Claim:
1. A driver comprising: a control circuit that outputs detection data or image data to a capacitor driving circuit, the capacitor driving circuit outputting first to nth capacitor driving voltages where n is a natural number of 2 or more, corresponding to the image data to first to nth capacitor driving nodes; a capacitor circuit including first to nth capacitors provided between the first to nth capacitor driving nodes and a data voltage output terminal; a detection circuit that carries out a detection that detects a connection state between the data voltage output terminal and an electro-optical panel during a time when the control circuit outputs the detection data, wherein the detection circuit is a circuit that detects a voltage at the data voltage output terminal; and wherein the control circuit determines the connection state based on a result of detecting a voltage provided by the detection circuit, corresponding to the detection data, at the data voltage output terminal.
