A display data processing circuit and liquid crystal display device are provided which are capable of performing conversions between input display data and output display data even with reduced memory capacity. The display data processing circuit includes a storing section to store a power value of a decimal portion of a coefficient setting value, processing section to calculate a power value of an integral portion of the coefficient setting value and to perform a multiplication among the value obtained by the calculation, a value read from the storing section, and a number of gray-scale levels of the input display data, and a look-up table to convert a gray-scale value of input display data to a gray-scale value of output display data based on the coefficient setting value by storing values corresponding to all gray-scale values that the input display data can take on and by reading the value obtained from multiplication by the processing section corresponding to gray-scale values of input display data.
