Abstract
An amplifier circuit and display device utilizing the amplifier circuit are provided. The amplifier circuit comprises a buffer amplifier which stabilizes an input signal and outputs a stabilized output signal. By supplying to the input terminal of the buffer amplifier, a voltage derived by adding a difference between the input signal and the output signal to the input signal, it is possible to change the input signal level in accordance with the deviation of the buffer amplifier, which allows correction of the output level to a suitable level.
