Abstract
Description
この構成によれば、複数の行配線と複数の列配線との各交差部において、列配線が形成される面が回路基板の表側の面に統一され、行配線が形成される面が回路基板の裏側の面に統一される。そのため、回路基板の表側の面と裏側の面とを貫通する配線経路(ビア)を減らし易くなる。
前記行配線は、前記行列状の配置における同一の行に属した複数の前記発光素子の前記端子と前記裏側の面に形成された前記行配線とを接続する経路に設けられた複数の前記ビアを含む。
この構成によれば、列に沿って伸びた分岐配線に接続される回路と、列配線に接続される回路とを近くに配置させ易くなり、回路の配置領域がコンパクトになる。また、回路基板の平面視において、分岐配線の列方向延伸部の少なくとも一部が一の列配線と重なるように伸びているため、表示領域の不透明な部分の面積が小さくなる。
この構成によれば、複数対の導体パッドの少なくとも一部が、表側迂回部と兼用される一の導体パッドを含んでいるため、表側迂回部と導体パッドとが兼用されない場合に比べて、表示領域の不透明な部分の面積が小さくなる。また、回路基板の平面視において、発光素子の取り付け領域と重なる位置に裏側迂回部の一部が形成されているため、裏側迂回部が発光素子の取り付け領域から外れた位置に形成される場合に比べて、表示領域の不透明な部分の面積が小さくなる。
この構成によれば、回路基板の平面視において、パッド接続部と重なる位置に裏側迂回部の一部が形成されているため、表示領域の不透明な部分の面積が小さくなる。
図1は、本実施形態に係る表示装置1の外観の一例を示す斜視図である。図2は、図1に示す表示装置1の分解斜視図である。図面を参照した以下の説明では、互いに直交する3つの方向(X、Y、Z)が規定される。X方向は互いに逆向きの方向「X1」及び「X2」を含み、Y方向は互いに逆向きの方向「Y1」及び「Y2」を含み、Z方向は互いに逆向きの方向「Z1」及び「Z2」を含む。表示装置1を中心として、X1方向は左方向、X2方向は右方向、Y1方向は前方向、Y2方向は後方向、Z1方向は上方向、Z2方向は下方向とも呼ばれる。また、X方向は幅方向又は横方向、Y方向は奥行方向又は前後方向、Z方向は高さ方向又は縦方向とも呼ばれる。図1は前方右斜め上から見た斜視図であり、図2は後方右斜め上から見た分解斜視図である。これらの方向は、説明の便宜上規定されたものに過ぎず、表示装置1が使用される態様を限定するものではない。
次に、第2の実施形態に係る表示装置1について説明する。第2の実施形態に係る表示装置1は、上述した第1の実施形態に係る表示装置1における回路基板2の配線のパターン(特に行配線3のパターン)を変更したものであり、他の構成は概ね第1の実施形態に係る表示装置1と同じである。以下では、第1の実施形態に係る表示装置1との相違点を中心に説明する。
