摘要： PROBLEM TO BE SOLVED: To suppress the degradation of liquid crystal even in the case that a defect is generated in a protective insulation film on an electrode by providing an organic material between at least one electrode in an electrode group and an alignment control layer. SOLUTION: A TFT substrate is immersed in a polyamino resin solution together with a counter electrode and a DC voltage is applied so as to turn the electrode on the TFT substrate to a negative polarity to the counter electrode. By executing such a process, the part where the defect of an insulation film 4 or the protective insulation film 7 is generated on the electrode is covered with the electrode where the polyamino resin is formed as the organic material layer 10. Thus, even in the case that the defect of the insulation film 4 or the protective insulation film 7 is generated on the electrode, the electrode and the liquid crystal are not brought into physical contact by the organic material layer 10 formed at a defective part. As a result, the generation of ionic impurities by electro-chemical reaction is suppressed and the effect of suppressing the generation of luminance irregularities is obtained.

摘要： PROBLEM TO BE SOLVED: To obtain a composition which can form a printed resin film easily patterned without a step of photolithography by using each of a low-molecular-weight portion having a specified molecular weight distribution peak and a high-molecular-weight portion having a specified molecular weight peak as the resin component of a polyimide or of a precursor thereof. SOLUTION: The peaks of the low-molecular-weight and of the high-molecular-weight portion are 1,000 to below 10,000 and 10,000 to 1,000,000, respectively. The polyimide or the precursor thereof is desirably one prepared by reacting an aliphatic or alicyclic tetracarboxylic acid dianhydride with a diamine compound. The composition desirably has a solid matter concentration of 7-60 wt.% and a viscosity of 30-1,000 mPa.s. The transmittance to light at a wavelength of 400-800 nm is desirably 90% or above when measured on a film having a thickness of 0.1-3 μm. The composition can easily form a resin film having a uniform thickness of 0.1-3 μm, and the formed film is useful as an insulation film for semiconductors, a protective film for liquid crystal color filters and, after surface rubbing, is useful as a liquid crystal alignment film or a liquid crystal protecting/alignment film.
