Abstract
Discussed are a gamma reference voltage output circuit and a display device. The gamma reference voltage output circuit includes an (N)th operational amplifier configured to output an (N)th gamma reference voltage through an (N)th output terminal, where N is a natural number, an (N+1)th operational amplifier configured to output an (N+1)th gamma reference voltage being lower than the (N)th gamma reference voltage through its (N+1)th output terminal, an (N+2)th operational amplifier configured to output an (N+2)th gamma reference voltage being lower than the (N+1)th gamma reference voltage to an (N+2)th output terminal, and one or more connection nodes to which a power terminal of one of adjacent operational amplifiers in the (N)th operational amplifier, the (N+1)th operational amplifier, and the (N+2)th operational amplifier is connected to an output terminal of another operational amplifier.
