Description
実施の形態1に係る発光表示装置は、駆動トランジスタとキャパシタとを備え、駆動トランジスタのゲート電極が、キャパシタを構成する2つのキャパシタ電極のうち一方の電極である。したがって、キャパシタは、駆動トランジスタのゲート電極を含む領域であって、駆動トランジスタの上方の領域に形成される。
図6は、実施の形態1の変形例に係る発光画素300の回路構成を示す図である。図6に示す発光画素300は、スイッチングトランジスタ101、313、314及び315と、駆動トランジスタ103と、キャパシタ311及び312と、有機EL素子104と、信号線105と、走査線106、316、317及び318と、高電圧側電源線107と、低電圧側電源線108と、参照電圧電源線319とを備える。なお、図3に示す発光画素100と同じ構成については同じ符号を付し、以下では説明を省略する。
図8は、実施の形態1の別の変形例に係る発光画素400の回路構成を示す図である。図8に示す発光画素400は、図6に示す発光画素300と比較して、キャパシタ311の代わりにキャパシタ411を備え、スイッチングトランジスタ313の代わりにスイッチングトランジスタ413を備える点が異なっている。以下では、図6に示す発光画素300と同じ構成については同じ符号を付し、以下では説明を省略する。
実施の形態2に係る発光表示装置は、スイッチングトランジスタと駆動トランジスタとキャパシタとを備え、スイッチングトランジスタのゲート電極が、キャパシタを構成する2つのキャパシタ電極の一方の電極である。したがって、キャパシタは、スイッチングトランジスタの上方の領域に形成される。
