PURPOSE: A light guide reflective plate capable of controlling transmittance and reflectance, and a manufacturing method thereof are provided to obtain uniform intensity of radiation. CONSTITUTION: A light guide reflective plate(100) includes a base plate(110), diffuser(120), metallization base layer(130), and reflective film(140). The base plate is made of transparent material in a flat shape. Diffuser is formed on the surface of the base plate in a dotted pattern. The metallization base layer is made of transparent material and surrounds the surface of the diffuser. The reflective film is formed on the surface of the metallization base layer by vacuum metallization. |
