Color filter and process for producing the same

Abstract

There is provided a color filter which comprises a transparent substrate, a picture element part provided on the transparent substrate by the predetermined pattern of a plurality of colors with an ink jet system, a shading part provided on a border part of this picture element part, and a wettability-variable layer, in which the wettability can be changed, provided for forming the picture element part or the picture element part and the shading part.

         16 . The color filter according to  claim 15 , wherein the shading part in formed on the transparent substrate, the wettability-variable layer is provided on at least the shading part and on a picture element part forming portion which is a part on the transparent substrate, on which the picture element part is to be formed.  
     
     
         17 . The color filter according to  claim 16 , wherein a width of the picture element part formed on the wettability-variable layer is wider than that of an opening formed by the shading part.  
     
     
         18 . The color filter according to  claim 16 , wherein an ink-repellent convex part is formed on a surface of the wettability-variable layer provided on the shading part.  
     
     
         19 . The color filter according to  claim 18 , wherein a width of the ink-repellent convex part is formed narrower than that of the shading part.  
     
     
         20 . The color filter according to clam  15 , wherein the wettability-variable layer is formed on the transparent substrate and the picture element part and a shading part are provided at a position on this wettability-variable layer.  
     
     
         21 . The color filter according to  claim 15 , wherein the shading part is provided on the transparent substrate, and the wettability-variable layer is provided on a picture element part forming portion which is a part on the transparen substrate, on which the picture element part is to be formed and the picture element part is formed on the wettability-variable layer.  
     
     
         22 . The color filter according to  claim 14 , wherein the wettability-variable layer is provided on a border part of the picture element part.  
     
     
         23 . The color filter according to  claim 22 , wherein the shading part is formed on the transparent substrate, the wettability-variable layer is formed on the shading part and the picture element part is formed between the wettability-variable layers.  
     
     
         24 . The color-filter according to  claim 23 , wherein a width of the wettability-variable layer is formed narrower than that of the shading part.  
     
     
         25 . The color filter according to  claim 22 , wherein the wettability-variable layer is formed on a shading part forming portion which is a part on the transparent substrate, on which a shading part is to be formed, the shading part is formed on the wettability-variable layer, and the picture element part is formed between the shading parts.  
     
     
         26 . The color filter according to  claim 22 , wherein the wettability of the transparent substrate is less than 10 degrees as a contact angle with a liquid having a surface tension of 40 mN/m.
