1. A light emitting diode device, comprising:

  • a light emitting diode chip having a first surface on which first and second electrodes are disposed, and a second surface opposing the first surface;

    a wavelength conversion portion including fluorescent substances and covering the first surface and side surfaces of the light emitting diode chip, the side surfaces being placed between the first and second surfaces; and

    first and second electricity connection portions, each including a plating layer, respectively connected to the first and second electrodes, and exposed to the outside of the wavelength conversion portion, wherein;

    a first region of the wavelength conversion portion covering the first surface of the light emitting diode chip includes the fluorescent substances,a second region of the wavelength conversion portion covering the side surfaces of the light emitting diode chip is free of the fluorescent substances,all of the side surfaces of the first and second electricity connection portions are surrounded by the first region of the wavelength conversion portion,the first region of the wavelength conversion portion is formed directly on the first surface of the light emitting diode chip, andthe second region of the wavelength conversion portion covers an entire side surface of the light emitting diode chip.
