Zusammenfassung:Embodiments of the present disclosure relate to a touch display device in which a shield electrode spaced apart from a common electrode of a light emitting device may be disposed on a region overlapping a touch electrode under an encapsulation layer, and a shield driving signal corresponding to a signal supplied to the touch electrode may be supplied to the shield electrode. Accordingly, the formation of parasitic capacitance between an electrode or a signal line for display driving and the touch electrode may be prevented or reduced by the shield electrode, and touch detection performance may be improved by implementing a noise blocking function using the shield electrode. 本公开的实施方式涉及一种触摸显示装置,与发光器件的公共电极间隔开的屏蔽电极可以设置在与封装层下方的触摸电极交叠的区域上,并且与提供给触摸电极的信号相对应的屏蔽驱动信号可以提供给屏蔽电极。因此,可以通过屏蔽电极防止或减少在用于显示驱动的电极或信号线与所述触摸电极之间形成寄生电容,并且可以通过利用所述屏蔽电极实现噪声阻挡功能来提高触摸检测性能。
