1. A semiconductor device comprising:
a first substrate to which a semiconductor chip is directly or indirectly mounted,
a white insulating layer formed on a reflecting region of the first substrate and functioning as a reflecting material, and
a wiring pattern connected to electrodes is formed on the white insulating layer,
wherein a surface of the reflecting region is substantially flat and made of a metal, and the white insulating layer is formed on the surface of the reflecting region wherein the semiconductor chip is an LED chip disposed in the reflecting region,
wherein the wiring pattern is formed on the surface of the white insulating layer,
wherein the white insulating layer includes white inorganic pigments and SiO2 particles having a mean particle diameter of several nm to several hundred nm,
wherein a rate of SiO2 particles and the white inorganic pigment contained in the white insulating layer is 80% by weight or greater,
wherein a rate of the white inorganic pigments contained in the white insulating layer is 40% by weight or greater,
wherein a rate of the SiO2 particles contained in the white insulating layer is 25% by weight or greater, and
wherein a bottom surface or a side surface of the LED chip is adjacent to the white insulating layer.
