Abstract
A large-area transmissive type optical image modulator, a method of manufacturing the same, and an optical apparatus including the transmissive type optical image modulator are provided. The large-area transmissive type optical image modulator includes: a base substrate; a first expitaxial layer formed on the base substrate; a second expitaxial layer formed on the first expitaxial layer; a first electrode formed on the first expitaxial layer and spaced apart from the second expitaxial layer; a second electrode formed on the second expitaxial layer; and a transparent substrate covering the second expitaxial layer and the second electrode, wherein the base substrate includes a through hole corresponding to a light emitting area, and the first expitaxial layer may include an n-type or p-type doping material.
