Description
本実施の形態では、本発明の発光装置の画素部について、図1(A)(B)を用いて詳細に説明する。
本実施の形態では、図1(A)に示す本発明の発光装置の作製方法の一例について、図2〜4を参照して説明する。
本実施の形態では、可撓性基板として繊維体に有機樹脂を含浸させた構造体を用い、また、可撓性基板上に低温プロセスで作製することができる薄膜トランジスタを有する発光装置の作製方法について説明する。なお、本実施の形態では、酸化物半導体を用いた薄膜トランジスタを形成する場合について説明する。
本実施の形態4では、本発明の発光装置について図7を用いて説明する。
本実施の形態では、本発明を適用して作製した発光装置を用いて完成させた様々な電子機器について、図8を用いて説明する。本発明の発光装置は、外側が一対の可撓性基板に覆われたフレキシブルな構造を有し、薄膜軽量化が図られているだけでなく、内部構造が耐衝撃性に優れているため様々な電子機器に適用することができる。
