Abstract
Abstract The present invention includes a substrate for a display device and a liquid crystal display device using the same having a functional layer at least partially made of an organic-inorganic hybrid glass. The present invention includes a method of manufacturing a substrate for a display device having the steps of forming a switching element on a substrate, forming a polysilane layer on the substrate, irradiating ultraviolet light to the polysilane layer, to form a latent image for a pattern, dipping the substrate into a dipping solution so that a material of the dipping solution soaks into the exposed portion, vitrificating the exposed portion by heating. According to the method, a pattern having different regions in characteristics (insulating, conductive, and coloring) can be formed easily by changing in composition of the dipping solution.
