Patent ID: 7259813

Claim:
A display apparatus configured by sandwiching a liquid crystal layer between a first substrate having a first electrode and a second substrate having a second electrode, wherein said first substrate further comprises: a switching element provided to each pixel and including a thin film transistor in which a gate is formed above an active layer; a gate insulating film including a silicon oxide and formed between said gate and said active layer of said thin film transistor; an interlayer insulating flm formed covering said gate and said gate insulating film; a reflective layer formed above said interlayer insulating film so as to be insulated from said active layer of said film transistor, said reflective layer reflecting light incident from a side of said second substrate and said second electrode, both of which are transparent, into said liquid crystal layer, and a passivation film formed covering said reflective layer, and wherein said first electrode made of a transparent conductive material is electrically and directly connected to said active layer via a contact hole formed by opening a hole through at least said gate insulating film, said interlayer insulating film, and said passivation film which are formed between said first electrode and said active layer; said passivation film has endurance to a slight etching material which exposes a surface of said active layer made of silicon at a bottom of said contact hole; and said passivation film is made of a silicon oxide.
