Display apparatus
Abstract:
[PROBLEM] To reduce a time constant of an electric circuit including driving electrodes and detecting electrodes in a display provided with an input device, and reduce a temperature variation ratio of the time constant.[SOLVING MEANS] The display 1 includes driving electrodes COML provided along an X axis direction when seen in a plan view, buffer TFT elements Trb serially connected to the driving electrodes COML, and a plurality of detecting electrodes TDL respectively provided to intersect with the driving electrodes COML when seen in a plan view and aligned in the X axis direction. A temperature coefficient of resistance of a sum of an ON resistance of the buffer TFT elements Trb and a resistance of the driving electrodes COML is negative, each of the specific resistances of the plurality of detecting electrodes TDL is not more than 40 μΩcm, and each of the temperature coefficients of resistance of the plurality of detecting electrodes TDL is 1×10−3 to 5×10−3K−1.
