Patent ID: 8111225

Claim:
A liquid crystal display device comprising: a liquid crystal panel including plural gate lines to select a pixel and plural data lines to supply pixel data, and a data driver dividing a single frame into plural fields and converting frame data into field data to supply the field data to the data line, wherein of the plural fields, a field on a higher luminance side is shorter than the other field(s) in terms of time, and the single frame is divided into two fields and when a frame time is defined as T, the time of the field on the higher luminance side is defined as L, a response time from 10% to 90% of a finally achieved luminance when a change is made from a black display to a white display is defined as τ 1 , and a response time from 10% to 90% of a finally achieved luminance when a change is made from the white display to the black display is defined as τ 2 , a time proportion of the fields is set to meet an inequality shown below: 0.15 ×T<L 2 /(2.5×τ1)+τ2/(2×τ1)× L< 0.25 ×T.
