PURPOSE: A liquid crystal display is provided to secure quality assurance by displaying a residue time on a screen in real time. CONSTITUTION: In a liquid crystal display, an LCD panel comprises a plurality of liquid crystal cells. A display data processing circuit(111) counts an input synchronization signal. The display data processing circuit generates OSD data related to real time. The display data processing circuit replaces input image data with the OSD data. The panel drive circuit runs data lines and gate lines. A timing controller controls the operation timing of the panel drive circuit. The display data processing circuit comprises a synchronizing signal coefficient(1111), a storage(1112), and an OSD generating unit(1113), and a data processing block(1114).
