Description
Technical field
The present invention relates to pigment dispensing composition, photosensitive composition, colour filter and include the colour filter
Image display device.
Background technology
Colour filter is widely used in photographing element, liquid crystal display device etc., and application range is expanding rapidly.It is colored
Colour filter used in liquid crystal display device or photographing element etc. is generally as follows manufacture：In the substrate for being formed with black matrix pattern
It is upper to contain the photosensitive composition for being equivalent to red, green and blue colors colorants by spin coating even spread
Afterwards, heat drying (hereinafter, otherwise referred to as pre-fired), is exposed the film of formation, develops, further right as needed
Each color repeats to be heating and curing the operation of (hereinafter, being burnt into after otherwise referred to as), forms assorted pixel.At this point,
Vacuum drying (Vacuum dry, VD) process of the solvent removal process as resist can be carried out after coating immediately.
It, can be anti-by slit (Slit) coating method coating chromatic currently as one of main CF method for preparing substrate
Agent is lost, when being used as solvent removal more than previous vacuum (Vacuum) capacity to shorten by increase in VD processes after coating
Between VD production time per pieces (Tact time) time, thereby increasing productivity.But occur due to the decompression with high vacuum
The rapid draing of resist, thus can occur VD speckles (though VD speckles show as diversified shape, mainly with volcanic crater
The shape of speckle generates, therefore as long as no specifically mentioned, regards VD speckles and volcanic crater speckle as identical speckle and says
It is bright) etc. surfaces it is bad.It is therefore desirable to even if implement can be formed the highly sensitive of uniform film if the decompression of high vacuum
Color sensation photosensitive resin composition.
As for solution to the problems described above, VD speckles (volcanic crater can be inhibited using using high boiling solvent
Speckle) method, but there are problems that VD production time per pieces increase due to the evaporation rate of solvent is slow.
In addition, in recent years, due to the pixel for requiring colour saturation high, the pigment used in photosensitive composition
It is got higher with the content of carbon black, therefore mobility in drying is caused to be deteriorated and VD speckles (volcanic crater speckle) increase.
