The output buffer circuit can obtain an output voltage having a high slew rate even though a smaller amount of a bias current than that required in a conventional output buffer is used. Therefore, the output buffer circuit can reduce power consumption. In the output buffer circuit with a compensation capacitive load, an input part has two input terminal receiving differential input voltage signals, and an output part increases a gain of the differential input voltages. A current source biases the output part, and a slew rate increasing part is connected to the output part and the compensation capacitive load.
