The liquid composition (S-1) was evaluated in the following order. The evaluation results are shown in Table 2. 'Evaluation of cross-sectional shape> After coating a liquid composition (S-I) onto the surface of a glass substrate using a spin coater, prebaking was performed on a hot plate at 90 ° C for 4 minutes to form a coating having a film thickness of 2.0 μm. membrane. Next, after the substrate was cooled to room temperature, a high pressure mercury lamp was passed through the reticle, and the coating film on the substrate was exposed at an exposure amount of 400 J/m 2 . Then, a shower development was carried out by discharging a 0.04% by weight aqueous solution of 0.04% by weight of 23° C. at 23° C. for 60 seconds at a development pressure of 1.5 kgf/cm 2 (nozzle diameter: 1 mm) on the coating film on the substrate. Next, -31 - 201035683 - post-baking at 220 ° C for 30 minutes to form a 90 μη stripe pixel pattern on the substrate. Next, the cross-sectional shape of the obtained pixel pattern was observed by a scanning electron microscope, and the taper angle shown in Fig. 1 was measured. When the taper angle is 80 degrees or more, the transparent electrode film may be broken. The ideal taper angle is 30 to 70 degrees. Evaluation of solvent resistance Using a spin coater, after coating the liquid composition (S-1) onto the surface of the crucible of the glass substrate, prebaking was performed for 2 minutes on a hot plate of 90° C. to form a film thickness of 2.Ομηη. Coating film. Next, after the substrate was cooled to room temperature, a high pressure mercury lamp was passed through the reticle, and the coating film on the substrate was exposed at an exposure amount of 400 J/m 2 . Then, shower development was carried out by discharging a 0.04 wt% potassium hydroxide aqueous solution at 23 ° C for 60 seconds at a development pressure of 1.5 kgf/cm 2 (nozzle diameter 1 mm) on the coating film on the substrate. Next, post-baking was performed in 220 X: for 30 minutes to form a dot pattern of 200 x 200 μm on the substrate. ^ Next, the obtained substrate was immersed in Ν-methylpyrrolidone at 60 ° C for 30 minutes. As a result, after the immersion lattice pattern was maintained and the immersed N-methylpyrrolidone was not completely colored, it was evaluated as ◎ 'N-methylpyrrolidone after immersion although the dot pattern was maintained after immersion. The case where there were some coloring was evaluated as 〇, and the dot pattern exfoliated from the substrate was observed after immersion, and the coloring of the immersed N-methylpyrrolidone was evaluated as -32 - 201035683 - Evaluation of residual film ratio The liquid composition (s-1) was applied onto the surface of the glass substrate using a spin coater, and then prebaked on a hot plate at 90 ° C for 4 minutes to form a coating film having a film thickness of 2. μm. Next, after the substrate was cooled to room temperature, a high pressure mercury lamp was passed through the reticle, and the coating film on the substrate was exposed at an exposure amount of 400 J/m 2 . Then, by using a coating film on the substrate, a 0.04 wt% potassium hydroxide aqueous solution at 23 ° C for 60 seconds was discharged at a development pressure of 1 kgf/cm 2 (nozzle diameter: 1 mm) to carry out shower development. Next, Ο was post-baked in 220 ° C for 30 minutes to form a dot pattern of 200 χ 200 μm. Next, the lattice pattern on the obtained substrate was observed by a scanning electron microscope, and the film thickness was measured to calculate the residual film ratio (film thickness 后100/1.3 after post-baking). It can be said that the higher the residual film rate, the better the sensitivity.
