Description

Colored resin composition, colour filter and liquid-crystal display
The application is that application number is 200480009124.0, the applying date is on January 16th, 2004, denomination of invention is divided an application for the application of " colored resin composition, colour filter and liquid-crystal display ".
Invention field
The present invention relates to a kind of colored resin composition and its preparation method, colour filter and liquid-crystal display.More specifically, the present invention relates to a kind of colored resin composition, it has good transmitance, has pattern adhesivity good during developing, develops the back at the residual seldom resistates of image-region and have dry and hard generation of reduction during by the die head coating at the die lip end; The invention still further relates to colour filter with the pixel that forms therein with this colored resin composition; With the liquid-crystal display that this colour filter is housed.
Background technology
As the method for the colour filter that is used to produce liquid-crystal display or its analogue, known pigment dispersion usually, dyeing, galvanic deposit and printing process.Wherein, consider spectral response curve, weather resistance, pattern form and tolerance range, the most generally adopt pigment dispersion method with average good characteristic.
Pigment dispersion method generally carries out according to following program.At first, use metal optical screen film such as chromium or chromic oxide on transparent carrier such as glass substrate, to form the fast black base thing.The colored resin composition (below can be described as " color resist ") that for example wherein is dispersed with red pigment is applied to the whole surface of gained substrate by spin coating or similar approach.Through photomask exposure, developing then obtains red pixel with this substrate.In a similar way, by coating, exposure and develop formation blueness and green pixel.As a result, form three kinds of pixels.Because there is concave part in the fast black base thing place between two kinds of pixels,, there is this surperficial trend of polarization by filming with transparent resin such as Resins, epoxy or acrylic resin covering surfaces and outside forming thus.Yet, always do not form outer filming.Go up sputter or vacuum moulding machine (when when not being provided with outside, filming on pixel and fast black base thing) by filming outside, formation nesa coating such as ITO (tin indium oxide).
In recent years, also usually adopt above-mentioned colo(u)rant dispersion method to form the fast black base thing.More specifically, wherein be dispersed with the colored resin composition (can be described as below the said composition " black resist) of black pigment, then exposure and developing by coating.
Along with the marked improvement in the nearest technical renovation, needed to develop the colour filter that has than high permeability and higher concentration.The colour filter that has a high permeability for formation must improve the dispersity of coloured material.For satisfying this requirement, the nitrogenous dispersion agent with good dispersion energy becomes welcome.The colour filter that formation has high permeability and high density requires to improve the concentration of coloring material in colored resin composition, and this also requires to improve the concentration of nitrogenous dispersion agent.Yet, only use this dispersion agent can not obtain enough liquid stabilisings.Except that this problem, flavescence takes place during the heating steps that forms colour filter, therefore reduce the pixel transmission.Colored resin composition is generally by the preparation of two steps, and promptly tinting material and dispersant are with blended steps such as the step of disperseing this mixture and dispersion agent and solvent, binding agents.As the resin glue that will be mixed in the colored resin composition, known use has the resin (for example WO96-23237) that adds to the structure of the carboxy moiety acquisition that contains carboxy resin by the unsaturated compound that will contain epoxide group.The problems referred to above can not overcome fully by this photosensitive resin composition.
For liquid-crystal display, there is the trend that colour filter and structure cell between the relative substrate are narrowed down, with satisfied demand to the quick response that is suitable for the film indicating meter.This means the amount of liquid crystal that reduces every cellar area.
When the pigmentary resin composition comprises a large amount of nitrogenous dispersion agent, after forming liquid crystal cells, it takes place go in the liquid crystal through wash-outs such as ITO films, cause reducing the problem of liquid crystal voltage conservation rate.In addition, every as mentioned above structure cell area amount of liquid crystal reduces with corresponding acceleration, and this further reduces voltage retention.Voltage retention reduces and allegedly to cause display defect as showing inhomogeneous and image lasting (for example open 2000-292920 referring to the Japanese Patent spy and the Japanese Patent spy opens 2000-311228), this have for expectation highly see through, the liquid-crystal display of high density and response fast is serious problems.
Be to solve the problem of non-uniform of indicating meter, propose to be higher than the dispersion agent of the temperature-20 ℃ when forming pigmented layer as the method that is contained in the dispersion agent in the colored resin composition with having decomposition temperature.The decomposition temperature of definition is the extraction quantity of organic impurity when the colored resin composition that contains dispersion agent by heating the forms pigmented layer Heating temperature (for example opening 2000-171784 referring to the Japanese Patent spy) when becoming 100ppm in this suggestion.
Yet, in aforesaid method, use the dispersion agent of nitrogen atom to damage voltage retention sometimes and make demonstration inhomogeneous.
For forming the high density colour filter, the concentration of coloring material in colored resin composition must improve.This causes the relative quantity reduction that image is formed the component of performance such as photosensitivity and solvability contribution, the result, make colored resin composition lose image and form performance, said composition had originally or promoted undissolved colored resin composition to remain in non-imaging region after development.The resistates that do not dissolve in this non-pixel region on substrate not only causes transmitance and contrast gradient with the colour filter of this resin formation to reduce, and damages sealing property in the step subsequent step is caused disadvantageous effect because of causing ito thin film to peel off or form at liquid crystal cells.
As the measure that overcomes these problems, proposed that molecular weight is not more than 1000 organic carboxyl acid compound and added method (for example, referring to patent gazette No.3293171) in the colored resin composition.This method is effective by the residual quantity that use is used for the not dissolved substance of some colored resin compositions that the resin glue of dispersion staining pigment obtains for the back of reduce developing in non-pixel region.
The various new technologies of colour filter have been proposed to be used to form.Form in the step in various pixels,, it is evenly coated in by spin coating carries out the resist-coating step on the substrate then generally by resist is added dropwise to substrate center.Raise because the resist consumption increases with substrate size, be applied to the restriction (for example motor power) of the very big device mode on the spin coater simultaneously, therefore developed the coating technique that uses the die head coating recently, and some of them have dropped into actual use.
Resist has been used to produce floppy disk (trade mark) through the coating technique of die head coating usually, and this technology generally is fit to coating fluid such as resist are applied to medium such as polymeric film continuously.
On the other hand, in single colour filter coating, the painting erosion resistant agent interruption is carried out, and therefore repeats wetting and dry at the die lip terminal portions.When wherein having with the colored resist of high density dispersive pigment or black resist when the terminal portions of die lip is dry, because the pigment caking appears in pigment concentration remarkable increase sometimes.This caking sticks to the die lip end, when resist once more when it injects, it falls and is transferred on the substrate from the die lip end.It is not easy to remove and still remain on the substrate until final step in subsequent step.This caking becomes a reason of color filter pixel defective and damages its quality.Must avoid frequently this undesirable phenomenon taking place, because it has reduced the productivity of colour filter.
Summary of the invention
