<p>PURPOSE:To improve the adhesion between insulation film and substrate and improve the transparency and direct current resistance of the display device by providing an insulation film composed of polyether sulfone on the electrode forming surface of substrates thereby forming the liquid crystal display device. CONSTITUTION:A methanol sulution containing 1 wt% of epoxy base silane is coated over the entire electrode forming surface of a substrate 1 which comprises forming electrodes 2 of specified patterns with tin oxide, indium oxide, etc. on its surface and is then dried for about 10 minutes at about 100 deg.C, whereby an underlying film 3 is formed. Next, the solution comprising dissolving 5 wt% of polyether sulfone to a mixed solvent of about 80 parts of cyclohexane and about 20 parts of dimethylformamide and further adding and mixing 25 wt% of methyl ethyl ketone is coated and is dried for about 15 minutes at about 160 deg.C then for 15 minutes at about 400 deg.C to form an insulation film 4, after which orientation treatment is applied after rubbing the surface through the use of a cotton cloth or the like. Next, the electrode substrates A, B having been formed in the abovementioned manner are bonded and fixed by way of a spacer 5 and liquid crystal 6 is injected and sealed therebetween, whereby the liquid crystal cell is provided.</p> |
