Abstract

A liquid crystal display apparatus (100) comprising a liquid crystal display panel (2009 and a touch panel (300) is disclosed. A first transparent electrode (350) is disposed on an upper surface of the liquid crystal display panel (200) for displaying an image. A second transparent electrode (360) is disposed on a lower surface of a retardation member (320) and the second transparent electrode (360) is opposite to the first transparent electrode (350). 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.
