A short-circuiting circuit short-circuits source bus lines such that a sum of numbers assigned to two source bus lines forming each set in each group is equal for all sets when it is assumed that K consecutive source bus lines (K is an even number greater than or equal to 4) form one group and numbers from 1 to K are assigned to the K source bus lines. For example, with four consecutive source bus lines forming one group, in each group, the short-circuiting circuit short-circuits the first and fourth source bus lines and short-circuits the second and third source bus lines.

Video signal line drive circuit, display device including same, and drive method for video signal line

A display device includes a display panel having a display surface, display drivers arranged on and along a peripheral portion of the display panel, a wiring substrate located on a side of the display panel opposite from the display surface and having a long shape extending in an arrangement direction of the display drivers, first flexible wiring substrates electrically connecting the display drivers to the wiring substrate, a second flexible wiring substrate extending from the wiring substrate toward an outer periphery of the display panel, and a control board connected to an extended end portion of the second flexible wiring substrate and configured to control the display drivers and disposed not to overlap the display panel in a thickness direction of the display panel and having a dimension in the thickness direction of the display panel larger than that of the wiring substrate.

Display device

A liquid crystal display device includes a liquid crystal panel and a control unit. The control unit stores a plurality of setting values of a voltage applied to a counter electrode. The setting value is a value of the applied voltage at which variation in luminance appears at a portion located apart from a reference portion that is a region in the liquid crystal panel.
