The display device is manufactured through, in total, three photolithography steps including one photolithography step which serves as both a step of forming a gate electrode and a step of forming an island-like semiconductor layer, one photolithography step of forming a contact hole after a planarization insulating layer is formed, and one photolithography step which serves as both a step of forming a source electrode and a drain electrode and a step of forming a pixel electrode."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Semiconductor device and method for manufacturing the same","description":"An object is to reduce the number of photomasks used for manufacturing a transistor and manufacturing a display device to less than the conventional one.
