T! 1 By destroying the micelles through deoxidation, the anode W
I have invented a method for manufacturing color filters by forming a pigment particle film on top of the i-layer (Patent Application 1986-1).
75610). However, since the dye thin film is a deposited film of dye particles, it is merely physically adsorbed onto the substrate.
In addition, since the pigment particles are only physically adsorbed to each other, when used as a color filter for an LCD panel such as an LCD TV, some parts of the pigment particles may peel off when powerful ultrasonic cleaning is applied during the process of making the panel. Some processing may be done by rubbing or rubbing necessary for liquid crystal alignment treatment.
Problems related to the adhesion of the film, such as separation, occurred.

However, in this case, if the coating resin is thick, the pigment particle film will have sufficient IQ and the adhesion will improve.One of the features of this color filter is that the electrodes used for electrolysis can be used as they are for driving the liquid crystal. The benefits of this will not be utilized. In other words, if a thick resin film is formed on the dye thin film, when driving the liquid crystal, in addition to the loss of applied voltage due to the dye thin film, there will be a loss of applied voltage due to the resin film, resulting in a decrease in the liquid crystal drive voltage and a decrease in liquid crystal drive performance. There is a problem of putting it away.
