1. An LED backlight device, comprising:

  • an LED package provided with an LED chip as a light source, a submount substrate on which the LED chip is mounted, and a sealing resin which seals the LED chip;

    an LED mounting member where a wiring pattern for driving the LED chip is formed and a predetermined number of LED packages are mounted as the LED package; and

    a heat dissipating member having a plurality of LED mounting members mounted thereon as the LED mounting member, and dissipating heat generated by the LED chip when driven,the LED backlight device irradiating a liquid crystal panel with light emitted by a plurality of LED packages disposed behind the liquid crystal panel as the LED package,whereina heat dissipating substrate is provided on which the plurality of LED packages are integrally mounted at a predetermined pitch, the heat dissipating substrate has a wiring pattern formed thereon for driving the LED chip, the submount substrate of each of the LED packages is mounted on the wiring pattern such that the LED packages are mounted directly on the heat dissipating substrate, and the heat dissipating substrate serves both as the LED mounting member and as the heat dissipating member.
