Description
Technical field
The present invention relates to the resin-coated substrate and the manufacturing installation thereof of resin that use, that be coated with multiple color in the color filter that the electronic display unit colorize of LCD and so on is used (below also be referred to as " CF ") etc.
Background technology
According to Fig. 6 to Fig. 9, be the existing substrate that is provided with the resin bed of multiple color on the surface of example full-time instruction with above-mentioned color filter (CF).Fig. 6 is the step key diagram that adopts existing pigment dispersing manufactured substrate, Fig. 7 (a) is the key diagram that adopts 3 look CF of pigment dispersing method, (b) is the key diagram that adopts the 4 look CF that comprise light-proofness resin (black matrix (black matrix): hereinafter also be referred to as " BM ") of pigment dispersing method.Fig. 8 is the key diagram that adopts 3 look CF of strike, and Fig. 9 (a) is the key diagram that adopts the CF of existing 3 look print processes, (b) is the key diagram that adopts the CF of the existing 3 look print processes with BM.
In the past, the substrate that the surface is provided with the resin bed of multiple color was the manufacturing of CF, and using maximum is the pigment dispersing method.The cardinal principle situation of pigment dispersing method is: coating, drying, exposure, the step of developing of the photoresist (colored resist) by carrying out colorize repeatedly according to number of colours are made CF.
For example under the situation of 3 look CF 10a, as shown in Figure 6, need coating, drying, exposure, development step of carrying out every kind of color repeatedly as described below: (a) the resist r1 of the 1st kind of color of coating and dry on substrate; (b) the exposure e that is undertaken by the 1st kind of color mask m1; (c) the resin c1 to the 1st kind of color develops with dry; (d) the resist r2 of the 2nd kind of color of coating and dry; (e) the exposure e that carries out with the 2nd kind of color mask m2; (f) the resin c2 to the 2nd kind of color develops with dry; (g) the resist r3 of the 3rd kind of color of coating and dry; (h) the exposure e that carries out with the mask m3 of the 3rd kind of color; (i) the resin c3 to the 3rd kind of color develops and drying, because the pigment dispersing method has the multiple tracks step, thereby needs huge equipment investment.
Because (for example r1～r3) consumption is very big for resist in each road step, and major part wherein goes out of use as entraps globule, huge device, huge dust-free workshop, auxiliary facility (コ one テ イ リ テ イ one), waste liquor treatment equipment etc. constitute huge cost, and whether these can tackle the large substrate that promptly needs in the near future and be still a problem.
In addition, aspect the surface of CF, owing to be based on the dried lamination of each color, thereby as the 3 look CF10a of the red R among Fig. 7 (a), green G, blue B, and comprise (b) that shown in the 4 look CF 10b of black matrix (BM), shades of colour all presents unique surface configuration, can't obtain smooth surface, thereby produced the inequality of thickness of liquid crystal aspect with display, thereby cause showing uneven as liquid crystal.In addition, therefore coating thickness also increases, and becomes problem qualitatively.
Employing is carried out the CF 11 that the painted strike of electricity obtains to charged color resin, as shown in Figure 8, form ITO (Indium Tin Oxide, tin indium oxide) electrode 2 on substrate 1, electrode is selected, painted, drying is made by carrying out repeatedly according to number of colours.
Therefore, among strike,, and, display quality is descended in principle at the following surface forming electrode 2 of CF because the manufacturing step of ITO electrode 2 rises cost.In addition, can not form BM in principle, need adopt other unit when needing BM, production cost is risen.
