Description
本発明の実施の形態について、図面を用いて詳細に説明する。但し、本発明は以下の説明に限定されず、本発明の趣旨及びその範囲から逸脱することなくその形態及び詳細を様々に変更し得ることは当業者であれば容易に理解される。従って、本発明は以下に示す実施の形態の記載内容に限定して解釈されるものではない。なお、以下に説明する本発明の構成において、同一部分又は同様な機能を有する部分には同一の符号を異なる図面間で共通して用い、その繰り返しの説明は省略する。
本実施の形態では、第1の電極と配線との接続構造が異なる本発明の表示装置の例を図3及び図4を用いて説明する。
本実施の形態では、実施の形態1で作製した表示装置において、両面出射型、片面出射型である上面出射型の例を、図6及び図7を用いて説明する。
本実施の形態では、逆スタガ型TFTの一例を図8及び図9に示す。TFT以外の部分は、最良の形態における実施の形態1で示した表示装置と同一であるのでここでは詳細な説明は省略する。
走査線側入力端子部と信号線側入力端子部とに保護ダイオードを設けた一態様について図17を参照して説明する。図17において画素2702にはTFT501、502、容量504、発光素子503が設けられている。このTFTは実施の形態4と同様な構成を有している。
図13は、本発明によって作製される、TFT基板2800を有するEL表示モジュールを構成する一例を示している。同図面において、TFT基板2800上には、画素により構成された画素部が形成されており、TFT2802、2803を有している。
本発明によって形成される表示装置によって、テレビジョン装置を完成させることができる。表示パネルには、図14(A)で示すような構成として画素部のみが形成されて走査線側駆動回路と信号線側駆動回路とが、図15(B)のようなTAB方式により実装される場合と、図15(A)のようなCOG方式により実装される場合と、図14(B)に示すようにSASでTFTを形成し、画素部と走査線側駆動回路を基板上に一体形成し信号線側駆動回路を別途ドライバICとして実装する場合、また図14(C)のように画素部と信号線側駆動回路と走査線側駆動回路を基板上に一体形成する場合などがあるが、どのような形態としても良い。
本発明を適用して、様々な表示装置を作製することができる。即ち、それら表示装置を表示部に組み込んだ様々な電子機器に本発明を適用できる。
