Abstract
A liquid crystal display apparatus is disclosed. A first transparent electrode is disposed on an upper surface of the liquid crystal display panel for displaying an image. A second transparent electrode is disposed on a lower surface of a polarizer, and the second transparent electrode is opposite to the first transparent electrode. Accordingly, the entire thickness of the liquid crystal display apparatus may be decreased, and the manufacturing cost of the liquid crystal display apparatus may be reduced.

A liquid crystal display apparatus comprising:
- a liquid crystal panel including a color filter substrate, a thin film transistor substrate and a liquid crystal interposed between the color filter substrate and the thin film transistor substrate;
- and
- a touch panel on the color filter substrate, the touch panel including a first retardation film having a first transparent electrode and a second retardation film having a second transparent electrode spaced apart from the first transparent electrode and making contact with the first transparent electrode by an externally provided pressure to generate a position information of the pressure,
- wherein a plurality of scattering parts are disposed inside at least one of the first and second retardation films.
