A video display device includes a liquid crystal display panel, and light source substrates configured to illuminate the liquid crystal display panel from a rear side of the liquid crystal display panel. Each of the light source substrates includes a plurality of light emitting diodes each of which is provided in corresponding one of areas different from each other in the liquid crystal display panel, and driver elements which drive each of the plurality of light emitting diodes such that light is emitted with luminance corresponding to brightness within a corresponding area of an image in accordance with a control signal. First conductive foil is disposed on a first main surface of the light source substrate on which the light emitting diodes are provided. Second conductive foil is disposed on a second main surface of the light source substrate on a side opposite to the first main surface. Ground pattern foil is disposed as the second conductive foil on the second main surface in regions each of which includes a corresponding one of the plurality of light emitting diodes in a plan view. The first conductive foil and the second conductive foil have a substantially equivalent area.
