Abstract:
A liquid crystal display device of the field sequential system is realized that is capable of suppressing an occurrence of a color shift.The liquid crystal display device of the field sequential system includes a minimum responsive color difference data correction unit (122) that corrects a data value of pixel data of a color outside a displayable range to a value of a color in the displayable range, a tristimulus value-digital gradation value conversion unit (124) that converts the corrected pixel data to digital gradation data, and a digital gradation data correction unit (126) that performs a correction for over driving on the digital gradation data. The minimum responsive color difference data correction unit (122) determines a color in an uniform color space such that the color is within the displayable range and the color has a smallest color difference from an original uncorrected color, converts data representing the determined color to data represented in the RGB color space, and employs the resultant converted data as the corrected data value of the pixel data.
