Abstract
Description
図1Aは、本実施形態に係る表示装置100の構成を説明する上面図である。表示装置100は、表示領域102aと、周辺領域102bと、端子領域102cとを有している。
図9は、本実施形態に係る表示装置200の構成を説明する上面図である。表示装置200は、第1実施形態に係る表示装置100と比べると、貫通孔110cのレイアウトが異なっている。本実施形態においては、貫通孔110cは、矩形状の表示装置200において、その3辺に沿って設けられている。つまり、端子領域102cが設けられる1辺には、貫通孔110cが設けられていない。
図10は、本実施形態に係る表示装置300の構成を説明する断面図である。表示装置300は、第1実施形態に係る表示装置100と比べると、封止層124の構成が異なっている。本実施形態においては、封止層124の端部は、周状の貫通孔110cの内側に配置されている。これによって、貫通孔110cは、無機絶縁層122d、第2無機絶縁層110b、ゲート絶縁層108b及び第1無機絶縁層110aを貫通する。つまり、貫通孔110cは、封止層124の第4無機絶縁層124c及び第3無機絶縁層124aが積層された部分は貫通しない。これによって、第1実施形態に比べ、製造工程において貫通孔110cを形成するためのレーザの強度を低く抑えることができ、製造コストを抑えることができる。
図11は、本実施形態に係る表示装置400の構成を説明する断面図である。表示装置400は、第1実施形態に係る表示装置100と比べると、封止層124の構成が異なっている。本実施形態においては、封止層124を構成する第1有機絶縁層124bは、端部が貫通孔110cの外側に配置されている。これに伴い、表示装置400の周縁に形成される貫通孔110cは、第4無機絶縁層124c、第1有機絶縁層124b、第3無機絶縁層124a、無機絶縁層122d、第2無機絶縁層110b、ゲート絶縁層108b及び第1無機絶縁層110aを貫通している。これによって、製造工程において、貫通孔110cを形成する際に、無機絶縁層122dから下層の各層が封止層124によって保護された状態でレーザが照射される。これによって、無機絶縁層122dから下層において、レーザ照射によって懸念される無機材料の飛散やピーリングの発生を抑えることができ、ひいてはこれらに起因して回路層104の絶縁層110に欠陥が生じることを抑えることができる。これによって、製造歩留まりが向上し、信頼性の向上した表示装置400を提供することができる。
図12は、本実施形態に係る表示装置500の構成を説明する断面図である。表示装置500は、第4実施形態に係る表示装置400と比べると、保護層126の構成が異なっている。本実施形態においては、保護層126は、端部が周状の貫通孔110cの外側に配置されている。これに伴い、表示装置500の周縁に形成される貫通孔110cは、第4無機絶縁層124c、第1有機絶縁層124b、第3無機絶縁層124a、無機絶縁層122d、第2無機絶縁層110b、ゲート絶縁層108b及び第1無機絶縁層110aに加え、保護層126を更に貫通している。これによって、第4実施形態と同様に、製造工程において貫通孔110cを形成する際に、無機絶縁層122dから下層の各層が封止層124によって保護された状態でレーザが照射される。これによって、無機絶縁層122dから下層において、無機材料の飛散やレーザ照射によって懸念されるピーリングの発生を抑えることができ、ひいてはこれらに起因して回路層104の絶縁層110に欠陥が生じることを抑えることができる。更に、第4無機絶縁層124cが保護層126によって保護された状態でレーザが照射される。これによって、レーザ照射の際に、第4無機絶縁層124cの無機材料が飛散することを抑制することができ、ひいてはそれが起点となって回路層104に欠陥が生じることを抑制することができる。これによって、製造歩留まりが向上し、信頼性の向上した表示装置500を提供することができる。
