[2] mensuration (embodiment 5～16 and comparative example 3～6) of voltage retention based on liquid crystal and ion concentration

(indium doping stannum oxide closes to use spinner setting speed (300rpm～700rpm) to have ITO at whole evaporation Gold) electrode glass substrate (EHC evaluation glass ITO full version (beta) MN-1392) on be coated with colored resin composition, make The thickness obtaining coated film is 2～3 μm (thickness after heat cure is of about 2 μm), and described colored resin composition comprises embodiment And the dyestuff of comparative example and making with above-mentioned ratio and composition, by the hot plate prebake 3 minutes of 80 DEG C, then in vacuum chamber It is dried 1 minute.

Then, use high-pressure mercury-vapor lamp, photomask is implemented, with 62mJ/cm in the periphery as electrode²Light exposure to painting Film exposure comprises the lonizing radiation 30mW of each wavelength of 303nm, 313nm, 334nm, 365nm, 405nm and 436nm, and then 200 Solidify (hereinafter also referred to as " solidification temperature ") after carrying out at DEG C 60 minutes, make curing of coating, obtained the blue picture of liquid crystal evaluation Element substrate (hereinafter also referred to as " resist film ").

With the warm water of water and 45 DEG C to define blue pixel substrate and only by ITO electrode evaporation for the electricity of shaped After electrode substrate (EHC evaluation glass SZ-B11MIN (B) MN11396) is carried out, it is dried in the baking oven of 105 DEG C, with mixed Close after having the sealant of bead of 5 μm to fit (gap is 5 μm), the baking close annealing 2 hours of 180 DEG C, obtaining Box in inject liquid crystal MLC-7021-000 (manufacture of Merck company), having made electrode area is 1cm²Liquid crystal cell.

Then, utilize liquid crystal evaluation of physical property system 6254 type (TOYO Corporation manufacture), determine at 25 DEG C The voltage retention of liquid crystal cell.Now apply voltage be 5.0V rectangular wave, measure frequency be 60Hz, 2Hz and 0.6Hz.This In described voltage retention is commonly known area ratio and 2 kinds of method for expressing of voltage ratio, have employed area ratio in this application Value (area surrounded to voltage trace and the voltage zero level of 16.7 milliseconds (examples of 60Hz) after 0 millisecond is relative to by 0 The voltage of millisecond keeps observation time 16.7 milliseconds (in the situation that 60Hz measures), observation time (to measure at 2Hz for 0.5 second Situation) or 1.67 seconds (situations of 0.6Hz) and the area ratio that obtains).

Ion concentration uses the device identical with voltage retention to be determined.Apply frequency 0.1Hz, the three of ± 10V Angle ripple, is output calculating the form of waveform of hour change of electric current.In waveform, the direct peak of liquid crystal advances with only The above-mentioned box of liquid crystal measures, and then, is measured the liquid crystal cell of each example.About liquid crystal direct occurred in ion waveform Peak and foreign ion peak and foreign ion density seek method, shown in Figure 2.

For voltage retention, it is preferably more than 85% at 60Hz, is preferably more than 25% at 2Hz, is more preferably More than 30%, more preferably more than 60%, particularly preferably more than 80%, preferable voltage retention is more than 90%.

It addition, the voltage retention of below 2Hz is the characteristic extremely sensitive to ionic impurity.The voltage of this below 2Hz Conservation rate wants intervention of coupled ion etc. and the ion concentration measurement result (direct peak current/foreign ion of ion concentration, liquid crystal Peak current), the behavioral observation of voltage retention under 60Hz and liquid crystal consider its preferred scope.

Additionally, the voltage retention under 0.6Hz is affected more notable by ionic impurity.This is because, 0.6Hz's In the case of, the movement in liquid crystal of the foreign ion on resist film surface is the most abundant, and the time measuring change in voltage is the longest.

By measuring ion concentration, it is appreciated that the impact of the ionic impurity deriving from resist film.That is, to cation In the case of side and anion side apply voltage, represent in either side it is all that ion concentration is the highest, comprise in liquid crystal Ionic impurity, comprises and hinders factor liquid crystal cell applying voltage and hindering the voltage of liquid crystal cell to keep.That is, ion is close Spending the least, electrical characteristics are the best.It should be noted that only in the case of liquid crystal, ion concentration is 0nC.

Liquid crystal evaluation result is summarized in table 4 (colored resin composition of table 1) and table 5 (coloured composition of table 2).

It should be noted that in table, voltage retention refers to, than liquid crystal for " cannot quantize because of current leakage " Response speed short time, namely apply after voltage in the time of less than 1 millisecond, voltage is decreased below 2V, therefore, liquid The phenomenon that voltage during brilliant box work is not applied on liquid crystal cell, electrical characteristics are significant lower.

It addition, ion concentration refers to for " cannot measure because of current leakage ", it is " because of current leakage in voltage retention Cannot measure " box in, electrical characteristics are significant lower, therefore can not measure ion concentration exactly.

" ion concentration is too high to measure " refers to, owing to there is current leakage, liquid crystal is not responding to, and therefore liquid crystal is straight Connect peak not embody in ion concentration, and, owing to the electric current produced is excessive, quasi-molecular ions is capped and cannot distinguish, beyond The ion concentration determination limit of device, represents that electrical characteristics are low.

As shown in table 3, the brightness using the pixel of the colored resin composition formation of the present invention is high, is good blueness picture Element.It addition, as shown in table 4 and table 5, by the blue pixel substrate (resist film) of the colored resin composition employing the present invention The voltage retention of this liquid crystal cell formed is the highest, and ion concentration is little, has good electrical characteristics.Particularly 200 DEG C such Temperature is slightly lower as the solidification temperature of resin combination, and ionic composition is in liquid crystal or on the boundary of liquid crystal Yu resist film Face dissolution, evaluates characteristic for liquid crystal and there is disadvantageous tendency.Even if using 200 DEG C of such slightly lower solidification temperatures, by having The ion concentration having the liquid crystal cell that the resist film of embodiment compound formed is the lowest, compared with comparative example, exists ionic miscellaneous The repressed tendency of dissolution of matter.Its result, voltage retention is high, is good.Particularly, for comprising the chemical combination of dyestuff B For the colored resin composition (embodiment 6,8,10,14) of thing, its ion concentration is the highest also below 1nC, the electricity under 0.2Hz Pressure conservation rate has exceeded 85%.I.e., it is known that its electrical characteristics are good and voltage retention is the highest.

As previously discussed, there is the light filter of the pixel using the colored resin composition of the present invention to be formed and comprise The liquid crystal indicator of this light filter and organic EL display are high-quality.

With reference to specific embodiment, the present invention is described in detail, but those skilled in the art should understand that It is, in the case of the spirit and scope of the invention, various change or correction can be carried out.The application was based on 2012 Japanese patent application (Patent 2012-077457) that March 29 proposed and complete, its content is as with reference to being introduced in this Shen In please.
