A liquid crystal display device includes: a first substrate having a black matrix, a color filter layer and a common electrode; a second substrate having gate lines, data lines and thin film transistors connected to pixel electrodes; a first alignment layer on the first substrate; a second alignment layer on the second substrate; and a liquid crystal layer having a plurality of liquid crystal molecules and positioned between the first and second alignment layers, wherein each of the first and second alignment layers has a first area with ion-altered side chains and a second area with non-altered side chains.

A method for fabricating a liquid crystal display (LCD) device includes forming a gate electrode and a common electrode line on a first substrate; forming a first insulating layer on the gate electrode; forming an active layer and source/drain electrodes on the first insulating layer; forming a second insulating layer on the source/drain electrodes; forming a photosensitive layer on the second insulating layer; forming a first contact hole, a second contact hole, a first trench and a second trench in the second insulating layer; forming a conductive layer on the photosensitive layer and in the first and second contact holes and the first and second trenches; lifting-off the photosensitive layer to form a pixel electrode electrically connected to the drain electrode through the first contact hole in the first trench and a common electrode electrically connected to the common electrode line through the second contact hole in the second trench; and attaching the first substrate to a second substrate.
