Abstract
In a semiconductor device 100, a light emitting device 102 is mounted on a substrate 101. A light reflection preventing film 130 for preventing a reflection of a light is formed on an upper surface of the light emitting device 102. Moreover, a plate-shaped cover 103 formed of a glass having a light transparency is disposed above the light emitting device 102, and a light reflection preventing film 140 for preventing a reflection of a light is also formed on an upper surface of the cover 103.
