Disclosed is a field-sequential-color display device sequentially driving a plurality of color fields divided from any one frame of a plurality of frames, including: a processor calculating a second field brightness-correction-value of a second color field based on a first field transition-brightness-value transferred from a first color field; and a display unit controlling the second color field based on the second field brightness-correction-value. Correction data is calculated by reflecting a brightness-value transited between color fields in a display to a non-linear brightness-value displayed in the corresponding field to minimize an error caused due to a difference between linear image data and a non-linear brightness-value displayed in the display.
