Description
本実施の形態では、本発明の一態様の剥離の起点の形成方法、剥離方法、及び剥離装置について、図1〜図7を用いて説明する。
図1(A−1)、(B−1)、(C−1)に加工部材の断面図を示し、図1(A−2)、(B−2)、(C−2)に加工部材の上面図を示す。図1(A−1)、(B−1)、(C−1)は、それぞれ、図1(A−2)、(B−2)、(C−2)に示す一点鎖線X1−X2間の断面図である。
以下に、加工部材に用いることができる材料の一例を挙げる。
次に、本発明の一態様の剥離の起点の形成方法を用いて、上記とは異なる構成の加工部材から被剥離層を剥離する方法について、説明する。
図7に、剥離装置の構成例を示す。
本実施の形態では、本発明の一態様に適用可能な発光パネルの構成と作製方法について図8〜図18を用いて説明する。本実施の形態では、発光素子としてEL素子が適用された発光パネルを例に説明する。
図9(A)、(B)に、カラーフィルタ方式が適用されたトップエミッション構造の発光パネルの断面図を示す。
図10(A)に、カラーフィルタ方式が適用された発光パネルの断面図を示す。なお、以降の構成例では、先の構成例と同様の構成については、詳細な説明を省略する。
図10(B)に、塗り分け方式が適用された発光パネルの断面図を示す。
本発明の一態様では、タッチセンサが搭載された発光パネル(以下、タッチパネルとも記す)を作製することができる。
図11(A)は、タッチパネル300の斜視概略図である。図11(B)は、図11(A)を展開した斜視概略図である。なお明瞭化のため、代表的な構成要素のみを示している。図11(B)では、一部の構成要素(基板330、基板372等)を破線で輪郭のみ明示している。
基板330の基板372側には、電極331及び電極332が設けられている。ここでは、電極331が、電極333及び電極334を有する場合の例を示している。図12中の交差部387に示すように、電極332と電極333は同一平面上に形成されている。絶縁層395は、電極332及び電極333を覆うように設けられている。電極334は、絶縁層395に設けられた開口を介して、電極332を挟むように設けられる2つの電極333と電気的に接続している。
図13(A)に示すタッチパネルは、接着層391を有していない点、及び、トランジスタ301、302、303、及び容量素子305の構成が異なる点で、図12に示すタッチパネルと異なる。
図14に示すタッチパネルは、塗り分け方式が適用された発光パネルと、入力パネルと、を接着層375で貼り合わせた例である。
図15は、一対の可撓性を有する基板(基板371及び基板372)の間に、タッチセンサ及び発光素子304を有する例である。可撓性を有する基板を2枚とすることで、タッチパネルの薄型化、軽量化、さらにはフレキシブル化が可能となる。
図16(A)、(B)は、タッチパネル320の斜視概略図である。
図18(A)に示すタッチパネルは、タッチセンサを構成する電極等と、基板372との間に遮光層326が設けられている。具体的には、絶縁層376と絶縁層328の間に遮光層326が設けられている。基板372側から見て、絶縁層328上には、電極332、電極333、配線342等の導電層と、これらを覆う絶縁層395と、絶縁層395上の電極334等が設けられている。また、電極334及び絶縁層395上に、絶縁層327が設けられ、絶縁層327上に着色層325が設けられている。
本実施の形態では、本発明の一態様の電子機器及び照明装置について、図面を用いて説明する。
