Abstract
A display device is composed of a liquid crystal display panel, having modulating characteristics in which a relationship between a transmittance and a drive voltage depends on the direction of a change in the drive voltage, for modulating source light in a two-dimensional area, and a processing channel for applying a drive voltage according to each of pixel signals which change for each 1-field period. Particularly, the processing channel includes a field memory for delaying transmittance data corresponding to the pixel signal by the 1-field period, and a characteristic compensating circuit for converting the transmittance data to a drive voltage data on the basis of conversion characteristics which vary with the data delayed by the field memory, and determining the drive voltage according to the drive voltage data.
