1.実施の形態(基板の裏面に磁性支持部材が設けられた表示装置の例)
2.表示装置の機能構成例
3.撮像装置の例
4.電子機器の例
[表示装置1の構成]
図1は、本技術の一実施の形態に係る表示装置(表示装置1)の断面構成を模式的に表したものである。表示装置1は、例えば有機電界発光(EL:Electro-Luminescence)装置であり、半導体装置10上に表示素子層20を備えたものである。表示装置1は、例えば、トップエミッション型の表示装置であり、表示素子層20で発生した光は、半導体装置10と反対側から取り出されるようになっている。半導体装置10は、複数のTFT(Thin Film Transistor)10aを有している。表示素子層20は、複数の有機EL素子20Aを有している。図1には、1つのTFT10aおよび1つの有機EL素子20Aを表す。
次に、図4および図5A~図5Eを用いて、表示装置1の製造方法について説明する。図4は、表示装置1の製造方法の一例を表す流れ図であり、図5A~図5Eは、図4に示した各工程を表す断面模式図である。
本実施の形態の表示装置1では、外部から入力される映像信号に基づいて、表示素子層20の各画素pr,pg,pbが表示駆動され、映像表示がなされる。有機層23で発生した光は、例えば、第2電極24および保護膜25を介して取り出される。このとき、半導体装置10のTFT層13では、例えば画素pr,pg,pb毎にTFT10aが電圧駆動される。具体的には、ある画素(画素pr,pg,pbのいずれか)のTFT10aのゲート電極133に閾値電圧以上の電圧が供給されると、半導体層131が活性化され(チャネルを形成し)、これにより、一対のソース・ドレイン電極135A,135B間に電流が流れる。
図6は、上記実施の形態において説明した表示装置1の機能ブロック構成を表すものである。
上記実施の形態等では、半導体装置10の適用例として表示装置1を例に挙げて説明したが、半導体装置10は、表示装置1の他にも、図7に示したような撮像装置(撮像装置6)に用いられてもよい。
上記実施の形態等において説明した表示装置1(または撮像装置6)は、様々なタイプの電子機器に用いることができる。図8に、電子機器7の機能ブロック構成を示す。電子機器7としては、例えばテレビジョン装置、パーソナルコンピュータ(PC)、スマートフォン、タブレット型PC、携帯電話機、デジタルスチルカメラおよびデジタルビデオカメラ等が挙げられる。
