Abstract:
1. A liquid crystal display device comprising: a plurality of scanning signal lines; a plurality of data signal lines; a first pixel including a first liquid crystal layer; a second pixel including a second liquid crystal layer having a thickness smaller than a thickness of the first liquid crystal layer; a third pixel including a third liquid crystal layer having a thickness smaller than the thickness of the second liquid crystal layer; and a gray scale transition emphasis process section for respectively setting first through third output gray scales of a current frame on the basis of (i) first through third input gray scales of the current frame and (ii) first through third gray scales of a frame which is one frame before the current frame, the first through third output gray scales being respectively set for the first through third pixels in accordance with the thicknesses of the respective first through third liquid crystal layer so that (i) the second output gray scale for the second pixel is higher than the third output gray scale for the third pixel and (ii) the first output gray scale for the first pixel is higher than the second output gray scale, in a case where the first through third pixels display an identical gray scale, wherein: the first through third output gray scales are calculated by adding or subtracting, to or from the first through third input gray scales, respectively, an amount of gray scale transition and in a case where an amount of gray scale transition in the second pixel is preset, (i) an amount of gray scale transition in the first pixel is calculated on the basis of (a) the thickness of the second liquid crystal layer and (b) a difference in thickness between the first liquid crystal layer and the second liquid crystal layer and (ii) an amount of gray scale transition in the third pixel is calculated on the basis of (c) the thickness of the second liquid crystal layer and (d) a difference in thickness between the second liquid crystal layer and the third liquid crystal layer.
