The composition is prepared by a method comprising the step of blending the foregoing components. The porous silica precursor composition is coated on a substrate and then fired to thus form a porous silica film. Also disclosed herein include a semiconductor element, an apparatus for displaying an image and a liquid crystal display, each having the foregoing porous silica film."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Porous silica precursor composition and method for preparing the precursor composition, porous silica film and method for preparing the porous silica film, semiconductor element, apparatus for displaying an image, as well as liquid crystal display","description":"A porous silica precursor composition is herein provided and the precursor composition comprises an organic silane represented by the following chemical formula 1: R1m(R2—O)4-mSi (in the formula, R1 a","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8471140","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
