A liquid crystal display device having a thin-film transistor for driving a pixel electrode and a storage capacity element on a substrate, comprising:
- said storage capacity element being formed to underlie a thin-film semiconductor layer forming said thin-film transistor wherein said storage capacity element is made of a structure interposing a storage capacity dielectric film between a storage capacity line and a storage capacity pixel electrode.
A manufacturing method of a liquid crystal display device having a thin-film transistor for driving a pixel electrode and a storage capacity element on a substrate, characterized in:
- making said storage capacity element on said substrate;
- and
- making said thin-film transistor to overlie said storage capacity element via an inter-layer insulating film wherein said storage capacity element is made by sequentially stacking a storage capacity pixel electrode, a storage capacity dielectric film and a storage capacity line on said substrate.
