PURPOSE: An image signal compensation circuit is provided to restrain reduction of quality, such as burn-in by preventing application of a DC component into a liquid crystal capacitor. CONSTITUTION: The image signal compensation circuit(300) includes a compensation-level output unit(312), a selector(316), and an adder(318). From among these components, the compensation-level output unit(312) outputs a compensation level(Cmp) in response to the image signal(VID), which is a digital signal before being subjected to the polarity inversion by the polarity inverter circuit, and which has information indicating the gray level of a pixel. The compensation-level output unit(312) includes a table, an address generator, and an interpolation unit. From among these components, the table stores beforehand compensation levels, which correspond to five gray levels, respectively, and outputs a compensation level designated by an address.
