Abstract
A liquid crystal display (LCD) device is disclosed, which comprises a protrusion, and a column spacer being partially overlapped with the protrusion to thereby prevent a cell gap defect. The LCD device includes first and second substrates facing each other and gate and data line crossing each other to define a unit pixel region. In addition a thin film transistor formed adjacent to a crossing of the gate and data lines is included. The protrusions formed on the first substrate correspond with predetermined portions of the gate line. The column spacers are formed on the second substrate with a predetermined portion overlapped with some portion of one of the protrusions. A liquid crystal layer is formed between the first and second substrates.
