Description
1A.第1実施形態
1A−1.基本構成
図1は、第1実施形態に係る電気光学装置100の平面図である。図2は、図1に示す電気光学装置100のA−A線における断面図である。なお、図1では、対向基板300の図示を省略する。また、以下では、説明の便宜上、互いに直交するX軸、Y軸およびZ軸を適宜用いて説明する。また、X軸に沿う一方向をX1方向といい、X1方向とは反対の方向をX2方向という。同様に、Y軸に沿う一方向をY1方向といい、Y1方向とは反対の方向をY2方向という。Z軸に沿う一方向をZ1方向といい、Z1方向とは反対の方向をZ2方向という。
図3は、素子基板200の電気的な構成を示す等価回路図である。図3に示すように、素子基板200には、n本の走査線241とm本の信号線242とn本の容量線243とが設けられる。nおよびmはそれぞれ2以上の整数である。n本の走査線241とm本の信号線242との各交差に対応してトランジスター240が配置される。各トランジスター240は、例えばスイッチング素子として機能するTFTである。各トランジスター240は、ゲート、ソースおよびドレインを含む。
図4は、図1中のB−B線における素子基板200の断面図である。なお、図4では、各部の構成の理解を容易にするために模式的に示される。以下の説明では、Z1方向を上方とし、Z2方向を下方として説明する。
図5は、第1レンズ構造体280を示す断面図である。図6は、第1レンズ構造体280が有する透光層281を示す平面図である。図5に示すように、第1レンズ構造体280は、透光層281とレンズ層282とを有する。透光層281は、図4に示す基材211とレンズ層282との間に配置される「絶縁層」の例示である。
図7は、第1実施形態に係る電気光学装置100の製造方法の流れを示す図である。図7では、電気光学装置100の製造工程のうち、主に、第1レンズ構造体280の製造工程が代表的に示される。なお、電気光学装置100のうち第1レンズ構造体280以外の構造は、公知の方法により製造できる。また、本明細書において「要素A上に要素Bが形成される」という表現は、要素Aと要素Bとが直接的に接触する場合に限定されない。要素Aと要素Bとが直接的に接触していない場合も、「要素A上に要素Bが形成される」という概念に包含される。また、以下では、素子基板200の製造途中での状態も、素子基板200として説明する。例えば、保護膜290、複数の画素電極220および第1配向膜230を備えていない構造体を素子基板200として記載する場合がある。
第2実施形態を説明する。なお、以下の各例示において機能が第1実施形態と同様である要素については、第1実施形態の説明で使用した符号を流用して各々の詳細な説明を適宜に省略する。
以上に例示した実施形態は多様に変形され得る。前述の実施形態に適用され得る具体的な変形の態様を以下に例示する。以下の例示から任意に選択された2以上の態様は、相互に矛盾しない範囲で適宜に併合され得る。
以上の各形態に例示した素子基板200は、各種構成の電気光学装置100に応用され得る。図21および図22に、各形態に例示した素子基板200の応用例の形態を例示する。
電気光学装置100は、各種電子機器に用いることができる。
