Abstract
An electro-optical device includes a DA conversion circuit to convert 10 bits of data into an analog voltage output to a data line. The DA conversion circuit includes a first DA conversion circuit to convert upper 5 bits into a voltage and outputs converted voltage to the data line, a second DA conversion circuit to convert lower 5 bits into a voltage and outputs converted voltage to a relay line, and a coupling capacitance including one end electrically coupled to the second DA conversion circuit and another end electrically coupled to the data line, wherein the first DA conversion circuit includes a capacitance element corresponding to the upper 5 bits and is arranged in the Y direction along the data line, and the second DA conversion circuit includes a capacitance element corresponding to the lower 5 bits and is arranged in the Y direction along the data line.
