Description

Photosensitive composition is shown using the colour filter and image of its manufacture Device
Technical field
The present invention relates to photosensitive composition, utilize the colour filter and image display device of its manufacture.
Background technology
Colour filter is widely used in image display device etc. as photographing element, liquid crystal display device, therefore it is applied Range is hastily expanding.The colour filter used in color liquid crystal display arrangement, photographing element etc. is usually manufactured by the following： It is equably coated with containing each form and aspect with red green and cyan using spin coating on the substrate for form black matrix pattern When colorant photosensitive composition after, be thermally dried (below also be sometimes referred to as pre-fired), to being formed Film be exposed, develop, be further heating and curing (below also be sometimes referred to as then be burnt into) as needed, for colors The operation is repeated, forms assorted pixel.
Photosensitive composition is containing colorant and the photosensitive polymer combination that colours, can be used as being used for shape At the material for the colored pattern for constituting colour filter.Wherein, colour filter is to be built in color liquid crystal display arrangement, in order to scheme display The optical element for using as coloration or being built in photographing element, being used to obtain coloured image.
Recently, for the energy-saving technology of colour liquid crystal display device, the higher colour filter of brightness is needed.Usually, colour filter utensil Have the tendency that the more thin then brightness of film thickness is higher.At this point, in order to ensure the color reproduction of height, it is necessary to realize high pigment levels.But The high concentration of pigment makes the bin stability of anti-corrosion agent composition, coating further decrease, therefore with abundant performance The making of colour filter becomes difficult.
In order to realize these purposes, the application of dyestuff is had studied.It is more but generally compared with the situation for applying pigment Reliability and the low problem of contrast occurs.The technology existed when it is therefore desirable to develop for solving the problems, such as using dyestuff.
KR published patent the 2014-0115990th is related to coloured composition, colored cured film and display element, open Related with coloured composition content, it includes selected from xanthene compound, polymethine chemical combination which, which is comprising (A), Colorant, (B) binder resin and (C) polymerism of at least one kind of compound in object, coumarin compound and compound The coloured composition of compound also includes (D) transistion metal compound (but, not including (A) ingredient).
KR published patent the 2015-0101934th is related to coloured composition, colored cured film and display element, open Content in relation to coloured composition, the coloured composition are the coloring compositions for including (A) colorant and (B) polymerizable compound Object, (A) colorant include the polymer with the position for sending out fluorescence and the position for absorbing the fluorescence.
But it is above-mentioned in the prior art, shown due to colour former as additive as transition metal or anthraquinone Distinctive color, so brightness and reliability may become unfavorable.
