A liquid crystal display device includes a TFT substrate having a first alignment film formed on part of an inorganic insulating film, an overcoat film formed on a black matrix, a counter substrate having a second alignment film formed on the overcoat film, and a seal portion including a sealant. The integrated circuit capable of detecting non-rigid-body comprises a best matched block, a correlation unit, and a non-rigid-body detection unit. The supply ratio is defined as a function of the input voltage provided to the switched capacitor voltage converter by the energy supply source.
