<p>PURPOSE:To obtain a production method of color filters with good productivity to control the spectroscopic characteristics with high precision. CONSTITUTION:A red pattern printing film (R), green pattern printing film (G) and blue pattern printing film (B) are formed by successively applying printing inks having higher content of coloring pigment on the picture element on a glass substrate 1. In this case, these printing films are formed so that the end of each film overlap with adjacent films to form 10mum overlap width. Then the films are heated to harden to obtain a color filter having color filter layers consisting of each printing films. By successively applying printing inks in an order from an ink having higher content of color pigment, and then the printing films are heated to harden, so that the changes of film thickness cheked by sampling during printing can be almost same. Thus, the film thickness and spectroscopic characteristics of filter layers of the color filter produced can be exactly estimated according to the result of sampling check.</p> |
