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.

A liquid crystal device (“LCD”) device comprising:
- a first substrate and a second substrate, the first substrate facing the second substrate;
- gate lines and data lines, the gate lines crossing the data lines to define a unit pixel region, formed on the first substrate;
- a thin film transistor formed adjacent to a crossing of the gate lines and the data lines;
- protrusions formed on the first substrate;
- column spacers formed on the second substrate, wherein each of the column spacers is arranged in one-to-one correspondence with each of the protrusions and each column spacer has a contacted portion with a portion of an upper surface and a portion of a side surface of the corresponding one of the protrusions;
- and
- a liquid crystal layer formed between the first and second substrates.
An LCD device comprising:
- first and second substrates facing each other;
- gate and data lines crossing each other to define a unit pixel region, formed on the first substrate;
- a thin film transistor formed adjacent to a crossing of the gate and data lines;
- a plurality of protrusions formed on the first substrate corresponding to predetermined portions of the gate lines;
- a plurality of column spacers formed on the second substrate, wherein each of the plurality of column spacers is arranged in one-to-one correspondence with each of the plurality of protrusions and each of the column spacers has a predetermined portion overlapped with some portion of one of the protrusions, and the overlapped portions are different from each other;
- and a liquid crystal layer formed between the first and second substrates.
