A method for fabricating an LCD device includes providing first and second substrates; forming an active layer on the first substrate and forming first and second ohmic contact layers on the active layer; forming a first insulation film on the first substrate; forming a gate electrode on the first substrate; forming a second insulation film on the first substrate; forming a pixel electrode on the first substrate; forming a third insulation film on the first substrate; removing a portion of the first to third insulation film to form first and second contact holes, wherein the first contact hole exposes a portion of the first ohmic contact layer and the second contact hole exposes a portion of the second ohmic contact layer; forming a source electrode electrically connected with the first ohmic contact layer within the first contact hole; forming a drain electrode electrically connected with the second ohmic contact layer and the pixel electrode within the second contact hole; and attaching the first and second substrates.
