Description

Grey photosensitive polymer combination, using its manufacture colour filter and include the colour filter The display element of device

Technical field

The colour filter manufactured the present invention relates to grey photosensitive polymer combination, using it and the display comprising the colour filter Element.

Background technology

Recently, display part, distribution are formed on the flexible substrate being made up of the plastics of flexible (flexible) raw material etc. Deng being attracted attention so as to be bent even if as paper and can also carry out the flexible display element that image shows.

The application of flexible display element is varied, is not only applicable to the monitor and television set of computer, and Personal Portable device is applied to, especially, organic light-emitting display device (Organic Light Emitting Display； OLED) with liquid crystal display device (Liquid Crystal Display；LCD it is) different, it is not necessary to light source in addition, therefore can be real The thickness of existing relative thin, in this respect, for flexible display element, in actively research organic illuminating element.

On the other hand,, must when being compared with present various display product for practically application flexibility display element Must be achievable panchromatic, power consumption must diminish, and also must easily be read even in outdoor.

In the sense that, organic illuminating element is due to realizing panchromatic possibility and low power consumption, quick Response speed advantage, therefore become as the most useful resource of the light source of flexible display element.With regard to present organic hair , it is necessary to for protecting organic illuminating element from oxygen and the encapsulating barrier (encapsulation of moisture influence for optical element Barrier) layer, also, in order to read (outdoor readability), it is necessary to Polarizer even in outdoor also easy (polarizer) to maintain high light dark ratio (contrast ratio).

But, if Polarizer of the application with hard characteristic, the flexibility reduction of flexible display element can be produced Shortcoming.If on the contrary, do not apply Polarizer, outer light transmissive enters after flexible display element, then secondary reflection and outgoing, simultaneously With the light colour mixture sent originally by organic illuminating element, the light dark ratio under external light source significantly reduces.

Thus, it is improved in positive research recently, is used as an example, KR published patent 10-2013- In No. 0134494, it is proposed that contain the colouring agent comprising green colourant and yellow colorants, resin glue and closing isocyanide Proposed in the ink composition of perester radical, KR published patent the 10-2013-0134498th containing comprising red stain and The ink composition of the colouring agent of green colourant, resin glue and blocked isocyanate base.But, in above-mentioned prior art In the case of, the range of choice of colorant is restricted when haveing the shortcomings that to realize high color reproduction, while the reality in various color region Existing deficiency, moreover, there is line defect and the machinability deficiency such as sapping in terms of patternability, so that in the technology Lasting improve is required in field.
