1. A liquid crystal display device, comprising:

  • a liquid crystal display panel having a display surface and a rear surface, which is on a side opposite to the display surface; and

    a backlight, wherein;

    the backlight comprises;

    a plurality of light emitting diodes;

    a substrate on which the plurality of light emitting diodes are mounted; and

    a reflection sheet, which overlaps the substrate at a surface on which the plurality of light emitting diodes are mounted in a manner without overlapping the plurality of light emitting diodes;

    the surface on which the plurality of light emitting diodes are mounted of the substrate is opposed to the rear surface of the liquid crystal display panel;

    the liquid crystal display panel and the substrate each have a shape in which a common width in a first direction is longer than a width in a second direction, which is orthogonal to the first direction;

    the width of the substrate in the second direction is shorter than the width of the liquid crystal display panel in the second direction, the substrate being opposed to, while avoiding being opposed to both end portions of the liquid crystal display panel in the second direction, a central portion between the both end portions of the liquid crystal display panel;

    pitches between adjacent light emitting diodes of the plurality of light emitting diodes are smaller as the adjacent light emitting diodes are closer to a center of the substrate in the first direction;

    the substrate is divided into a first divided substrate and a second divided substrate between adjacent light emitting diodes having a smallest pitch among the pitches;

    at least one of the first divided substrate and the second divided substrate includes, at one end portion of the at least one of the first divided substrate and the second divided substrate, a cable connector for connection to a cable; and

    the first divided substrate and the second divided substrate are disposed so that another end portion of the first divided substrate and another end portion of the second divided substrate are adjacent to each other.
