The gate layer is disposed on the substrate. The gate dielectric layer is disposed on the gate layer. The semiconductor layer is disposed on the gate dielectric layer. The first electrode layer is disposed on the semiconductor layer. The first and second passivation layers are sequentially disposed on the first electrode layer. The via penetrates the passivation layers to expose the first electrode layer. The second electrode layer is electrically connected to the first electrode layer through the via. The first and second passivation layers have first and second taper angles respectively. The difference between the first and second taper angles is below 30°."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Display panel","description":"A display panel whose TFT substrate comprises a substrate, a gate layer, a gate dielectric layer, a semiconductor layer, a first electrode layer, a first passivation layer, a second passivation layer,","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9589994","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.
