Abstract: A liquid crystal display apparatus includes a liquid crystal layer, a light source, a first polarizing member, and a reflector. The first polarizing member includes a wire-grid polarizing part and a reflection part. The first polarizing member is disposed between the liquid crystal layer and the light source. The reflector is disposed below the light source. The reflector reflects light from the light source and light reflected from the reflection part.

Abstract: A method of manufacturing a display apparatus, the method includes removing an oxide layer formed on a surface of a substrate by utilizing a hydrofluoric acid gas and an ammonia gas, and thermally treating the substrate from which the oxide layer has been removed. A flow ratio between the hydrofluoric acid gas and the ammonia gas is about 0.8:1 to about 1:1.
