Claim:
1. A liquid crystal display panel comprising: a thin-film transistor electrically connected to lines including a scanning line; a flattened film formed on said thin-film transistor, having a flattened top surface, and having a contact hole formed thereon; a lower electrode formed on said top surface of said flattened film; an insulating film formed on a top surface of said lower electrode; an upper electrode disposed on a top surface of said insulating film, and made of a transparent conductive film having a plurality of slit-like openings formed thereon, the upper electrode being capable of generating an electric field for driving liquid crystal with said lower electrode; and a common line disposed on said top surface of said flattened film as overlapped with said scanning line in a plan view, and electrically connected to said upper electrode, wherein said common line includes a metal line, said lower electrode includes: a flat-plate electrode portion disposed on said top surface of said flattened film and made of a transparent conductive film; and a connection portion formed in said contact hole of said flattened film and electrically connected to said thin-film transistor, said common line is disposed below said insulating film and covered by the insulating film said upper electrode is electrically connected to said common line via an insulating film contact hole being a contact hole formed on said insulating film, and said insulating film contact hole in a plan view is disposed on a part of a region in which said scanning line is disposed, said part not overlapping said thin film transistor.
