AI Technical Summary
【0009】 本願の実施例の表示パネルによれば、表示パネルは、基板と、第1絶縁層と、第1電極層と、タッチ電極層とを含む。第1絶縁層に接続ビアが開設されていることにより、第1電極は、接続ビアを通じて薄膜トランジスタと電気的に接続することができ、薄膜トランジスタは第1電極に信号を伝送することができる。タッチ電極層はタッチ電極を含み、タッチ電極はタッチ線を含み、タッチ線は、タッチ信号を伝送し、表示パネルのタッチ機能を実現することに用いられる。第1絶縁層に接続ビアが設けられているため、第1絶縁層の基板とは反対側に位置するフィルム層は、接続ビアの位置する領域で凹む可能性があり、フィルム層の表面は不平坦になる。接続ビア内に第1電極等の金属材料が更に充填され、これらの金属材料は光を反射し、不平坦な表面によって反射された光は、表示パネルの表示効果に影響を及ぼす可能性がある。本願の実施例において、タッチ線の基板における正投影と、接続ビアの基板における正投影とが少なくとも部分的に重なり、タッチ線は一部の接続ビアを覆い、更に一部の不平坦な表面を覆い、表示パネルの表示効果を改善し、表示パネルの使用性能を向上させることができる。
