ABSTRACT:
An LCD device and a method for manufacturing the same are disclosed, in which a protrusion is arranged to substantially oppose a column spacer to reduce a contact area between the column spacer and its opposing substrate, and the protrusion is formed of an organic material to minimize deformation of the column spacer. The LCD device further comprises first and second substrates opposing each other, gate and data lines crossing each other on the first substrate to define pixel regions, thin film transistors formed at crossings of the gate lines and the data lines, a first column spacer formed of a first organic material on a predetermined portion of the second substrate, a protrusion formed of a second organic material on the first substrate of a position substantially corresponding to the first column spacer, and a liquid crystal layer filled between the first and second substrates.
