To reduce a circuit area of each of a plurality of selection units that selects a voltage to be output from among a plurality of voltages.SOLUTION: In a digital-to-analog conversion circuit, each of a plurality of decoders includes: a plurality of switches that are respectively provided so as to correspond to a plurality of voltages, and switch the output and non-output of the corresponding voltage to an output line; and a plurality of selection units that are respectively provided so as to correspond to the plurality of switches, and to which logical operation results are input. Each of the plurality of selection units controls the corresponding switches by the logical operation results.SELECTED DRAWING: Figure 3 【課題】 複数の電圧の中から出力する電圧を選択する複数の選択部のそれぞれの回路面積を低減する課題を解決する。【解決手段】 複数のデコーダのそれぞれは、複数の電圧のそれぞれに各々が対応するように設けられ、各々が対応する電圧の前記出力線への出力、非出力を切り替える複数のスイッチと、複数のスイッチのそれぞれに各々が対応するように設けられ、論理演算結果が入力される複数の選択部とを有し、複数の選択部のそれぞれは、対応するスイッチを論理演算結果によって制御するデジタルアナログ変換回路である。【選択図】 図３
