A IF inversion driving method writes signal voltage of the same polarity to a signal line over a 1F period, and therefore cannot prevent occurrence of crosstalk caused by coupling. Also, shading is caused. In an active matrix type liquid crystal display device including a pixel array unitformed by two-dimensionally arranging pixelsin a form of a matrix, the pixel array unitis divided into a plurality of areas (two areasA andB in a present example) in a vertical direction, while the plurality of areas being vertically scanned in order (alternately in the present example) in a unit of a row, pixels of the plurality of areas are selected in a unit of a row, and a video signal Vsig reversed in polarity in each H is written to the pixels of the selected row.

Display device and driving method of display device

A light-shielding plate and a first light-shielding layer are arranged between a polarizing plate and a liquid crystal layer in a peripheral region of a liquid crystal panel so that linearly polarized light transmitted through the polarizing plate, which is a reflection polarizing plate, is not incident on the liquid crystal layer, but is reflected to the polarizing plate in the peripheral region.
