Description
図1は、本発明の一実施形態に係る表示装置100を示す斜視図である。表示装置100は、絶縁表面を有する基板102の一主面に画素部104、タッチセンサ108が配置されている。画素部104は、複数の画素106が配置される。複数の画素106は、画素部104において、例えば、行方向及び列方向に配列される。タッチセンサ108は、画素部104に重ねて配置される。別言すれば、タッチセンサ108は、複数の画素106と重なるように配置される。タッチセンサ108は、複数の検出電極107がマトリクス状に配置され、それぞれが行方向あるいは列方向に接続される。なお、ここでは画素106およびタッチセンサ108は模式的に表現されており、その大小関係は図1記載の限りではない。
図8は、本実施形態に係る表示装置200の周辺領域の構成を示す平面図であり、図9は、本実施形態に係る表示装置200の構成を示す断面図である。図8及び図9に示す表示装置200は、第1実施形態にかかる表示装置100と異なり、第1検出電極134と第1配線136とを接続する開口部133が、開口領域120の外側に設けられている。本実施形態では、第1配線136は、開口領域120を横断して開口部133まで延長されている。
ただし、第1検出電極134と第2検出電極140とは、少なくとも第2無機絶縁層132によって絶縁されていれば足りるため、本実施形態においても表示装置100と同様に第1検出電極134が、第1無機絶縁層128と有機絶縁層130との間に設けられていてもよい。
図10は、本実施形態に係る表示装置300の周辺領域の構成を示す平面図であり、図11は、本実施形態に係る表示装置300の構成を示す断面図である。図10及び図11に示す表示装置300は、第1実施形態にかかる表示装置100と異なり、開口領域120が、第2端子115a、115bの外側に設けられており、かつ、第1検出電極134と第1配線136とを接続する開口部133が、第2端子115a、115bの内側に設けられている。表示装置300のその他の構成は表示装置100と同様である。
