Classification: CPC G | IPC G

Claim 0:
1. A liquid crystal display device comprising:
a liquid crystal layer provided between a first substrate and a second substrate;
a detection electrode configured to detect an external proximity object;
a plurality of pixels overlapping the detection electrode in plan view; and
a detection circuit configured to detect a detected capacitance value generated in the detection electrode, wherein
a liquid crystal capacitance value generated between each of the pixels and the detection electrode includes a first capacitance value at a first gradation and a second capacitance value at a second gradation smaller than the first gradation, and
the detection circuit corrects the detected capacitance value based on a ratio between number of pixels with the first gradation and number of pixels with the second gradation out of the pixels.
