Description

Color composition for color filter and color filter

Technical field

The present invention relates to the color composition for color filter used in the manufacture of the color filter that color liquid crystal display arrangement and color image sensor etc. comprise and possess the color filter of filter section and/or the black matrix" using its formation.

Background technology

Liquid crystal indicator has the structure clamping liquid crystal material and multiple pixel between 2 polaroids.In liquid crystal indicator, each pixel is applied voltage, makes the state of orientation of liquid crystal material change, make the polarization degree of the light by the 1st polaroid change, thus controlling to show image by the transmission light of the 2nd polaroid.

Liquid crystal indicator by arranging color filter between these 2 polaroids, it is possible to carries out colored display, thus using in television receiver, PC and monitor etc..

Color filter have by for preventing the colour mixture of transmission light, improve the photomask of trellis displayed contrast and black matrix" (following, BM) and the filter section of multiple color (being generally red, green, blue) arranged accordingly with pixel are arranged on the structure on the transparency carriers such as glass plate.Filter section is fine to a few micrometers～several 100 microns.In the arrangement of filter section, there is the arrangement (bar arrangement) of fine band (bar) the shape configuration with different form and aspect of more than two kinds, with the arrangement (triangle arrangement) etc. being arranged certain in length and breadth.Filter section and BM are by being coated with coloured composition, and make it be typically in more than 180 DEG C, be formed preferably in being dried under the high temperature of 230 DEG C.

In color liquid crystal display arrangement, by being deposited with or sputter the transparency electrode formed for driving liquid crystal on color filter, then it is formed on the alignment films for making liquid crystal orientation in a certain direction.In order to fully obtain the performance of these transparency electrodes and alignment films, it is generally required to more than 180 DEG C, preferably in carrying out its formation under the high temperature of more than 230 DEG C.Therefore, at present, as the manufacture method of color filter, main flow is become using the pigment of light resistance, excellent heat resistance as the method being referred to as pigment dispersion method of coloring agent.

As the quality needed for color liquid crystal display arrangement, high image quality, low power consumption etc. can be listed, in order to realize these qualities, it is desirable to high brightness, high-contrast, high-resolution color filter.

Particularly in recent years from the view point of power consumption, the high brightness of color filter has become trend.

If using the color filter that brightness is high, then owing to the absorbance of light is high, it is possible to reduce the quantity of the backlight as light source, it is possible to suppress power consumption.

Conventional color filter is in red filter saves, diketopyrrolopyrrolecocrystals series pigments and anthraquione pigmentss etc. are combined, in green filter saves, CuPc or Phthalocyanine Zinc pigment are combined with nickel azo complex series pigments etc., in blue electric-wave filter saves, copper phthalocyanine pigments and diazine series pigments etc. are combined, it is possible to realize high brightness and wide color viewing area.But, require further high brightness as described previously for color filter.

In recent years, it is desirable to further high brightness, the colorant of dyestuff system gets most of the attention.Wherein triarylmethane system pigment such as the ton such as rhodamine pigment, eosin pigment system pigment, triphenyl methane etc. has dominance due to color characteristics, so being expected to as the material (referring for example to patent documentation 1,2) realizing high brightness.

But, make containing the pixel of above-mentioned pigment, measure colourity, after the high temperature drying at when pixel is formed 230 DEG C of result, luminance-reduction compared with before high temperature drying.For the colorant of dyestuff system, owing to thermostability is poor compared with the pigment used in the past always, so having the problem that cannot fully obtain high brightness because of heat treatment.If which imply the luminance-reduction that can suppress because heat treatment causes, then there is the leeway improving brightness further.
