XYZ colour system of the green filter joint (filter segment) of liquid crystal colour disply, y, Y), by spectrophotometer (company of Shimadzu Seisakusho Ltd. system, UV-2500PC, 2 ° of visual field Huo great mound electronics corporation systems of illuminant-C, LCF-100 type, while micro-spectral analyzer) measuring, needing x is the scope (scope that Toyo Ink is 0.180≤x≤0.225) of 0.180≤x≤0.250, y is the scope (scope that Toyo Ink is 0.650≤y≤0.715) of 0.650≤y≤0.715, Y is higher.

In relation as above, for the wavelength characteristic of backlight of light emitting diode with using cold-cathode tube in the past, inorganic material is consistent, the colored filter of the green filter joint formation material of design disperses anti-corrosion agent composition with viridine green, particularly, there are C.I. pigment Green 7, C.I. pigment green 36 etc., in the emission spectrum of backlight that has used white organic EL, become and can not obtain above-mentioned color characteristic value, there is the problem that can not directly utilize.

In order to address this problem, proposed and used the emission spectrum of backlight of white organic EL consistent, by specific viridine green and colored filter that yellow uitramarine forms, with viridine green, disperse the scheme (for example, referring to Patent Document 1) of anti-corrosion agent composition.

Yet while needing the performance of further colouring power, brightness etc. to improve when becoming, its countermeasure is just more urgent.

Table 1

Above-mentioned through micronize process pigment No.1～18 or the micronize as C.I. pigment yellow 185 processed without micronize process pigment No.19, have basic group polymer pigment dispersant, there is sulfonic pigment dispersion aids, alkali soluble resin (BMA/MAA multipolymer), optical polymerism compound, organic solvent (PGMEA) and mix according to the composition of table 2; use the zirconium oxide bead of 0.2mm Φ to use mixing 6 hours of paint conditioner, obtain pigment dispensing composition 1～26 for colored filter.

Table 2

Next, by pigment dispensing composition 1～26 for colored filter, BMA/MAA multipolymer, DPEHA, gorgeous good solid 369, PGMEA, after using homo-mixer to mix according to the composition of table 3, with the membrane filter of aperture 3 μ m, filter, obtain Pigments anti-corrosion agent composition 1～26 for colored filter.

Table 3

The colored filter of<embodiment 1～11 and comparative example 1～6 disperses anti-corrosion agent composition with viridine green>

According to the pigment ratio of table 4, by being selected from colored filter, with the composition of Pigments anti-corrosion agent composition 1～26, mix, the colored filter that obtains embodiment 1～11 and comparative example 1～6 disperses anti-corrosion agent composition with viridine green.

Table 4

(evaluation)

With viridine green, disperse anti-corrosion agent composition to gather respectively into vial the colored filter of embodiment 1～11 and comparative example 1～6, plug sternly, is evaluated its state after 7 days in room temperature preservation according to following evaluation criterion.Result is as shown in table 1.

A: tackify, sediment are all less than finding.

B: find that there is while vibrating gently and recover tackify, the sediment of degree originally.

C: also do not recover tackify, the sediment of degree originally even if find that there is strong vibration.

With viridine green, disperse anti-corrosion agent composition to use sol evenning machine (spin coater) to be coated on glass substrate the colored filter of embodiment 1～11 and comparative example 1,2,4,5.Next, at 100 ℃ of preliminary dryings (pre-bake), after 3 minutes, with high-pressure sodium lamp, expose, more further after 230 ℃, dry (post-bake) 30 minutes.Next, use spectrophotometer (company of Shimadzu Seisakusho Ltd. system, UV-2500PC, 2 ° of visuals field of illuminant-C) to measure the color characteristic (x, y, Y) of each resist of embodiment 1～11 and comparative example 1,2,4,5.In embodiment 1～11 and comparative example 1,2,4,5, the thickness during with colourity x=0.224, y=0.669, tries to achieve lightness Y.

According to the embodiment 1～11 as following example of the present invention, due to the favorable dispersibility of colored filter with the pigment of pigment coloring anti-corrosion agent composition, and the value step-down of Y, therefore the known colored filter as the organic EL light source of white possesses applicable optic character.

On the other hand, according to not using pigment yellow 185 to adopt the comparative example 2,3,5 and 6 of other pigment, even because x is identical with value and the embodiment of y, the value of Y is also high, so the colored filter that can not use as white organic EL light source is compatibly used.

In addition, according to the comparative example 1 and 4 of not using dispersing aid, resulting colored filter is insufficient by the dispersion stability of pigment coloring anti-corrosion agent composition, even if thereby find that there is strong vibration and also recover tackify, the sediment of degree originally.
