PROBLEM TO BE SOLVED: To provide a small-sized liquid crystal display apparatus capable of supplying stable voltage and provided with an inexpensive power supply IC. SOLUTION: The liquid crystal display apparatus includes a liquid crystal cell, a gate driver, a source driver, a control IC, aγcorrection circuit for supplyingγcorrection voltage, and a power supply IC 13. The power supply IC 13 includes a first power supply circuit 22 for outputting driving voltage for the control IC, the gate driver and the source driver, a second power supply circuit 23 for generating voltage to be applied to column lines through the source drive, third and forth power supply circuits 34, 35 for generating high voltage and low voltage to be mutually switched and applied to row lines through the gate driver, a fifth power supply circuit 25 for generating reference voltage for theγcorrection circuit, and a sixth power supply circuit 26 for generating voltage for a common electrode of liquid crystal cells, which are integrally built in the IC 13.
