More Information
Summary:To provide a touch display device including a small-sized bezel even when touch routing lines connecting a touch sensor to a touch sensing circuit are disposed in a non-display area, and improving touch sensitivity by preventing the formation of parasitic capacitance, which is caused by touch routing lines.SOLUTION: A touch display device, two or more first touch routing lines X-TRW passing through a second non-display area NA2 include touch sensor metal and are disposed to overlap with a common electrode CE extending from a display area AA to the second non-display area NA2. Two or more second touch routing lines Y-TRW passing through a second non-display area NA2 include one or more second touch routing lines Y-TRW_TSM including the touch sensor metal and one or more second touch routing lines Y-TRW_SD including a first metal different from the touch sensor metal.SELECTED DRAWING: Figure 18 【課題】タッチセンサーとタッチセンシング回路とを連結するタッチルーティング配線が非−表示領域に配置されても小さいベゼルサイズを有し、タッチルーティング配線による寄生キャパシタンスの形成を防止してタッチ感度を向上させるタッチ表示装置を提供する。【解決手段】タッチ表示装置であって、第２非−表示領域ＮＡ２を通過する２つ以上の第１タッチルーティング配線Ｘ−ＴＲＷは、タッチセンサーメタルを含み、表示領域ＡＡから第２非−表示領域ＮＡ２まで拡張された共通電極ＣＥと重なって配置される。第２非−表示領域ＮＡ２を通過する２つ以上の第２タッチルーティング配線Ｙ−ＴＲＷは、タッチセンサーメタルが含まれた１つ以上の第２タッチルーティング配線Ｙ−ＴＲＷ＿ＴＳＭと、タッチセンサーメタルと異なる第１メタルが含まれた１つ以上の第２タッチルーティング配線Ｙ−ＴＲＷ＿ＳＤを含むことを特徴とする。【選択図】図１８
