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には、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。
