The liquid crystal display device of the present invention includes a first substrate, a liquid crystal layer, and a second substrate, in this order. The first substrate has pixel electrodes having a structure composed of a trunk portion and a plurality of branch portions that branch off from the trunk portion. The liquid crystal display device has a display region that includes a region where the branch portions and slits are alternately disposed. The display region has a reflective region and a transmissive region. The reflective region has a pixel electrode, a reflective film disposed under the pixel electrode, and a λ/4 retarder plate. The first best-fit curve, which is obtained from the gamma curve of the reflective display, is above the second best-fit curve, which is obtained from the gamma curve of the transmissive display, except in the regions where the reflectance of the first best-fit curve and the transmittance of the second best-fit curve are both 0% and 100%. The first best-fit curve does not have a gradation reversal and has an inflection point.
