White light emitting device, backlight, liquid crystal display device, and illuminating device

A white light emitting device comprising:

• a blue light emitting diode chip that emits blue light having a light emission peak wavelength of 430 nm to 490 nm;
• a first resin layer that seals the blue light emitting diode chip and includes a cured product of silicone resin;
• and
• a second resin layer that covers the first resin layer and includes phosphor powder, which absorbs the blue light and emits light having a light emission peak wavelength of 500 nm to 570 nm, and a cured product of transparent resin, wherein
• the phosphor powder has a composition represented by the following Formula (1):
• (Sr1-x-yBaxEuy)2SiO4 (1)
• (in Formula (1), x and y satisfy a condition that 0.05<x<0.5 and 0.05<y<0.3, and
• the first resin layer has thickness within a range of 200 μm to 2000 μm, the thickness being a length of a portion present in the first resin layer in a segment connecting a center portion of a bottom surface of the blue light emitting diode chip and a surface of the second resin layer.
