METHOD FOR PREPARING PIXEL DEFINE LAYER

Abstract: provided is a method to prevent interference between electrodes that causes pixel defects in a pixel defining layer, thereby lowering the touch defect rate of the panel, and implementing a coloring pattern with high optical density on the electrode substrate to not only make the colors vivid but also increase the reliability and lifespan of the display, particularly a composition and a method for forming a pixel defining layer pattern, which comprises a colorant, and the coating film formed by treating at high temperature during post-baking treatment has a high optical density (od) per thickness, has a low permittivity of 5.0 or less even with changes in measured hz, and can improve visibility and contrast.
