ABSTRACT:
A liquid crystal display device including a gate electrode and a gate line formed on a first substrate, a first insulating layer formed on the first substrate, an active pattern, an ohmic-contact layer, and a diffusion preventing layer formed on the gate electrode, a data line to cross source and drain electrodes and the gate line formed on the diffusion preventing layer to define a pixel area, a second insulating layer formed on the first substrate, a contact hole formed by removing a portion of the second insulating layer and exposing a portion of the drain electrode, a pixel electrode electrically connected with the drain electrode via the contact hole, and a second substrate attached with the first substrate in a facing manner, wherein the diffusion preventing layer comprises a metal tip protruded to the side of the source and drain electrodes.
